Hi,

Inv. Discount Amount Excl. VAT and Invoice Discount % field is not editable in Sales order. I have tried and check in Sales & Receivable setup to make those fields enable. How can we enable it?

Please suggest.

You can not do this because these are calculated in Run Time. (They are Actually not even Table Fields but Run time Calculation Procedures)

These fields are automatically calculated based on Sales Lines and Sales & Receivables Setup. Manually editing them would break the business logic and can lead to inconsistencies in discount calculations.

Hello,

To enable the Inv. Discount Amount Excl. VAT and Invoice Discount % fields on a sales order in Business Central, follow this simple setup: Ensure Calc. Inv. Discount is turned on in Sales & Receivables Setup (this allows discounts to be calculated automatically).
Hope this answer will help you!

Hello,

The following configuration allows you to modify these values.

If disabled, it will allow to modify the fields in the sales order.

I hope I can help

In addition, you need to ensure that you are in edit mode and the Sales Order is in Open state.

Hope this helps as well.

Thanks.
