Step 3: Transform the X12 850 PO Message to the ORDERS05 Message
Important
Microsoft Azure BizTalk Services (MABS) is being retired, and replaced with Azure Logic Apps. If you currently use MABS, then Move from BizTalk Services to Logic Appsprovides some guidance on moving your integration solutions to Logic Apps.
If you're brand new to Logic Apps, then we suggest getting started here:
-
Create your first logic app, or quickly get started using a pre-built template
-
View all the available connectors you can use in your logic apps
Both the X12 850 schemas and ORDERS05 schemas are pretty complex and require functional expertise in the respective domains to understand and create maps between the two schemas. While you already generated the schema for ORDERS05 IDOC, you can get the schema for X12 PO message (X12_00401_850.xsd) from the MicrosoftEdiXSDTemplates.zip that you previously downloaded and extracted. You must add the X12_00401_850.xsd schema to the SAPIntegration project.
Creating a Transform between the X12 850 PO and ORDERS05 PO requires functional domain knowledge of both the X12 schema and the ORDERS05 schema. Only then one can identify which field in the X12 schema maps to which field in the ORDERS05 schema. In this tutorial, we do not get into such details and instead use an existing Transform (AzureTransformations.trfm) between these two schemas. This Transform is available in the SAPIntegration project that you can download from the MSDN Code Gallery.
To include the transform in the BizTalk Service project, right-click the project name, select Add, select Existing Items, and then navigate to the location where you downloaded the SAPIntegration sample from the MSDN Code Gallery. Select the AzureTransformations.trfm and then select Add.
