It should be an internal table. typically indicates that a function or method in your ABAP program is expecting an internal table as input, but it is receiving data in a different format. This can occur in various contexts, such as when working with function modules, methods, or when passing data between different components in SAP.
  Cause:
  
  Incorrect Data Type: The variable being passed to the function or method is not defined as an internal table. It might be a single value, a structure, or another data type.
  Data Conversion Issues: There may be an issue with how the data is being populated or converted before being passed to the function.
  Function Module/Method Signature: The function module or method you are calling has a specific signature that requires an internal table, and the provided argument does not match this requirement.
  
  Solution:
  
  Check Data Type: Ensure that the variable you are passing is indeed defined as an internal table. You can do this by checking the data declaration in your ABAP code.
  DATA: lt_table TYPE TABLE OF your_structure.

  Review Function Module/Method Documentation: Check the documentation for the function module or method you are calling to ensure you are passing the correct parameters. Make sure you are using the correct types and structures as expected.
  Debugging: Use the ABAP debugger to inspect the values and types of the variables being passed to the function/module. This can help you identify where the mismatch is occurring.
