Purchase order modification

david_escofettrenado — Wed, 29 Jul 2009 09:25:42 GMT

Hi,

We are using this functionaly:

We change purchase requistiion quantity with BAPI BAPI_REQUISITION_CHANGE.

If modification is correct we are doing a BAPI_TRANSACTION_COMMIT with WAIT and also we modify purchase order quantity with BAPI BAPI_PO_CHANGE.

If purchase order modification is correct we are doing a BAPI_TRANSACTION_COMMIT with WAIT.

Sometimes occurs that if a change is done with BAPI_REQUISITION_CHANGE correctly and we are doing the correspondant changes to purchase order BAPI_PO_CHANGE, this bapi give error ME 006 (User alredy processing requisition).

How it is possible if we have done a commit and wait?

How can we solve this problem?

Best regards¡¡¡

Hi,

The object is still locked when you try to change with BAPI_PO_CHANGE and thats the reason you are getting the error message.

Before calling BAPI_PO_CHANGE, check whether the object is unlocked, you can do that with deque function .

HI,

Try using FM : ENQUE_SLEEP for wait process.

Actually sometimes, due to some database constraints, process takes time to save document.

SO better to give 5 seconds delay for that.

CALL FUNCTION 'ENQUE_SLEEP'

EXPORTING

SECONDS = '5'

EXCEPTIONS

SYSTEM_FAILURE = 1

OTHERS = 2.

Regds,

Anil
