  Message Numbers: 390 to 399
  Context: These messages typically indicate problems with Rule Sets — collections of rules used to determine workflow behavior, conditions, or decisions.
  
  
  Common Causes
  
  
  Missing or Incorrect Rule Set Definition:
  
  The specified Rule Set does not exist or is not properly defined in the system.
  
  
  
  Syntax Errors in Rule Set:
  
  The Rule Set contains syntax errors or invalid expressions that prevent it from being processed.
  
  
  
  Authorization Issues:

  Transport or System Inconsistencies:
  
  Rule Sets transported between systems may be incomplete or inconsistent.
  
  
  
  Incorrect Rule Set Assignment:
  
  The workflow or application component references a Rule Set that is not assigned or incorrectly assigned.
  
  
  
  
  Typical Solutions
  
  
  Check Rule Set Existence and Definition:
  
  Use transaction SWO1 or SWI1 to verify the Rule Set exists.
  Use SWI2_FREQ or SWI6 to analyze workflow rules.
  Check the Rule Set in the Rule Builder (transaction SWI1 or SWI2_RULES).
  
  
  
  Validate Rule Set Syntax:
