How To Fix RSDMD218 - Unable to write record '&1' to &2 at second attempt

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDMD - Messages for master data

• Message number: 218

• Message text: Unable to write record '&1' to &2 at second attempt

What causes this issue?

During the master data update the master data tables are read to
determine which records of the passed data package have to be inserted,
updated, or modified. Between reading the tables at the start of package
processing and the actual insertion of records at the end of package
processing, some records are inserted into the master data table by a
simultaneously running request.
The master data update tries to overwrite the records inserted by the
simultaneously running process but this database record modification
returns an unexpected error.

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?

Check if the values of the master data record with the key mentioned in
this message are updated correctly.
Run master data RSRV test "Time Overlaps of Load-Requests" and specify
the request that is currently running to analyze what requests are
running simultaneously and may have affected the master data update
process.
Re-schedule your master data load process to avoid such situations in
future.
Read SAP note 668466 for more information about master data update
scheduling.

• What is the cause and solution for SAP error message RSDMD218 - Unable to write record '&1' to &2 at second attempt ?

  The SAP error message RSDMD218, which states "Unable to write record '&1' to &2 at second attempt," typically occurs in the context of data extraction or data loading processes in SAP BW (Business Warehouse). This error indicates that there was an issue when trying to write a record to a data target (like an InfoProvider) after a first attempt failed.
  Causes:
  
  Data Locking Issues: The data target might be locked by another process or user, preventing the current process from writing to it.
  Data Consistency Issues: There may be inconsistencies in the data being loaded, such as missing mandatory fields or data type mismatches.
  Database Constraints: The database might have constraints (like primary key or foreign key constraints) that are violated by the data being written.
  System Resource Issues: Insufficient system resources (like memory or disk space) can lead to failures in writing data.
  Transport Layer Issues: If the data is being transported between different systems, there may be issues with the transport layer.
  
  Solutions:
  
  Check Locks: Use transaction codes like SM12 to check for locks on the data target. If there are locks, you may need to wait for them to be released or contact the user who has locked the data.
  Validate Data: Ensure that the data being loaded is complete and adheres to the required formats and constraints. You can use transaction codes like RSA3 to test the data extraction.
  Review Database Constraints: Check the database for any constraints that might be causing the write operation to fail. Ensure that the data being written does not violate any constraints.
  Monitor System Resources: Check system resources using transaction codes like SM50 or ST02 to ensure that there are no resource bottlenecks.
  Check Logs: Review the application logs (transaction SLG1) for more detailed error messages that can provide additional context on the failure.
  Retry Mechanism: If the error is transient, implementing a retry mechanism in your data load process may help.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSA3 (Data Source Test), and SLG1 (Application Log).
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide patches or updates that could resolve the issue.
  Documentation: Review SAP documentation related to data loading and extraction processes for best practices and troubleshooting steps.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or BW team for further investigation.
