Re: Delta for ZFields in 2LIS_11_VAITM Data Source Not Getting Properly

Hi Frédéric,

Thanks for your valuable input. Allow me to share some additional information.

SAP Note 576886 - Change to user-defined fields not extracted is also relevant to refer to in this context. It has to do with the delta mechanism using a "before image" and "after image". This will trigger a delta for all fields known at that point in time.

The note suggests two solutions:

1. Add the required fields to the the SD communication structures using the Append method and use the LIS customer exits to fill the field;
2. Another way of adding user-defined fields to extract structures is to enhance the document tables, for example, VBAK, VBAP, VBEP, etc.

Best regards,

Sander
