• What is the cause and solution for SAP error message TD121 - Window & already exists ?

  The SAP error message TD121, which states "Window & already exists," typically occurs when there is an attempt to create a window (such as a print window or a dialog window) that already exists in the system. This can happen in various contexts, such as when configuring print settings or defining output formats.
