Dear,
You might want to reconcile data from source. I am not sure what is your source here? Key information is following:
- Material which is tab in your case.
- Duration which is one month
- Customer type is ship-to (In ECC, ship-to is associated with SH type)
- Ordered quantity
First try to match data using above characteristics and key figure with your base info provider and what is in your source. Then you might want to show only MTD data restricting with other characteristics which is material tab and customer type as ship-to.
Thanks & Regards,
M
