This topic describes the different ways that you can update data by using Application Integration Framework (AIF). Many of the document services that are included with Microsoft Dynamics AX support the modification of data by using the update service operation. For more information about document services included with Microsoft Dynamics AX, see Standard Document Services.
AIF supports two types of updates:
Full update – This type of update replaces the existing document by using the new one. All the data submitted to AIF is considered to be the full document and all fields in the database tables are replaced with the field values from the submitted document. If there are fields in the corresponding tables that are not in the submitted data, those table fields are cleared according to the rules for the data type of the field. For more information about full updates, see Full Update With AIF and Walkthrough: Updating Data with AIF (Full Update).
Partial update – This type of update modifies the existing document. Only the fields that are submitted to AIF are modified in the corresponding database tables. Fields for which no new values have been submitted retain their original values, unless their values have been reset to a default value because a related field was modified. For more information, see Partial Update With AIF.
Calling the Update Service Operation
To update data through AIF, you must call the update service operation for the document service. For example, if you want to update a sales order, call the SalesSalesOrderService.update service operation. This service operation takes two parameters.
_entityKeyList – A list of one or more entity key values, or IDs, for the documents to be updated.
_salesSalesOrder – The document that contains the sales order data that updates the sales order in the database.
Each of these parameters must be serialized to XML that complies with the document and related schemas. These schemas specify the content and structure of the service operation parameters. For more information about the schemas used in AIF, see Messages and transforms in AIF and Document Schemas.
In some cases, you can view the fields that can be updated in a form that corresponds to a particular document. There is not an exact mapping between the way that fields are used in the form and in the document service, but frequently the correspondence is very close. For example, to see the fields involved with the Sales Order service, you can view the Sales order form. Click Accounts receivable > Common > Sales orders > All sales orders.
