Using table parameter in SAP RFC Function module

When working with RFC enabled function modules in SAP, you should use a structure as line type for the table parameter. This approach ensures proper data handling and type safety when transferring tabular data between systems.

Creating the Dictionary Structure

First, you should declare a dictionary structure Z_MY_PARTS_DATA with a single field DESCRIPTION TYPE CGPL_TEXT2. This structure defines the layout of each row in your table parameter.

TYPES: BEGIN OF z_my_parts_data,
         description TYPE cgpl_text2,
       END OF z_my_parts_data.

Creating the Table Type

Next, declare a data dictionary table type Z_MY_PARTS_TABLE using this structure. This table type will serve as the parameter type in your RFC function module.

TYPES: z_my_parts_table TYPE TABLE OF z_my_parts_data.

Using the Table Type in Function Module

The final step is to use the table type in your Function module. In the function module interface, define the table parameter using the created table type ?

FUNCTION z_my_rfc_function.
*"----------------------------------------------------------------------
*"*"Tables"
*"  T_PARTS_DATA TYPE Z_MY_PARTS_TABLE
*"----------------------------------------------------------------------

  " Process the table data
  LOOP AT t_parts_data INTO DATA(wa_parts).
    " Your processing logic here
  ENDLOOP.

ENDFUNCTION.

Conclusion

Using structured table parameters in SAP RFC function modules provides a clean and type-safe approach for handling tabular data transfer between systems.
