Retrieve the history of audited data changes

Чланак
02/29/2024

When auditing is enabled and data in audited tables and columns is changed, you can retrieve the change history of those tables and columns.

Audit data isn't available using the Dataverse TDS (SQL) endpoint.

Audit history is not available for tables in the mobile app.

Audit table

Auditing events are stored in the Auditing (Audit) table. In the Web API, the audit EntityType is the resource for this data. The audit table is read-only.

The audit table provides the data for the View Audit Summary displayed in the Power Platform admin center.

Make sure the calling user has the prvReadAuditSummary privilege to retrieve data from the table.

The following table summarizes important columns in the audit table.

SchemaName LogicalName DisplayName	Type	Description
`Action` `action` Event	Choice	Represents the event that caused the change. Learn more about actions.
`AttributeMask` `attributemask` Changed Field	Memo	When the change represents a change to record data, contains a comma-separated list of numbers that correspond to the AttributeMetadata.ColumnNumber for the columns that were changed. Note: Don't use this data. Instead, use the messages to retrieve change history.
`AuditId` `auditid` Record Id	Unique identifier	Identifies the primary key for the audit table.
`CallingUserId` `callinguserid` Calling User	Lookup	Identifies the calling user when impersonation is used for the operation; otherwise, null.
`CreatedOn` `createdon` Changed Date	DateTime	Identifies when the audit record was created, which is when the user operation took place.
`ObjectId` `objectid` Record	Lookup	Uniquely identifies the record that was audited.
`ObjectTypeCode` `objecttypecode` Entity	EntityName	Displays the logical name of the table referred to by the `objectid` column.
`Operation` `operation` Operation	Choice	Identifies the operation that created the audit record; one of four values: 1 = Create 2 = Update 3 = Delete 4 = Access
`UserId` `userid` Changed By	Lookup	Displays the ID of the user who changed the data.

Audit actions

Use Action Choices/Options to filter for specific events. The following tables categorize the events.

Table row events

These events capture changes to a record.

Value	Label	Message	Description
1	Create	`Create`	A record is created.
2	Update	`Update`	A record is updated.
3	Delete	`Delete`	A record is deleted.
12	Merge	`Merge`	A record is merged with another.
13	Assign	`Assign`	The `ownerid` column value for a user-owned table record is changed.
41	Set State	`SetState`	The `statecode` column value for a record is changed.

These events capture changes to record access when a record is shared.

Value	Label	Message	Description
14	Share	`GrantAccess`	A user is granted privileges to a record.
48	Modify Share	`ModifyAccess`	The privileges granted to a user are changed.
49	Unshare	`RevokeAccess`	A user's access to a record is removed.

Many-to-many relationship events

These events capture changes for many-to-many relationships.

Value	Label	Message	Description
33	Associate Entities	`Associate`	One or more records are associated with another.
34	Disassociate Entities	`Disassociate`	One or more records are disassociated from another.
53	Assign Role To Team	`Associate`	A security role is assigned to a team.
54	Remove Role From Team	`Disassociate`	A security role is removed from a team.
55	Assign Role To User	`Associate`	A security role is assigned to a user.
56	Remove Role From User	`Disassociate`	A security role is removed from a user.

User access events

These options capture the history of user access when user access auditing is enabled. The audit record for these events has an operation column value of 4.

Value	Label	Description
64	User Access via Web	User is accessing Dataverse using a model-driven app.
65	User Access via Web Services	User is accessing Dataverse with web services using a client other than a model-driven app.
112	User Access Audit Started	User access audit began.
113	User Access Audit Stopped	User access audit ended.

The Sample: Audit user access shows how to use these action options to audit user access.

Metadata change events

These events capture changes to table and column definitions as well as changes to the organization table.

Value	Label	Description
100	Delete Entity	User deleted a table.
101	Delete Attribute	User deleted a column.
102	Audit Change at Entity Level	User changed a table definition to enable or disable auditing.
103	Audit Change at Attribute Level	User changed a column definition to enable or disable auditing.
104	Audit Change at Org Level	User changed organization settings.

Audit change events

These events capture changes to audit settings.

Value	Label	Description
105	Entity Audit Started	Auditing was enabled for a table.
106	Attribute Audit Started	Auditing was enabled for a column.
107	Audit Enabled	Auditing was enabled for the organization.
108	Entity Audit Stopped	Auditing was disabled for a table.
109	Attribute Audit Stopped	Auditing was disabled for an attribute.
110	Audit Disabled	Auditing was disabled for a column.
111	Audit Log Deletion	An audit log was deleted.

Security role change events

These events capture changes to security roles.

Value	Label	Message	Description
57	Add Privileges to Role	`AddPrivilegesRole`	Privileges were added to a role.
58	Remove Privileges From Role	`RemovePrivilegeRole`	Privileges were removed from a role.
59	Replace Privileges In Role	`ReplacePrivilegesRole`	Privileges for a role were replaced.

Other actions

The remaining action options generally refer to auditable operations that apply to specific solutions, such as Dynamics 365 Sales, Customer Service, and Marketing.

The labels for these actions should align with an SdkMessage.Name value that represents the action. The specific operation may be a combination of the action name and a table. For example, an option with a value of 10 and the label Close should correspond to the CloseIncident or CloseQuote messages.

Audit table relationships

The audit table has only two many-to-one relationships with the systemuser table:

Relationship	Audit Table Lookup	Description
`lk_audit_userid`	`userid`	Relates the user to all the audit records created because of changes they made.
`lk_audit_callinguserid`	`callinguserid`	Relates the user to any of the audit records they created while impersonating another user.

You can use these relationships to filter audit data records created for a specific user.

The audit entity supports only one link entity in a query. Since only two relationships exist with the systemuser table, you can include data from either the callinguserid or userid columns, but not both at the same time.

You can't build queries using QueryExpression or FetchXml that join audit data with tables other than the two formal relationships that exist with the systemuser table.

Audit EntityType definition

With the Web API, use the audit EntityType resource to read data from the audit table. The following data is the audit EntityType definition from the Web API CSDL $metadata service document without annotations.

<EntityType Name="audit" BaseType="mscrm.crmbaseentity">
  <Key>
      <PropertyRef Name="auditid" />
  </Key>
  <Property Name="operation" Type="Edm.Int32" />
  <Property Name="attributemask" Type="Edm.String" Unicode="false" />
  <Property Name="action" Type="Edm.Int32" />
  <Property Name="useradditionalinfo" Type="Edm.String" Unicode="false" />
  <Property Name="createdon" Type="Edm.DateTimeOffset" />

  <Property Name="transactionid" Type="Edm.Guid" />
  <Property Name="auditid" Type="Edm.Guid" />
  <NavigationProperty Name="callinguserid" Type="mscrm.systemuser" 
    Nullable="false" Partner="lk_audit_callinguserid">
      <ReferentialConstraint Property="_callinguserid_value" 
        ReferencedProperty="systemuserid" />
  </NavigationProperty>
  <NavigationProperty Name="userid" Type="mscrm.systemuser" 
    Nullable="false" Partner="lk_audit_userid">
      <ReferentialConstraint Property="_userid_value" 
        ReferencedProperty="systemuserid" />
  </NavigationProperty>
</EntityType>

Note

The ChangeData Column isn't included in the Web API audit EntityType. Don't use this data. Instead, use the messages to retrieve audit change history.

Example: Find contact records deleted by a user

The following examples are queries that show the audit history for contact records deleted by a specific user.

Web API
SDK for .NET

Both of the following queries return the same response.

The following query filters on the _userid_value property of the audit record where the value matches <user id>.

Request:

GET [Organization URI]/api/data/v9.2/audits?$select=_objectid_value,objecttypecode,createdon,_userid_value&$orderby=createdon desc&$filter=operation eq 3 and objecttypecode eq 'contact' and _userid_value eq '<user id>'

Accept: application/json  
OData-MaxVersion: 4.0  
OData-Version: 4.0
If-None-Match: null
Prefer: odata.include-annotations="*"

The following query accesses the collection of audit records for a specific user with the lk_audit_userid collection-valued navigation property from the systemuser table, where the systemuserid value matches <user id>.

Request:

GET [Organization URI]/api/data/v9.2/systemusers(<user id>)/lk_audit_userid?$select=_objectid_value,objecttypecode,createdon,_userid_value&$orderby=createdon desc&$filter=operation eq 3 and objecttypecode eq 'contact'

Accept: application/json  
OData-MaxVersion: 4.0  
OData-Version: 4.0
If-None-Match: null
Prefer: odata.include-annotations="*"

Response:

HTTP/1.1 200 OK
Preference-Applied: odata.include-annotations="*"

{
  "@odata.context": "[Organization URI]/api/data/v9.2/$metadata#audits(_objectid_value,objecttypecode,createdon,_userid_value)",
  "@Microsoft.Dynamics.CRM.totalrecordcount": -1,
  "@Microsoft.Dynamics.CRM.totalrecordcountlimitexceeded": false,
  "value": [
    {
      "_objectid_value@Microsoft.Dynamics.CRM.lookuplogicalname": "contact",
      "_objectid_value": "0e76dc8a-41b5-ec11-983f-0022482bf046",

    },
    < Other results truncated for brevity>
  ]
}

The following two static methods show the number of contact records the specified user deleted. These queries use aggregation, so they aren't limited to 5,000 results. However, they're limited to the higher 50,000 record limit for aggregation.

ShowNumberContactsDeletedByUserQE uses QueryExpression.

/// <summary>
/// Shows the number of contacts deleted by a user.
/// </summary>
/// <param name="svc">IOrganizationService to use</param>
/// <param name="systemuserid">The user's id.</param>
static void ShowNumberContactsDeletedByUserQE(
    IOrganizationService svc,
    Guid systemuserid)
{
    var columnSet = new ColumnSet("auditid");

    //Adding Attribute expression to use aggregation
    columnSet
        .AttributeExpressions
        .Add(new XrmAttributeExpression(
            attributeName: "auditid",
            aggregateType: XrmAggregateType.Count,
            alias: "count"));

    var query =
    new QueryExpression(entityName: "audit")
    {
        ColumnSet = columnSet
    };

    query.Criteria.AddCondition(
        attributeName: "userid",
        conditionOperator: ConditionOperator.Equal,
        values: systemuserid);

    query.Criteria.AddCondition(
        attributeName: "operation",
        conditionOperator: ConditionOperator.Equal,
        values: 3);

    query.Criteria.AddCondition(
        attributeName: "objecttypecode",
        conditionOperator: ConditionOperator.Equal,
        values: "contact");

    EntityCollection records =
        svc.RetrieveMultiple(query);

    int number = (int)
        ((AliasedValue)records
        .Entities[0]["count"])
        .Value;

    Console.WriteLine(
        $"User has deleted {number} contact records");
}

Build queries with QueryExpression

ShowNumberContactsDeletedByUserFetchXml uses FetchExpression with a query composed using FetchXml.

/// <summary>
/// Shows the number of contacts deleted by a user.
/// </summary>
/// <param name="svc">IOrganizationService instance to use</param>
/// <param name="systemuserid">The user's id.</param>
static void ShowNumberContactsDeletedByUserFetchXml(
IOrganizationService svc,
Guid systemuserid)
{
    string fetchXml = $@"<fetch 
    distinct='false' 
    mapping='logical' 
    aggregate='true'>
<entity name='audit'>
    <attribute name='auditid' 
        aggregate='count' 
        alias='count' />
    <filter>
        <condition attribute='userid'

            operator='eq' 
            value='2' />
    </filter>

</fetch>";

    int number;

    try
    {
        EntityCollection records =
        svc.RetrieveMultiple(new FetchExpression(fetchXml));

        number = (int)
            ((AliasedValue)records
            .Entities[0]["count"])
            .Value;
    }
    catch (Exception)
    {
        throw;
    }
    Console.WriteLine(
        $"User has deleted {number} contact records");

Retrieve audit change history

You can use any of three messages to retrieve data changes that are audited.

Web API	SDK for .NET	Description
RetrieveAuditDetails Function	RetrieveAuditDetailsRequest Class>	Retrieve the full audit details from an audit record.
RetrieveAttributeChangeHistory Function	RetrieveAttributeChangeHistoryRequest Class	Retrieve the change history for a single column of an audited record.
RetrieveRecordChangeHistory Function	RetrieveRecordChangeHistoryRequest Class	Retrieve all audited data changes for a specific record.

To use these messages, make sure you have the prvReadRecordAuditHistory and prvReadAuditSummary privileges.

AuditDetail types

These messages provide more details that depend on the type of action. The details are implemented using types that are derived from a base AuditDetail type, as shown in the following table.

Web API	SDK for .NET	Description
AuditDetail ComplexType	AuditDetail Class	Displays the base type for the derived classes. Provides access to the audit record.
AttributeAuditDetail ComplexType	AttributeAuditDetail Class	Provides details when data changes occur for a record. Provides access to old values and new values. Returned by the following types of actions: - Table row events - Metadata change events - Audit change events
RelationshipAuditDetail ComplexType	RelationshipAuditDetail Class	Provides details when records are associated or disassociated using a many-to-many relationship. Provides the name of the relationship and a list of the records the operation changed. Returned by many-to-many relationship events.
RolePrivilegeAuditDetail ComplexType	RolePrivilegeAuditDetail Class	Provides details when the definitions of Security Role (Role) records change. Provides information about the old and new role privileges associated with the role. Returned by security role change events.
ShareAuditDetail ComplexType	ShareAuditDetail Class	Provides details when a record is shared or unshared or when the level of access to a shared record changes. Returned by record sharing events.
UserAccessAuditDetail ComplexType	UserAccessAuditDetail Class>	Provides details to track user access auditing. Provides details on the interval and access time. Returned by user access events.

Important

The Web API types listed earlier that inherit from AuditDetail ComplexType don't return the AuditRecord navigation property value they should inherit from AuditDetail. The SDK for .NET classes returns this data.
Large column values included in AttributeAuditDetail OldValue or NewValue properties such as Email.Description or Annotation are capped at 5KB or about 5,000 characters. A capped column value can be recognized by an ellipsis (…) at the end of the text; for example, "lorem ipsum, lorem ip…" Because the data is truncated, you can't use it to restore changes to these column values.

RetrieveAuditDetails message

Use this message to retrieve the audit details for a single audit record.

Web API
SDK for .NET

RetrieveAuditDetails is a function bound to the audit table. Include the Prefer: odata.include-annotations="*" request header to get formatted values.

The following example shows the AttributeAuditDetail ComplexType returned when the parentaccountid is set on an account record.

RetrieveAttributeChangeHistory Message

Use this message to retrieve a list of changes for a specific table column.

Use the PagingInfo parameter to control the number of records to return and move forward or backward through the pages. For subsequent requests, set the PagingInfo.PagingCookie property to the value returned by the AuditDetailCollection.PagingCookie.

Changes for this message are always AttributeAuditDetail types.

Web API
SDK for .NET

This example returns a single audited change history for the description column of an account table record.

RetrieveRecordChangeHistory Message

The RetrieveRecordChangeHistory message shows the history of data changes for the record indicated by the Target parameter.

The results of this message are commonly seen as the AttributeAuditDetail data displayed in model-driven apps when you select Related > Audit history. It shows the old values and the new values of the records, but it also returns RelationshipAuditDetail and ShareAuditDetail types.

This message can also be used with the systemuser and role tables to return RolePrivilegeAuditDetail and UserAccessAuditDetail types.

Web API
SDK for .NET

The following example returns just the first two of four changes to an account record.
