SAP supports the product, AMS supports your build
Raise a ticket with SAP about a pricing condition that calculates the wrong VAT and you will be told, correctly, that standard code is working as designed. Your condition tables, your access sequences, your Z routine and your interface to the tax engine are yours.
- Configuration, custom ABAP, interfaces and roles covered by name
- SAP notes raised and chased on your behalf when the fault is standard
- One accountable queue, so nothing sits between two vendors
