• What is the cause and solution for SAP error message W_DSD_01036 - &1 records have been modified ?

  SAP Error Message:
  
  W_DSD_01036 &1 records have been modified
  
  Meaning / Cause:
  This warning message typically appears in SAP when you are trying to update or process data records (for example, in Data Services, Data Migration, or other data-related transactions), and the system detects that the records you are working on have already been modified by another user or process since you last read them.
  In other words, the data you are trying to update is no longer in the state you expect because it has been changed by someone else. This is a concurrency issue, often related to optimistic locking mechanisms in SAP to prevent overwriting changes made by others.
  
  When does it occur?
  
  During data upload or batch processing.
  When multiple users/processes try to update the same records simultaneously.
  In Data Services or Data Migration tools when the source data has changed after it was initially read.
  In transactions or programs that use update locks or check for data consistency before updating.
  
  
  Solution / How to handle it:
  
  
  Refresh Data:
  
  Before updating, refresh or re-read the data to get the latest version. This ensures you are working on the most current data.
  
  
  Check for Concurrent Updates:
  
  Identify if other users or processes are updating the same records. Coordinate to avoid simultaneous updates.
  
  
  Implement Proper Locking:
  
  If possible, use locking mechanisms to prevent concurrent modifications during critical update operations.
  
  
  Retry Logic:
  
  Implement retry logic in custom programs or batch jobs to handle this warning gracefully by re-reading and re-processing the data.
  
  
  Analyze the Process Flow:
  
  Review the process or program logic to ensure that data is not being held too long before update, which increases the chance of concurrent modifications.
  
  
  Check Custom Code / Enhancements:
  
  If this occurs in custom developments, verify that the code properly handles data consistency and locking.
  
  
  
  Related Information:
  
  This message is a warning (W_), not an error, so the system is alerting you to a potential data consistency issue.
  It is related to data concurrency and optimistic locking.
  Similar messages can appear in various SAP modules dealing with data updates, such as MM, SD, FI, or custom applications.
  In SAP Data Services or Data Migration Cockpit, this message can indicate that the source data changed after extraction or during processing.
