Purchase requisition - G/L account (Urgent)

Hi All,

At the moment when purchase requisitions are generated by the WBS element, in the Account assignment tab of the requisition, i see G/L account field being filled by a particular G/L account no. I would like to know where in customizing, is this set. The G/L account which it is referring to is wrong & hence would like to change the same. Hope my problem is clear, await inputs.
