• What is the cause and solution for SAP error message PSSC_NET039 - Deduction type &2, priority &3 must be either perc. or amnt, not both ?

  The SAP error message PSSC_NET039 indicates that there is a configuration issue with a deduction type in the SAP system. Specifically, it states that a deduction type (identified by &2) with a priority (identified by &3) must be defined as either a percentage (perc.) or an amount (amnt), but not both at the same time.
  Cause:
  This error typically arises when:
  
  A deduction type is incorrectly configured in the system to have both a percentage and an amount defined simultaneously.
  There may be a misunderstanding in the setup of deduction types in the relevant configuration settings.
