  The SAP error message TFW_API039 indicates that a function module (in this case, represented by &1) was called without any input tables being requested. This typically occurs in the context of using the SAP Transformation Framework (TFW) or when working with data transfer processes.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Incorrect Function Module Call: The function module is being called without the necessary input parameters or tables that it expects.
  Configuration Issues: The configuration for the data transfer or transformation process may not be set up correctly, leading to the absence of required input tables.
  Data Source Issues: The data source from which the function module is supposed to retrieve data may not be correctly defined or may not contain any data.
  
  Solution:
  To resolve the TFW_API039 error, you can take the following steps:
  
  
  Check Function Module Parameters:
  
  Review the function module's documentation to understand what input tables or parameters are required.

  Debugging:

  Look for any conditions or filters that might be preventing data from being passed to the function module.
