How To Fix ED350 - Source code contains unpaired or nested modification parentheses

SAP Error Message - Details

• Message type: E = Error

• Message class: ED - ABAP/4 Editor messages

• Message number: 350

• Message text: Source code contains unpaired or nested modification parentheses

What causes this issue?

The ABAP source code contains unpaired or nested 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.
In general, modification parentheses are not permitted in ABAP source
code from SAP. The only exception to this are some industry solutions
(or other special solutions) that themselves are developed using the
modification assistant at SAP.
In this case, paired modification parentheses are allowed in the source
code. Unpaired or nested modification parentheses cannot occur in this
scenario, since the modification assistant itself prevents them.

How to fix this error?

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

• What is the cause and solution for SAP error message ED350 - Source code contains unpaired or nested modification parentheses ?

  The SAP error message ED350 indicates that there is an issue with the source code in an ABAP program, specifically related to the use of modification parentheses. This error typically arises when there are unpaired or improperly nested parentheses in the code, which can lead to confusion in the program's logic and execution.
  Cause:
  
  Unpaired Parentheses: This occurs when there is an opening parenthesis ( without a corresponding closing parenthesis ).
  Nested Parentheses: This happens when parentheses are not properly nested, meaning that the order of opening and closing parentheses is incorrect.
  Syntax Errors: Other syntax errors in the code can also lead to this message, as the parser may misinterpret the structure of the code.
  
  Solution:
  
  Review the Code: Carefully examine the source code where the error is reported. Look for any instances of parentheses and ensure that each opening parenthesis has a corresponding closing parenthesis.
  Check Nesting: Ensure that parentheses are properly nested. For example, if you have an opening parenthesis inside another, make sure that the inner one is closed before the outer one.
  Use Code Formatting Tools: Utilize the formatting tools available in the ABAP editor to help identify mismatched parentheses. This can often highlight syntax issues.
  Debugging: If the error is not immediately apparent, consider using debugging techniques to step through the code and identify where the logic may be failing.
  Consult Documentation: If you are unsure about the correct syntax or structure, refer to the ABAP documentation or guidelines for proper coding practices.
  
  Related Information:
  
  ABAP Syntax Check: Use the syntax check feature in the ABAP editor (transaction SE38 or SE80) to identify and correct syntax errors.
  Code Review: If working in a team, consider having another developer review the code to catch any mistakes that may have been overlooked.
  SAP Notes: Check the SAP Support Portal for any relevant notes or updates that may address similar issues or provide additional guidance.
  
  By following these steps, you should be able to resolve the ED350 error and ensure that your ABAP code is correctly structured.
