• What is the cause and solution for SAP error message TWBA034 - Do not create object in customer namespace ?

  The SAP error message TWBA034: Do not create object in customer namespace typically occurs when a user attempts to create or modify an object (like a program, function module, or class) in a namespace that is reserved for customer-specific developments.
