ARXTWMAI Transactions form

Symptoms

Tax is calculated correct for generated Invoices / Credit Memos / Debit Memos
Modifying / Overriding / Editing the following fields in Line Items window in Transactions form causes re-computation of Tax and it may be wrong :
Description ,Quantity,Unit Price,UoM

Tax may be recalculated to double than expected value
It happens for Inclusive Tax or Tax Groups

Steps to reproduce
1. Query an Invoice in Transactions form
2. Click Line Items
3. Change the description
4. Tax Amount is doubled / incorrect.

Tax Debug log file may show the following info for a Line with Amount = 500 and Tax rate is 10% inclusive:
arp_process_tax.set_line_flags()+
l_old_line_rec.extended_amount = 454.55
l_old_line_rec.gross_extended_amount = 500
p_line_rec.extended_amount = 500 **
**The last line shows that amount taken for re-computation is again 500 and not 454.55 which will result in wrong tax.

Changes

The issue may be reproduced after upgrade to 11.5.10 or 11i.AR.M or 11i.AR.N
The Issue may reproduce when patch for <Bug: 3671235> has been applied on any release
