• What is the cause and solution for SAP error message C$721 - Function &: The table parameter & does not have the correct structure ?

  The SAP error message C$721 indicates that there is a mismatch between the expected structure of a table parameter and the actual structure being passed to a function module or method. This error typically occurs in ABAP programming when the data structure of the table being passed does not match the definition expected by the function.
  Cause:
  
  Mismatched Structure: The most common cause is that the structure of the internal table being passed does not match the expected structure defined in the function module or method.
  Field Names or Types: The field names or data types in the internal table may differ from those defined in the function module.
  Missing Fields: The internal table may be missing required fields that the function expects.
  Incorrect Table Type: The type of the internal table (standard, sorted, hashed) may not match what the function expects.
  
  Solution:
  
  
  Check Function Module/Method Definition: Review the definition of the function module or method to understand the expected structure of the table parameter. You can do this by using transaction SE37 (for function modules) or SE80 (for classes and methods).
  
  
  Compare Structures: Use transaction SE11 to compare the structure of your internal table with the expected structure. Ensure that all fields match in terms of name, type, and length.
  
  
  Adjust Internal Table: Modify your internal table to ensure it matches the expected structure. This may involve:
  
  Adding missing fields.
  Renaming fields to match.
  Changing data types to ensure compatibility.
  
  
  
  Use Data Dictionary: If the function module expects a specific data dictionary structure, ensure that you are using the correct type. You can create a new internal table based on the expected structure using the DATA statement.
  
  
  Debugging: If you are unsure about the structure, you can set breakpoints in the function module to inspect the incoming parameters and see what structure is being passed.
