We need to avoid rescheduling of Production order in APO

Question

Currently the production orders are created in ECC with reference to the plan orders transferred from APO. These orders are transferred back to APO as part of standard CIF. Since ECC is the owner of Production orders, we don’t want APO influencing any changes in production order. But there are situations when the APO is rescheduling the production order by automatically triggering heuristics after getting the changes in capacity from ECC via CIF. That is impacting with the schedule of orders already planned by business in ECC. One such known issue is when the capacity of resource has change during the time when order is scheduled. How should we avoid this?

Hi Anubrata,
Please check note 161028. This is the standard behaviour. If the SKU is X0 have to be planned by APO!
This note describes a modification proposal for the following purpose;
When a planned order is imported into R/3 via the interface, it is never scheduled in R/3 (detailed scheduling: esp. generation of capacity requirements).
This is the current design of APO <-> R/3 interface.
However, for such special requirements that the planned order should 'always' be scheduled, you can apply the following source code change.
This modification enables you to always automatically schedule the planned order that comes over the interface from APO for 'change' and 'create'. If capacity planning is activated, then also capacity requirements are determined in R/3.
This functionality only works for PP/DS planned orders and not for SNP planned orders. For SNP orders the SNP PPM will always be reexploded after a changed planned order is send back from R/3 to APO and then the order will be rescheduled in APO again.
Hope that can help you.
Thanks.
