Hi Rami,
You said that particular orders have been settled in October, but still you see they are considered for the November settlement. The reason is......
- Some postings have been done:
- If the order status is delivered: may be issue of material, confirmation, revaluation of activities or actual OH calculation
- If the order status is TECO: revaluation of activities or actual OH calculation
- Settlement type is FUL in the settlement rule for the orders: By this system is considering the order balances of October, in the settlement period of November also
So, you need to check the orders status and also whether any postings are done after settlement in the October period (use the transaction code KOB1 for easy analysis).
PRECAUTION:
In order to avoid these kind of situations, please when the order status is DLV or TECO, do settlement and check the order balance is ZERO (normally it will be) and once you make sure that no further activities (postings) are performed against the order, please make sure the order is CLOSED.
The concept of period lock (OKP1) suggested by Big Choi is the right one to avoid wrong postings to either closed periods or future periods.
But rarely wrong postings happen to closed periods. The major reason for this situation in your case would be revaluation of activities/prices if you are using it.
Regards...
Jose
