Use the Generate SAP IDoc Prepare Transformation Wizard to create an SAP/ALE IDoc Prepare transformation. The wizard lets you import basic or extended IDoc type metadata.
When you create an SAP/ALE IDoc Prepare transformation, you can import the IDoc metadata in the following ways:
From file.
Use to import the metadata for the IDocs in the SAP/ALE IDoc Prepare transformation from a metadata file. For information about generating IDoc metadata, see Generating IDoc Metadata to File for Import.
When you import the IDoc metadata from file, SAP converts numeric datatypes in the IDoc metadata to CHAR. When you create or edit the transformation, apply the appropriate transformation datatypes to the ports that have numeric datatypes in SAP.
Connect to SAP.
Use to import the IDoc metadata from the SAP system to use in the transformation. The PowerCenter Integration Service can validate the input data you pass into the transformation.
