Credit Line not created for Supplier Invoice in Projects

Hi,

System not generating the "Credit Line" for "Supplier Invoice" in Projects.

I have created Purchase Order through Requisition and Received into subinventories.

I have created Payable invoice and matched with Purchase Order Number.

Run Request "PRC: Interface Supplier Cost" to import supplier invoice from payable to projects and system generated "Debit Line".

Issue is:

After running the request "PRC: Generate Cost Accounting Events" system not generating the "Credit Line".

To generate the "Credit Line" what should I do ? Please help me.

Thank you very much.

Regards,

Ameer
