Greeting dear experts: EBS 12.1.3, issue:discount amount is calculated wrong after California withho

Invoice has the amount $23,000.00 and CA W/H line was created for $1610.00 on 9/12 so invoice amount is $21,390.00.

 

CA W/H was discarded on 9/18 as it was not needed.

Invoice amt is back to original amount of 23,000.00 and was paid on 9/19; vendors terms are 2% 15 Net 30 and we were able to take the discount. Oracle deducted 427.80 as the discount amount instead of 460.00. Oracle was still reading the invoice amount as 21,390.00 (23000.00 – 1610.00 ca w/h amount).
