CRMProcessController.RetrieveCompletedSteps Method
The RetrieveCompletedSteps method retrieves all of the completed steps.
Syntax
[Visual Basic .NET]
Public Function RetrieveCompletedSteps(
ByVal Caller As CUserAuth,
ByVal ProcessInstanceId As String,
ByVal ColumnSetXML As String
) As String
[C#]
public string RetrieveCompletedSteps(
CUserAuth Caller,
string ProcessInstanceId,
string ColumnSetXML
);
[C++]
public: String* RetrieveCompletedSteps(
CUserAuth* Caller,
String* ProcessInstanceId,
String* ColumnSetXML
);
Parameters
Caller
Specifies the identity of the caller. To perform this action, the caller must have the prvReadWorkflowProcessInstance privilege and access rights on the objects to be retrieved. See CUserAuth.
ProcessInstanceId
Specifies the ID of the process instance to be retrieved.
ColumnSetXML
Specifies an XML string describing the set of columns to be retrieved. Passing an empty string or null returns all columns (Nothing or "" in VB .NET). You can find the valid column names in wfstep.xsd. See also ColumnSetXML Schema.
Return Value
Returns a String type that specifies the XML data containing the set of steps. The fields that are returned depend on what fields are specified in the ColumnSetXML parameter. This XML string is in the format
<wfsteps> + wfstep1..N + </wfsteps>
where the XML schema for each step is described by wfstep.xsd.
Remarks
The XML string returned from this method may contain multiple objects. If no objects are returned the method simply returns an XML document for the object type with no data.
The XML string returned from this method does not contain elements for fields where the value is null or contains empty strings. This improves performance by not sending more XML data than is necessary from the server to the client.
If there is an error, SOAP throws an exception and the error message is reported in System.Web.Services.Protocols.SoapException.Detail.OuterXml.
All IDs passed to the platform are GUIDs wrapped in braces. For example: {6522D89A-A752-4455-A2B0-51494C6957C3}
Example
[C#]
// strServer should be set with the name of the platform Web server
string strServer = "myservername";
// virtualDirectory should be set with the name of the Microsoft CRM
// virtual directory on the platform Web server
string virtualDirectory = "mscrmservices";
string strDir = "https://" + strServer + "/" + virtualDirectory + "/";
// BizUser proxy object
Microsoft.Crm.Platform.Proxy.BizUser bizUser = new Microsoft.Crm.Platform.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";
// CRMProcessController proxy object
Microsoft.Crm.Platform.Proxy.CRMProcessController processcontroller = new Microsoft.Crm.Platform.Proxy.CRMProcessController();
processcontroller.Credentials = System.Net.CredentialCache.DefaultCredentials;
processcontroller.Url = strDir + "CRMProcessController.srf";
string strErrorMsg;
try
{

string strProcessInstanceId = "{A8CB383D-C9F2-2344-34KE-4A59F7569432}";
// Set up the columns that you want to retrieve
string strColumnSetXml = "<columnset>";
strColumnSetXml += "<column>name</column>";
strColumnSetXml += "<column>description</column>";
strColumnSetXml += "<column>stepcode</column>";
strColumnSetXml += "</columnset>";
string strStepsXml = processcontroller.RetrieveCompletedSteps (userAuth, strProcessInstanceId, strColumnSetXml);
}
catch (System.Web.Services.Protocols.SoapException err)
{
// Process the platform error here
strErrorMsg = ("ErrorMessage: " + err.Message + " " + err.Detail.OuterXml + " Source: " + err.Source );
}
catch (Exception err)
{
// Process other errors here
strErrorMsg = ("ErrorMessage: " + err.Message );
