How To Fix ED351 - Source code of &1 contains modification parenthesis/es (line &2)

SAP Error Message - Details

• Message type: E = Error

• Message class: ED - ABAP/4 Editor messages

• Message number: 351

• Message text: Source code of &1 contains modification parenthesis/es (line &2)

What causes this issue?

The ABAP source code of &V1& contains modification parentheses.

System Response

Modification parentheses are comments as follows:
*{ INSERT
*} INSERT
*{ DELETE
*} DELETE
*{ REPLACE
*} REPLACE

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The modification assistant in ABAP Editor uses these parentheses in
customer systems to flag modified sections of source code in mod
ification mode. These help customers to insert their modifications again
after an upgrade.
If modification parentheses are delivered in source code from SAP (more
specifically, unpaired or nested parentheses), customers cannot benefit
from modification assistant functions. After an upgrade, customers can
no longer insert modifications automatically and it is also not possible
to make new modifications in ABAP source code using the modification
assistant.
This means modification parentheses cannot be added manually to ABAP
source code at SAP and then delivered in this source code.
The only exception to the delivery of source code with modification
parentheses are some industry solutions (or other special solutions)
that themselves are developed using the modification assistant at SAP.
In these cases, the modification parentheses are inserted automatically
by the modification assistant.

How to fix this error?

Remove (at the least) all unpaired and nested modification parentheses.
If the ABAP source code was not edited using the ABAP Editor
modification mode (the regular case at SAP), all modification
parentheses should be removed.
You can use the program RS_CHECK_MOD_BRACKETS_SAP to find all
modification parentheses in programs (even across a complete package).

• What is the cause and solution for SAP error message ED351 - Source code of &1 contains modification parenthesis/es (line &2) ?

  The SAP error message ED351 indicates that there are modification parentheses in the source code of a program or function module. This typically means that the code has been modified in a way that is not compliant with the standard SAP development guidelines, which can lead to issues during transport or execution.
  Cause:
  
  Modification Parentheses: The presence of modification parentheses in the source code indicates that the code has been modified directly in the SAP system. This is often done to customize the behavior of standard SAP programs or function modules.
  Transport Issues: If the modified code is part of a transport request, it may cause issues when trying to transport the changes to another system (e.g., from development to quality assurance or production).
  Incompatibility: The modifications may not be compatible with future updates or support packages from SAP, leading to potential problems during upgrades.
  
  Solution:
  
  Review Modifications: Check the source code for any modification parentheses. You can do this by navigating to the relevant program or function module in the ABAP editor (SE38 or SE80) and looking for the parentheses.
  Remove Modifications: If possible, consider removing the modifications or reverting to the standard version of the code. This can be done by using the transaction SE80 or SE38 to access the object and then using the "Restore" option if available.
  Use Enhancement Options: Instead of modifying standard code directly, consider using enhancement techniques provided by SAP, such as:
  
  User Exits
  Customer Exits
  BAdIs (Business Add-Ins)
  Enhancement Spots
  These methods allow you to extend or modify the functionality without directly changing the standard code.
  
  
  Consult Documentation: Review SAP notes and documentation related to the specific program or function module to understand the implications of the modifications and any recommended practices.
  Testing: After making changes, ensure thorough testing in a development or quality assurance environment to confirm that the functionality works as expected without the modifications.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or solutions related to the specific program or function module.
  Transport Management: Familiarize yourself with the SAP Transport Management System (TMS) to understand how transports work and how to handle modified objects.
  ABAP Development Guidelines: Review SAP's best practices for ABAP development to avoid direct modifications in the future.
  
  If you are unsure about how to proceed, it may be beneficial to consult with an experienced ABAP developer or SAP Basis consultant who can provide guidance based on your specific situation.
