Issue:
Unexpected tax lines created on Payables invoice post upgrade.
The issue is observed with PO Matched, Migrated Invoices from 11i where the taxes were calculated in PO but the same are not on AP invoices.
Resolution:
This is a PO matched migrated invoice. For migrated invoices system does not calculate tax afresh. Only the existing tax lines were retained.
This AP invoice was matched to PO in 11i and there was tax calculated on PO lines which was not present on AP lines. When system upgraded this AP
invoice, it did not have any tax lines matching to PO tax.
invoice, it did not have any tax lines matching to PO tax.
Now, because system did not calculate tax afresh for migrated invoices in R12 and did not find the tax lines matching to PO tax lines, it created the zero amount reference tax lines by copying the details from PO data. These tax lines are created for variance calculation purpose.
