Using Append field of generic DataSource for Time Stamp as Delta-Specific Field

Hi experts,

I want to use an append field (AEDAT) of a generic DataSource as Delta-Specific Field.

In a first step I had create a generic DataSource based on the table VBPA (SD Partner).

In a second step I have enhanced the generic extract structure of my DataSource ZVBPA with the date field "AEDAT" (Changed On)

In a small cmod coding I fill the new field "AEDAT" with the help of the table "CDHDR" (Change document header) as source to read the newest change date of the sales document.

Finally, now I want to use the append field (AEDAT) of my generic DataSource as Delta-Specific Field (RSO2) to use the delta mechanism and load the partner roles to the sales document.

Any ideas?

Many thanks in advance!

Best regards,

Michael
