  Ensure that the lower limit ratio is indeed less than the upper limit ratio.
  
  
  
  Adjust the Ratios:
  
  If you find that the lower limit ratio is greater than or equal to the upper limit ratio, adjust the values accordingly.
  Save your changes.
  
  
  
  Test the Allocation:
  
  After making the adjustments, try to execute the allocation or distribution process again to see if the error persists.
  
  
  
  Related Information:
  
  Documentation: Refer to SAP documentation or help files for detailed information on allocation structures and the significance of limit ratios.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KSU5 (for cost center allocations) or KSV5 (for internal orders) to navigate the system effectively.
