  The SAP error message TD639, which states "Function module could not find global ABAP variables," typically occurs when there is an issue with the function module trying to access global variables that are not defined or not available in the current context. This can happen for several reasons, including:
  Causes:
  
  Missing Global Variables: The global variables that the function module is trying to access may not be defined in the program or may have been deleted or renamed.
  Scope Issues: The function module may be called in a context where the global variables are not accessible due to scope limitations.
