  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message: WER_UI105
  Message Text:
  
  Please use a unique rank for the new rule you wish to add to the rule set.
  
  Cause:
  This error occurs when you try to add a new rule to a rule set in SAP (typically in the context of BRF+ - Business Rule Framework plus), but the rank (or priority) assigned to the new rule is not unique. Each rule within a rule set must have a distinct rank to determine the order in which rules are evaluated or executed.
  If you attempt to add a rule with a rank number that already exists in the rule set, the system throws this error to prevent ambiguity in rule processing.
  
  Solution:
  
  Assign a unique rank number:
  
  When adding a new rule, ensure that the rank you assign is not already used by another rule in the same rule set.  
  Check existing ranks:
  
  Review the existing rules and their ranks in the rule set to find an available rank number.  
  Adjust ranks if necessary:
  
  If you want to insert a rule between two existing ranks, you may need to renumber the ranks of existing rules to maintain uniqueness and the desired order.  
  Use the BRF+ UI features:
  
  The BRF+ workbench often provides functionality to automatically assign ranks or reorder rules, which can help avoid manual errors.
  
  
  Related Information:
  
  BRF+ Rule Sets:
  
  In BRF+, rules within a rule set are evaluated in the order of their rank. The rank is an integer value that defines the priority or sequence.  
  Rule Evaluation:
  
  The rank determines which rule is evaluated first. Lower rank numbers typically mean higher priority.  
  Error Context:
  
  This error is common when manually creating or copying rules without adjusting the rank properly.  
  SAP Notes and Documentation:
  
  For more detailed guidance, refer to SAP Help Portal documentation on BRF+ or search for SAP Notes related to message WER_UI105.
