AJ521 - Details

• 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.
  The system expects an interval meter rate but receives a different type of rate or operand.
  There may be a configuration issue in the master data of the meter or the rate type being used.
  
  
  Solution:
  To resolve the AJ521 error, you can take the following steps:
  
  
  Check Meter Configuration:
  
  Verify that the meter in question is indeed set up as an interval meter. You can do this by checking the master data for the meter.
  Ensure that the correct rate type is assigned to the meter.
