  The SAP error message FL387, which states "Type &1 is not a table type," typically occurs when there is an attempt to use a data type that is not defined as a table type in the context of ABAP programming or when working with function modules, methods, or data declarations.
  Cause:
  
  Incorrect Data Type: The variable or parameter being referenced is not defined as a table type. This can happen if you are trying to pass a structure or a simple data type where a table type is expected.
  Typographical Error: There may be a typo in the name of the table type being referenced.
  Missing Declaration: The table type may not be declared in the program or the relevant context.
  Scope Issues: The table type might be defined in a different context (like a different program or class) and is not accessible in the current context.
  
  Solution:
  
  
  Check Data Type Declaration: Ensure that the variable or parameter you are using is declared as a table type. You can do this by checking the data dictionary (SE11) for the correct table type.
  Example:
  TYPES: BEGIN OF ty_table,
           field1 TYPE string,
           field2 TYPE i,
         END OF ty_table.
  TYPES: tt_table TYPE TABLE OF ty_table.
  DATA: lt_table TYPE tt_table.
  
  
  Correct Typographical Errors: Verify that the name of the table type is spelled correctly and matches the definition in the data dictionary.
  
  
  Declare the Table Type: If the table type is not declared, you need to declare it in your program or include it from a relevant include file.
  
  
  Check Scope: If the table type is defined in another program or class, ensure that it is accessible in the current context. You may need to use the appropriate namespace or include the relevant definitions.
  
  
  Use the Correct Function Module/Method: If you are calling a function module or method, ensure that the parameters you are passing match the expected types defined in the interface.
