[US][Codeunit][6785][Withholding Tax Mgmt.][OnBeforeInsertWithholdingTax in InsertVendInvoiceWithholdingTax

[rthorud]

Why do you need this change?

Need to calculate AmountVAT based on fixed fee per quantity and unit of measure than percent of total (e.g. 1 cent per bushel of grain). Current code only allows one way of calculation the withholding amount.

Describe the request

We need an integration event added at then end of the procedure InsertVendInvoiceWithholdingTax right before the call to InsertWithholdingTax(TType::Purchase);. The event must pass a reference to the AmountVAT variable and the Purchase Invoice Header:

[IntegrationEvent(false,false)]
local procedure OnBeforeInsertWithholdingTax(var AmountVAT: Decinal; PurchInvHeader: Record "Purchase Invoice Header");
begin
end;

There are no existing events in this extension.

There are no expected impacts to performance, data sensitivity, or interactions or conflicts with other extensions.

Hi @rthorud,

Thank you for your extensibility request. To help us process it efficiently, please update the issue to include the required information.

📚 Extensibility Guidelines

Missing Information:

• IsHandled justification: Explain why bypassing the standard logic with an IsHandled event is necessary instead of using a regular event to adjust AmountVAT before InsertWithholdingTax(TType::Purchase);
• Alternatives evaluated: Describe which existing events or alternative extension points were considered and why they are insufficient for this scenario
• Impact considerations: Include brief considerations for performance impact, data sensitivity, and multi-extension interaction or conflict risk

Please update the issue with the missing details. We'll automatically re-analyze once updated.
