Inclusive Tax Defaulting in Payables Open Interface

We have a Projects Intercompany Transaction where

1. IN AR, we are configured to have the amount as Inclusive TAx, this calculates correctly, takes the amount i.e 1000 and then calculates tax i.e. 900 base 10 tax = 1000 invoice total

2. IN AP, when we run the Payables Open Interface for Oracle Projects Inter-company, it is take the 1000 and calculating an extra 10 on top of that.  When i look at the interface table in AP, the amount_includes_tax_flag = N.  This is the issue, but I've tried a few things to default the flag to Y to no avail.

Any suggestions?

Thank you!
