We are in the process of implementing S/4HANA for a customer. One of the question ftom our customer is why we need to have ACR for running tax reports. Our customer is already on R/3 and they are now implementing again with S/4HANA 2020 OP . The reports which are deemed as out of product support can still be run in our sandbox system and it is difficult to comprehend why is ACR even needed
Any guidance will be highly valuable.
