• What is the cause and solution for SAP error message UMG265 - Collision Resolution is empty ! Resetting to old value. ?

  The SAP error message "UMG265 Collision Resolution is empty! Resetting to old value." typically occurs in the context of SAP's User Management Engine (UME) when there is a conflict or collision in user data during a synchronization or update process. This message indicates that the system encountered a situation where it expected a resolution for a collision (e.g., when two different sources provide conflicting information about a user), but no resolution was provided, so it defaults to the old value.
  Cause:
  
  Data Conflict: There may be conflicting user data coming from different sources (e.g., LDAP, database, etc.) that the UME is trying to synchronize.
  Configuration Issues: The collision resolution settings in the UME configuration may not be properly set, leading to the absence of a defined resolution strategy.
  Missing Parameters: Required parameters for collision resolution might be missing or incorrectly configured in the UME settings.
  
  Solution:
  
  
  Check UME Configuration:
  
  Go to the UME configuration settings in the SAP NetWeaver Administrator or the relevant configuration tool.
  Ensure that the collision resolution settings are properly defined. You may need to specify how to handle conflicts (e.g., prioritize one source over another).
  
  
  
  Review User Data Sources:
  
  Investigate the sources of user data to identify any discrepancies or conflicts. This may involve checking LDAP entries, database records, or other user repositories.
  Ensure that the data being synchronized is consistent and that there are no conflicting entries.
  
  
  
  Define Collision Resolution Strategy:
  
  If your system allows it, define a clear strategy for how to handle collisions. This could involve setting priorities for data sources or defining rules for merging conflicting data.
  
  
  
  Log Analysis:
  
  Check the logs for more detailed error messages or warnings that could provide additional context about the collision and help identify the root cause.
  
  
  
  Testing:
  
  After making changes, test the synchronization process to ensure that the error does not reoccur and that user data is being handled correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support resources for specific guidance on configuring UME and handling collision resolution.
