if we change a control code in existing material with revised tax code how it will impact

[VB12]

Hello All,

I want to change the control code from xyz to ABC in existing material, also need to change the tax rate for that material from 18%to 5% within date range 22.09.205 to 11.12.9999. How it will impact to the proforma invoices which is created before 22.09.2025. OR it is better to create a new material with new control code and revised tax rate.

Thanks and Regards

Changing the control code in the material master will only affect future transactions created after the change. Existing proforma invoices (created before 22.09.2025) will not be retroactively updated. They retain the control code and tax determination valid at the time of creation.

In SAP, tax rates are maintained in condition records, and not directly in the material master. If you maintain the new tax rate with validity starting 22.09.2025, then Proforma invoices created before 22.09.2025 will continue to show 18%. Proforma invoices created on or after 22.09.2025 will pick up the new 5% rate. SAP does not retroactively change tax rates in already created documents unless you cancel and recreate them.
