• What is the cause and solution for SAP error message GL462 - Copying between local and global tables not supported ?

  The SAP error message GL462 ("Copying between local and global tables not supported") typically occurs in the context of ABAP programming when there is an attempt to copy data between local and global tables in a way that is not allowed by the SAP system. This error is often encountered when using certain ABAP statements or operations that involve data manipulation.
  Cause:
  The error arises due to the following reasons:
  
  Local vs. Global Tables: In ABAP, local tables are defined within a specific program or function module, while global tables are defined at the data dictionary level and can be accessed across different programs. The system does not allow direct copying of data between these two types of tables.
  Incorrect Use of ABAP Statements: The error can occur if you are using statements like INSERT, APPEND, or MODIFY inappropriately between local and global tables.
  
  Solution:
  To resolve the GL462 error, consider the following approaches:
  
  
  Use Intermediate Structures: Instead of trying to copy data directly between local and global tables, you can create an intermediate structure (or internal table) that holds the data temporarily. You can then transfer data from the local table to the intermediate structure and subsequently to the global table.
  Example:
  DATA: lt_local_table TYPE TABLE OF local_structure,
        lt_global_table TYPE TABLE OF global_structure.
  
  " Fill local table
  " ...
  
  " Transfer data to global table
  LOOP AT lt_local_table INTO DATA(ls_local).
    DATA(ls_global) = VALUE(global_structure)( field1 = ls_local-field1
                                              field2 = ls_local-field2 ).
    APPEND ls_global TO lt_global_table.
  ENDLOOP.
  
  
  Check Data Types: Ensure that the data types of the fields in the local and global tables are compatible. Mismatched data types can also lead to errors.
  
  
  Review ABAP Code: Go through the ABAP code to identify where the copying operation is taking place and modify it to adhere to the rules of local and global table handling.
  
  
  Use Function Modules: If applicable, consider using standard SAP function modules that are designed to handle data transfers between different types of tables.
  
  
  Related Information:
  
  ABAP Documentation: Review the official SAP ABAP documentation for more details on data types, internal tables, and the differences between local and global tables.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message.
  Community Forums: Engage with the SAP community forums or SAP support for additional insights and solutions from other developers who may have encountered the same issue.
  
  By following these guidelines, you should be able to resolve the GL462 error and ensure proper data handling in your ABAP programs.
