Table to link WBS Element and G/L account

Hi,

When creating PR with Acct Assignment Cat - as 'Project Make to Stock (Q)', WBS Element is mandatory. The system picks the G/L Account for WBS Element in transaction ME51N.

In my case, I need to know the table to which, I could give the WBS Element as input and get its G/L Account.

Thanks in Advance.

Regards,

Sunoj
