Costed_Flag = N in mtl_material_transactions

[AIMAM]

Hello,

In the Inventory module in oracle applications 11.5.10, a user complained that the customized report does not bring out the recently issued transactions. I have found that these records have the fields:

costed_flag = 'N' and request_id = 0
in mtl_material_transactions table.

I have launched the cost manager and the records were processed successfully. But again the problem occured and I don't know why; I have found that there are uncosted records in the above table.

What can I do to assure the problem does not raise again? what are the alternative to launching the cost manager;is it the on-line processing option? and how can i implement it?

Kindly note that we have only the following modules:
Inventory,Purchasing,General Ledger,Payables,Receivables,Cash Management,Fixed Assets, HRMS/payroll.

Thank you...
