Hello to the community,
I am trying to get the prepostings on the customer invoice header to map on the M30 but it is not working.

I have the M103 setup with the c58 (mandatory preposting). the postings errors show that there is a missing value for M30 with C13 control type because I didn’t set it up correctly, not wanting data to get pulled from posting control but from preposting.

Does anyone by any chance know why values from preposting aren’t being pulled to M30 ?
Thank you
Tanya
