Ariba Invoice : Total Amount not getting added correctly

[dhinesh_thirugnanam]

Hi Team,

I am facing issue in Invoice for 1 supplier only. Where the Invoice total amount is not calculated correctly leaving the tax amount. By looking at the post processing payload the tax value(MWSBT :17.92)  is not added to the net price(BETRG:94.29).

In my below screenshot on the left side is the issue payload where Net Price + Tax is not calculated to the field "SUMME".

Right side screenshot is for different supplier payload where the Total amount is calculated correctly.

I could see a difference in 2 field's MSATZ and TXJCD value differs i.e  MSATZ = 19.000 & TXJCD = 3  / 1 . Is this causing any issue? What could be the reason?
