• What is the cause and solution for SAP error message EL401 - MR &3 of &4 is lower than the entered MR for device &1 register &2 ?

  The SAP error message EL401 indicates that there is a discrepancy between the measured reading (MR) entered for a specific device and register and the previously recorded measured reading. Specifically, the error states that the new measured reading is lower than the previously recorded one, which is not allowed in the context of meter readings.
  Cause:
  The error occurs when:
  
  A new measured reading (MR) is entered that is lower than the last recorded reading for the same device and register.
