• What is the cause and solution for SAP error message FL331 - Import/export parameters cannot have the same names in pass by reference ?

  The SAP error message FL331 indicates that there is a conflict in the naming of import and export parameters in a function module or method when using "pass by reference." Specifically, it means that the import and export parameters cannot have the same name because it creates ambiguity in the data flow.
  
  Cause:
  The error occurs when:
  
  A function module or method is defined with both import and export parameters that share the same name.
  This can lead to confusion about which parameter is being referenced when the function is called, especially when passing data by reference.
  
  
  Solution:
  To resolve this error, you should:
  
  
  Rename Parameters: Ensure that the import and export parameters have unique names. This can be done by:
  
  Modifying the names of either the import or export parameters to ensure they are distinct.
  Using a naming convention that clearly differentiates between import and export parameters (e.g., prefixing import parameters with "i" and export parameters with "e").
