• What is the cause and solution for SAP error message WER_UI091 - Please select only one rule set at a time from the table ?

  SAP Error Message:
  
  WER_UI091 – "Please select only one rule set at a time from the table"
  
  Cause:
  This error occurs when a user tries to select multiple rule sets simultaneously in a context where only one rule set selection is allowed. Typically, this happens in SAP Workflow or Business Rule Framework plus (BRFplus) applications where the UI or processing logic expects a single rule set to be selected for further processing, but the user has selected more than one.
  
  Explanation:
  
  The system enforces a restriction that only one rule set can be processed or edited at a time.
  Selecting multiple rule sets violates this constraint, triggering the error.
  This is often encountered in transaction screens or custom UI components where rule sets are listed in a table or selection list.
  
  
  Solution:
  
  Select only one rule set from the table or list before proceeding.
  If multiple rule sets need to be processed, handle them one at a time or adjust the process logic to support multiple selections if applicable.
  Review the UI or program logic to ensure it restricts selection to a single entry (e.g., use radio buttons instead of checkboxes if only one selection is allowed).
  If this error occurs unexpectedly, check for any custom enhancements or modifications that might be allowing multiple selections.
  
  
  Related Information:
  
  Context: This message is commonly seen in BRFplus rule set maintenance or workflow rule selection screens.
  Transaction Codes: May appear in BRFplus (e.g., BRF+), workflow rule configuration, or custom applications using rule sets.
  SAP Notes: Check SAP Notes related to BRFplus or workflow rule set selection for any known issues or patches.
  Debugging: If unsure why multiple selections are allowed, debug the UI component or the selection logic to verify the control behavior.
