Posted on by MartinVargas

Hello community, I present my case to you. On the Purchase Orders page, when requesting approval and approving it, the Total Amount Incl. VAT is modified. I need to find the trigger or condition that updates this amount since I am altering it at the code level.

Normally, since the purchase order is disapproved, it should be shown with these calculations:

any ideas?

Hi, as far as I know, the following methods are mainly used, you can investigate in depth.

table 38 "Purchase Header"

page 54 "Purchase Order Subform"

Hope this helps.

Thanks.

Total is not the problem, seems the problem is from field IVA total (MXN).
So check why the IVA amount is changing - in Your example from 160 to 90.

I assume it is the VAT. So check if the original VAT Bus. and Prod. posting group in the line and VAT percentage, and check what are they after the approval. Do they change or stay the same?

Also might be it is localization issue, so please let us know which localization You are using is it Mexico or something else?

KasparsSemjonovs Yes, just as I am altering the Total Amount based on the withholding (70) on the subtraction, the amount remains at 1090. The base calculates the VAT: 1090 - 1000 (which is the amount without VAT) so the VAT is 90.

My doubt is that it recalculates the total amount when the purchase order is approved.
