GATP Multilevel ATP
I am trying to configure MATP but I am facing some issues. I have created the check instructions to call production after product availability check and also created a PPM in APO with required input and output components. There are no rules defined. There is sufficient ATP for the components. I have defined the PP planning procedure as 5 , production heuristicss as sap_pp_03. The horizons have also been appropriately defined. However when i run a simulation check, the result screen doesn't even show the production column which is the usual case. I have set this up before and know how it works but I am clueless as to why it is not happoening now. Does it have to do something with the fact that I am using PPM and I am supposed to use PDS. I faced this issue where PPM created in APO is not recognized but then SAP document clearly says APO PPM. ANy thoughts to guide me?
1) Check the validity of teh PPM .
2) Check if any stock is confirming the requirement before executing the MATP if you have maintained 'product check' as first check in check instructions.
3) check the 'sched horizon for ATP tree structures' in the PPDS default settings in SPRO.
Hope this helps you.
