Hi,
PMDC program is using to update the master data changes in Trade promotions or any Marketing objects, like Product category, group, List price etc changes.
It had a limitation while running, if Promotion is already released and the start of the Promotion is in the past, in that case this program will not refresh the Promotions by updating the changed master data.
We have screen selection option to look back number of days to check Master data changes as well only Price changes.
@ Erik - Can you please give the error details, what exactly you are getting.
Regards
Naren..
