Commitment in Purchase contracts and purchase order

Question

Hi,
We are loading contract through LSMW. As account assignment we are just passing the cost center and the account is configure in OKB9.  However for some contract the flag is set in items affect commitments and the wrong account is determine. I want to know if this behavior is normal and why? How do you know how commitment is set up in the system?
I have also seen that for some purchase order there are commitment lines that have been created in table COOI. Those pruchase order has been created through idoc and here again we do set the commitment flag.
Thank you for your help

Hi,
Please consider that purchasing documents which do not have facility of GR, can not create commitment, hence commitment is not available for contracts.
In case you want PR commitment to be adjusted against PO, please ensure that along with contract, PR number should also be filled in PO.Here I mean for EKPO-BANFN should be filled in PO then commitment would not be double.
Case 1 with contract:
When you post Purchase requisition.
- Purchase requisition updates commitment.
- You see purchase requisition amount in the report S_ALR_87013558.
When you post Contract with reference to the Purchase Requistion:
- Purchase requistion commitment stays as it is.
- Contract doesn't update the commitment.
- You see purchase requisition in the reprot S_ALR_87013558.
When you post a purchase order with reference to contract:
- Purchase requistion commitment stays as it is.
- Contract doesn't update the commitment,
   When PO posted with reference to contract, there is no   commitment reduction for the contract either.
- Purchase Order commitment is updated.
- You see purchase requisition and order in the report S_ALR_87013558.
Case 2 without contract:
When you post Purchase requisition.
- Purchase requisition updates commitment.
- You see purchase requisition amount in the reprot S_ALR_87013558.
When you post a purchase order with reference to requisition:
- Purchase requistion commitment is reduced by PO posting
- purchase order commitment is updated.
- You see only the purchase order amount in the report S_ALR_87013558.
The  attached note 151451 describes also the system behaviour.
