How To Fix XW220 - Checksum is invalid for segment "&1"

SAP Error Message - Details

• Message type: E = Error

• Message class: XW - DART - Data Retention Tool

• Message number: 220

• Message text: Checksum is invalid for segment "&1"

What causes this issue?

The data checksum for segment &V1& is invalid. This can have the
following causes:
The data in the extract file has been altered after the file was
written.
If the source data is in Unicode, but the extract is written in
non-Unicode format, a character format conversion takes place
automatically when writing a record to the extract file. The checksum is
calculated before this conversion, and as a result there will be a
checksum error if there is any character whose representation changes as
an effect of the conversion.
Note: If the source data is in UTF-8 format, a subset of common ASCII
characters is represented identically in ASCII and UTF 8. If the data
consists of only such characters, then there will be no checksum errors.
Unicode characters that cannot be converted to an equivalent ASCII
characters are converted to "#".

System Response

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

How to fix this error?

If the current extract is a copy of an original extract, use the
original data. If the extract was retrieved from the archive, retrieve
the extract again.
You can check the extract integrity with program RTXWCHK3
<DS:REPO.RTXWCHK3>(execute program)</>.
In the <DS:TRAN.FTWP>extract configuration</> you can set up DART to
write extracts in Unicode. This will avoid any data conversions.

• What is the cause and solution for SAP error message XW220 - Checksum is invalid for segment "&1" ?

  The SAP error message XW220, which states "Checksum is invalid for segment '&1'", typically occurs in the context of data transfer or data processing within SAP systems, particularly when dealing with IDocs (Intermediate Documents) or other data segments. This error indicates that the checksum calculated for a specific segment does not match the expected checksum, suggesting that there may be data corruption or inconsistency.
  Causes:
  
  Data Corruption: The data in the segment may have been altered or corrupted during transmission or processing.
  Inconsistent Data: The data being processed may not conform to the expected format or structure, leading to checksum mismatches.
  Configuration Issues: Incorrect configuration settings in the IDoc processing or data transfer settings can lead to checksum errors.
  Version Mismatch: If there are different versions of the data structure being used, it can lead to discrepancies in the checksum calculation.
  
  Solutions:
  
  Reprocess the IDoc: If the error is related to an IDoc, try to reprocess the IDoc. You can do this using transaction codes like WE19 (Test tool for IDocs) or WE02 (Display IDocs).
  Check Data Integrity: Verify the integrity of the data being processed. Ensure that the data is complete and correctly formatted.
  Review Configuration: Check the configuration settings related to IDoc processing or the specific data transfer process. Ensure that all settings are correct and consistent.
  Update or Correct Data: If you identify specific segments that are causing the issue, you may need to correct or update the data in those segments.
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error. SAP frequently updates its knowledge base with solutions for known issues.
  Debugging: If the issue persists, consider debugging the process to identify where the checksum calculation is failing. This may require technical expertise.
  
  Related Information:
  
  IDoc Structure: Understanding the structure of the IDoc and the segments involved can help in diagnosing the issue.
  Transaction Codes: Familiarize yourself with transaction codes like WE02, WE19, and WE20 for monitoring and testing IDocs.
  SAP Support: If the issue cannot be resolved internally, consider reaching out to SAP Support for assistance, providing them with detailed information about the error and the context in which it occurred.
  
  By following these steps, you should be able to identify the cause of the checksum error and implement a solution to resolve it.
