• What is the cause and solution for SAP error message LTR_MODEL_APPL153 - The parameter's table type &1 actually is not an internal table type ?

  The SAP error message LTR_MODEL_APPL153 indicates that there is an issue with the type of a parameter being passed to a function or method in your ABAP code. Specifically, it suggests that the parameter's table type is not recognized as an internal table type, which is required for the operation being performed.
  Cause:
  
  Incorrect Data Type: The parameter being passed is not defined as an internal table type. This could happen if the parameter is defined as a standard data type (like a single value) instead of an internal table.
  Type Mismatch: The function or method expects a specific internal table type, but the provided parameter does not match this expectation.
  Incorrect Declaration: The internal table might not be declared properly in the ABAP program, leading to the system not recognizing it as an internal table.
  
  Solution:
  
  Check Parameter Declaration: Ensure that the parameter being passed is declared as an internal table. For example, it should be declared using the TYPES statement or as a DATA statement with the appropriate table type.
  TYPES: BEGIN OF ty_example,
           field1 TYPE string,
           field2 TYPE i,
         END OF ty_example.
  DATA: lt_example TYPE TABLE OF ty_example.
  
  Verify Function/Method Signature: Check the signature of the function or method you are calling to ensure that you are passing the correct type of parameter. If it expects an internal table, make sure you are passing one.
  Use Correct Table Type: If the function requires a specific internal table type, ensure that you are using that type. You may need to create a new type or use an existing one that matches the expected structure.
  Debugging: If you are unsure about the types being used, you can use the ABAP debugger to inspect the types of the variables at runtime to ensure they match the expected types.
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with ABAP data types, especially internal tables, which are crucial for handling collections of data.
  Function Module Documentation: Review the documentation for the function module or method you are using to understand the expected parameter types.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function or method you are using, as there may be patches or updates that address similar issues.
  
  By following these steps, you should be able to resolve the error message LTR_MODEL_APPL153 and ensure that your ABAP code is functioning correctly.
