  The SAP error message SWF_RLS_001162 indicates that there is an issue with a condition in a workflow or a rule where the left operand of a specified operator (in this case, &1) is expected to be a number, but it is not. This typically occurs in the context of workflow rules or decision points where numeric comparisons are made.
  Cause:
  
  Data Type Mismatch: The left operand is not of a numeric type. It could be a string or another data type that cannot be interpreted as a number.

  Solution:
  
  Check Data Types: Ensure that the left operand is indeed a numeric type. You can do this by checking the data type of the variable or field being used in the condition.
  Validate Input Values: Make sure that the values being passed to the workflow or rule are valid and not null or empty. You may need to add validation checks before the condition is evaluated.
  Debugging: Use debugging tools to trace the values of the operands at runtime. This can help identify where the incorrect value is coming from.
  Modify the Condition: If the left operand can sometimes be non-numeric, consider modifying the condition to handle such cases, possibly by using type conversion functions or additional checks.
  Review Workflow Logic: Review the logic of the workflow to ensure that all paths leading to the condition are correctly assigning numeric values.
