I need help creating a simple user exit to populate fields I added to a datasource.
Generic Datasource uses a view that contains one field belnr from table RBKP.
I enhanced the structure with append to add fields a, b, c.
Data for a,b,c has to come from table EKBE based on the common field belnr AND the following conditions:
EKBE-c = b and
EKBE-C = 2
If the value of blrn doesn exist in ekbe, no need to populate additional fields.
Please help create the user exit. Not an include I have to use a program.
Thanks in advance.
