Mismatched data for "Created By" in generated Purchase Requisitions

Hi,

Just wanted to ask question to all gurus that, I see some mismatched data for ‘created by’ for system generated Purchase requisitions. As if I do MRP run using MD40(MPS scheduling run) then system is showing PR created by 'MRP controller' but if I run MRP using MD41(single item multi level), then system is showing the user ids name(the person on whose id MRP run is executed) is showing in the PR.

As both the MRP runs being executed in the same user id, then there should not be such kind of diffrent data. Due to this mismathced data we are gettting some difficulties in the reporting. 

Thanks in advance.

Regards

Amit
