How to Add Custom Field in SAP Standard Report ME5A & ME2N

In SAP implementation, it is often necessary to add custom fields in standard reports such as ME5A (Purchase Requisition List) and ME2N (Purchase Order List). This guide explains step-by-step how to enhance these reports using append structure and BADI ME_CHANGE_OUTTAB_CUS.

Step 1: Append Structure

• For report ME5A: append structure in MEREP_OUTTAB_EBAN.
• For report ME2N: append structure in MEREP_OUTTAB_PURCHDOC.

Step 2: Implement BADI ME_CHANGE_OUTTAB_CUS

After appending the structure, create a new implementation in BADI ME_CHANGE_OUTTAB_CUS to populate the values of the custom fields. Custom logic should be added in the method IF_EX_ME_CHANGE_OUTTAB_CUS~FILL_OUTTAB.

ABAP Code Example

METHOD if_ex_me_change_outtab_cus~fill_outtab.
  FIELD-SYMBOLS:
    <fs_tabrel> TYPE merep_outtab_purchdoc,
    <fs_eban>   TYPE merep_outtab_eban.

  CASE im_struct_name.
    WHEN 'MEREP_OUTTAB_PURCHDOC'. "PO
      " --- custom logic for Purchase Order report (ME2N) ---
      ...

    WHEN 'MEREP_OUTTAB_EBAN'. "PR
      " --- custom logic for Purchase Requisition report (ME5A) ---
      ...
  ENDCASE.
ENDMETHOD.
  

Best Practices

• Always use append structure to keep SAP standard intact.
• Ensure your BADI implementation only fills relevant fields.
• Use SELECT SINGLE or caching to avoid performance issues.

Conclusion

By using append structure and BADI ME_CHANGE_OUTTAB_CUS, you can add custom fields to standard reports ME5A and ME2N without modifying SAP standard programs. This method is safe, flexible, and recommended by SAP best practices.
