• What is the cause and solution for SAP error message W/164 - Only enter amount as percentage (not both) ?

  SAP Error Message:
  
  W/164 Only enter amount as percentage (not both)
  
  Cause:
  This warning message appears when you enter both an absolute amount and a percentage value in a field or screen where only one type of input is allowed. Typically, in SAP pricing, discounts, surcharges, or condition records, you must specify either a fixed amount or a percentage, but not both simultaneously.
  For example, in condition records or pricing procedures, if you try to enter a discount as both a fixed amount and a percentage, SAP will raise this warning to prevent ambiguity in calculation.
  
  Solution:
  
  
  Enter only one type of value:
  
  Decide whether you want to specify the value as a fixed amount or as a percentage. Clear the other field so that only one is filled.
  
  
  Check the input screen or condition record:
  
  Look at the fields for amount and percentage. Remove the value from one of them.
  
  
  Review pricing procedure or condition type settings:
  
  If this happens frequently, verify if the condition type or pricing procedure allows both amount and percentage or only one. Adjust accordingly.

  Summary:
  
  Cause: Both amount and percentage entered where only one is allowed.  
  Solution: Enter either amount or percentage, not both.  
  Check: Condition records, pricing procedures, and input screens.
