• What is the cause and solution for SAP error message FL813 - Structures with tables are not supported ?

  The SAP error message FL813, which states "Structures with tables are not supported," typically occurs when you are trying to use a structure that contains a table (internal table) in a context where it is not allowed. This can happen in various scenarios, such as when defining data elements, creating function modules, or working with certain types of data processing.
  Cause:
  
  Data Structure Definition: The error arises when a structure is defined to include an internal table. In SAP ABAP, structures can only contain elementary data types or other structures, but not internal tables.
  Function Module or BAPI: If you are trying to pass a structure with an internal table as a parameter to a function module or BAPI, it will trigger this error.
  Data Dictionary Objects: When creating or modifying data dictionary objects (like tables or views), if you attempt to include a table type within a structure, this error will occur.
  
  Solution:
  
  
  Redesign the Structure: Modify the structure to remove the internal table. Instead, you can create a separate internal table and use it alongside the structure.
  
  
  For example, if you have a structure defined as:
  TYPES: BEGIN OF my_structure,
           field1 TYPE char10,
           field2 TYPE char20,
           my_table TYPE TABLE OF my_table_type, " This will cause FL813
         END OF my_structure.
  Change it to:
  TYPES: BEGIN OF my_structure,
           field1 TYPE char10,
           field2 TYPE char20,
         END OF my_structure.
  
  DATA: my_table TYPE TABLE OF my_table_type.
  
  
  
  
  Use Nested Structures: If you need to group related data, consider using nested structures instead of including an internal table directly in the structure.
  
  
  Check Function Module/BAPI Parameters: If you are passing parameters to a function module or BAPI, ensure that you are not passing a structure that contains an internal table. Instead, pass the internal table separately.
  
  
  Review Data Dictionary Definitions: If you are working with data dictionary objects, ensure that you are not trying to define a structure that includes an internal table.
