• What is the cause and solution for SAP error message FL332 - Generic types not allowed for import and export parameters of same name ?

  The SAP error message FL332: Generic types not allowed for import and export parameters of same name typically occurs in ABAP when you are trying to define a function module or method that has import and export parameters with the same name, and at least one of those parameters is defined as a generic type (like a table type or a structure).
  Cause:
  
  Parameter Naming Conflict: The error arises when you have both import and export parameters with the same name in a function module or method. SAP does not allow this because it can lead to ambiguity in how the parameters are handled.
  Generic Types: If any of the parameters are defined as generic types (e.g., TABLE, STRING, etc.), this restriction is enforced more strictly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Rename Parameters: Change the name of either the import or export parameter so that they do not conflict. For example, if you have an import parameter named DATA and an export parameter also named DATA, you could rename one to EXPORT_DATA or IMPORT_DATA.
  
  
  Avoid Generic Types: If possible, avoid using generic types for parameters that have the same name. Instead, define specific types for your parameters.
  
  
  Check Function Module/Method Definition: Review the definition of your function module or method to ensure that there are no naming conflicts and that the types are appropriately defined.
  
  
  Refactor Code: If the function module or method is complex, consider refactoring the code to simplify the parameter list and avoid conflicts.
