Hi again, Kbong!
You are correct in your first & second postings! I duplicated your complaint here with the sample data I was using, however - I have done some more testing here, and have more consistent results. I restored new sample data and tested posting retainage again. The end result was that QIP is posting properly, based on entering any amount instead of using the default retainage %. The correct amounts are posted through in AR if overriding the calculated retainage % by entering a flat amount.
I tested by entering 0.00% in the AR Company Profile's default retainage % as well as using a default of 5.43, then posted a few QIP invoices with retainage. I got the same results when entering & posting an invoice directly with AR or QIP.
FYI, when you post invoices in QIP, it is actually AR that is doing the posting routine, so the results (as you have noted) should be the same.
I would suggest doing a DIC and possibly reinstalling QIP. The newest release of QIP6.5A is 000201. This is compatible with AR 61-65A.
I cannot say why my older sample data was duplicating your issue, but I would look into this further. Please get back to us after trying the above suggestions and let us know what is happening.
Regards
