Modify the native behavior of tax calculation in BC

(0) ShareShare
ReportReport
Posted on by PHT80 40

I need to modify the native behavior of tax calculation in BC. I am developing on BC16 OnPremise and "VAT calculation type" is "Sales Tax".

Basically I need to be able to add or remove tax codes at runtime and not by setup. In the same way, also modify the VAT % (percentage applied to the tax code).

 I've been reviewing and debugging the source code on the following objects, but I can't determine where to extend my code. 

  • codeunit 80 Sales-Post -> procedure onrun() -> checktotalincoiceamount()
  • tabla 37 Sales Line -> procedure CalcVATAmountLines()
  • tabla 290 VAT Amount Line. procedure updatelines()
  • codeunit 398 Sales Tax Calculate -> procedure CalcualteTax()

 

Is it possible to modify the native tax behavior in BC?

 

Thanks.

Kindest regards.

    Hello,

    We currently do not have dedicated Dev support via the Dynamics 365 Business Central forums, but I wanted to provide you some additional resources to assist.  If you need assistance with debugging or coding I would recommend discussing this on one of our communities.

    I will open this up to the community in case they have something to add.

    Thanks.
