• What is the cause and solution for SAP error message RSDHA156 - More than 1 registered output parameter of procedure '&1' ?

  The SAP error message RSDHA156, which states "More than 1 registered output parameter of procedure '&1'", typically occurs in the context of ABAP programming or when working with SAP BW (Business Warehouse) queries. This error indicates that a procedure (like a function module or a method) has been defined with multiple output parameters, but the system is unable to handle them correctly due to the way they are registered or called.
  Cause:
  
  Multiple Output Parameters: The procedure in question has more than one output parameter, which is not being handled correctly in the calling program or query.
  Incorrect Procedure Definition: The procedure may not be defined properly in the ABAP Dictionary or the function module might not be set up to handle multiple outputs.
  Query Design Issues: If this error arises in the context of a BW query, it may be due to the way the query is designed, particularly if it is trying to fetch data from a procedure with multiple outputs.
  
  Solution:
  
  Review Procedure Definition: Check the definition of the procedure (function module or method) to ensure that it is correctly defined with the appropriate output parameters. If it is intended to have multiple outputs, ensure that the calling program is set up to handle them.
  Modify the Calling Program: If you are calling this procedure from an ABAP program or a BW query, ensure that you are correctly handling the output parameters. You may need to adjust the code to accommodate multiple outputs.
  Use a Structure: If the procedure has multiple output parameters, consider returning them in a structure instead of individual parameters. This can simplify the handling of multiple outputs.
  Check Query Settings: If the error occurs in a BW query, review the query settings and ensure that it is correctly configured to handle the output from the procedure. You may need to adjust the query to align with the procedure's output.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to the procedure you are working with, as there may be known issues or additional configuration steps required.
