Hi SAP Experts,
My client has a requirement to make the tax code field as a required entry during transaction entry for customer accounts.
GL account is RECEIVABLE. This GL account is set as a reconciliation account for customers. I set the tax category in the GL account master data "+ Only output tax allowed" and posting without tax allowed "not ticked". I am hoping that not ticking the posting without tax allowed will solve the problem. However, upon testing, by simulating a transaction with a customer(receivable) entry and NOT populating the tax code, the system allowed me to post the transaction.
The only check that the system does is to check whether the tax code field is populated with an output tax code or not. If it is left blank it does not require the user/s to input the tax code.
