an Input script is not working, the first question to ask would
be: If I were to do these steps in standard SAP with same data,
what would happen?
on Input script Trace from Options->Trace auto processing on
GuiXT window. The trace window will show execution steps of an
input script. This trace also outputs the values of GuiXT
on visible auto processing from Options->Visible auto
processing. Now, any input script will run in a single step
mode. GuiXT will process the screen block and wait for Enter to
be pressed by user to execute Enter "XXX" command.
