• What is the cause and solution for SAP error message /PLMU/UI_VWR001 - Incorrect values defined in the BAdI; default viewer will be used ?

  The SAP error message /PLMU/UI_VWR001 Incorrect values defined in the BAdI; default viewer will be used typically indicates that there is an issue with the configuration of a Business Add-In (BAdI) related to the UI (User Interface) viewer in SAP. This error occurs when the values defined in the BAdI implementation do not meet the expected criteria or are not valid, leading the system to revert to a default viewer instead.
  Cause:
  
  Incorrect Configuration: The BAdI implementation may have incorrect or incomplete settings. This could be due to missing parameters, invalid values, or misconfigured logic in the implementation.
  Version Mismatch: There may be a mismatch between the version of the BAdI and the version of the application or component that is trying to use it.
  Transport Issues: If the BAdI implementation was transported from one system to another, there may have been issues during the transport process that led to incorrect settings.
  Authorization Issues: The user may not have the necessary authorizations to access the BAdI implementation correctly.
  
  Solution:
  
  
  Check BAdI Implementation: 
  
  Go to transaction SE19 (BAdI Implementation) and check the implementation for the BAdI related to the UI viewer. Ensure that all required parameters are correctly set and that the logic is valid.
  If necessary, compare the implementation with the standard implementation to identify discrepancies.
  
  
  
  Review Configuration: 
  
  Check the configuration settings related to the BAdI in transaction SPRO. Ensure that all necessary settings are in place and correctly configured.
  
  
  
  Debugging: 
  
  If you have access to debugging tools, you can set breakpoints in the BAdI implementation to see where the values are being set incorrectly or where the logic fails.
  
  
  
  Check Authorizations: 
  
  Ensure that the user has the necessary authorizations to execute the BAdI. You can check this in transaction SU53 after the error occurs.
  
  
  
  Transport Check: 
  
  If the BAdI was recently transported, check the transport logs for any errors or warnings that might indicate issues during the transport process.
  
  
  
  Fallback to Default Viewer: 
  
  If the issue cannot be resolved immediately, the system will continue to use the default viewer. This may be acceptable temporarily while you work on fixing the BAdI implementation.
