BI invoice posting

Using the Flexible Invoice and Adjustment to enter additional items or services to bill to customer.  In some cases, the line item has a different GL subaccount than the Project so a task could be split to 2 GL subaccounts.

In all cases, the GL subaccount that is in the line item is not recognized and a GL subaccount from the project is used in posting.  The original GL subaccount is in the pjinvdet table but the GL reflects a different account.

Any suggestions?

Thanks,
