• What is the cause and solution for SAP error message AJ521 - Operand &1 only permissible for interval meter rates ?

  The SAP error message AJ521 indicates that there is an issue with the operand being used in the context of interval meter rates. This error typically arises when a calculation or operation is attempted on a non-interval meter rate, which is not permissible.
  Cause:
  The error message AJ521 is triggered when:
  
  An operand (like a rate or value) is being applied to a meter that is not configured as an interval meter.
