• Message class: EL - IS-U meter reading data processing

• Message number: 155

• Message text: Device &1 MR date &2: Maximum demand limit exceeded by &3 &4

What causes this issue?

Validations have determined that consumption has exceeded the contract
demand limit. The limit is stored in an operand that is defined in
table TE409. This table contains all validation parameters allocated to
the device via the validation class (in the rate).
The operand value is entred in the rate category or the installation
facts.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message EL155 - Device &1 MR date &2: Maximum demand limit exceeded by &3 &4 ?

  The SAP error message EL155 indicates that the maximum demand limit for a specific device has been exceeded. This message is typically related to energy management and monitoring in SAP, particularly in the context of utilities and energy consumption.
  Cause:
  The error message EL155 is triggered when the actual demand (measured in kilowatts or another unit) for a device exceeds the predefined maximum demand limit set for that device. This can occur due to various reasons, such as:
  
  Increased Load: A sudden increase in the load on the device, possibly due to operational changes or equipment malfunction.
  Incorrect Configuration: The maximum demand limit may be set too low for the actual operational requirements of the device.
  Data Entry Errors: Incorrect data entry in the system regarding the device's specifications or limits.
  Seasonal Variations: Changes in demand due to seasonal factors or operational cycles.
  
  Solution:
  To resolve the EL155 error, you can take the following steps:
  
  
  Review Device Configuration: Check the configuration settings for the device in question. Ensure that the maximum demand limit is set appropriately based on the expected operational load.
  
  
  Analyze Demand Patterns: Look at the historical demand data for the device to understand if the current demand is an anomaly or a new normal. This can help in deciding whether to adjust the maximum limit.
  
  
  Adjust Maximum Demand Limit: If the current maximum demand limit is too low, consider increasing it to accommodate the actual demand levels. This can be done through the relevant configuration settings in SAP.
  
  
  Investigate Load Changes: If there has been a recent change in operations or equipment that could have caused the increased load, investigate and address those changes.
  
  
  Monitor for Recurrences: After making adjustments, continue to monitor the device to ensure that the demand does not exceed the new limits and that the changes have resolved the issue.
  
  
  Related Information:
  
  Transaction Codes: You may need to use specific transaction codes in SAP to access device configuration and demand settings, such as transaction codes for energy management or device management.
  Documentation: Refer to SAP documentation or help files related to energy management and device configuration for detailed instructions on managing maximum demand limits.
  Support: If the issue persists or if you are unsure about making changes, consider reaching out to your SAP support team or consulting with an SAP expert.
  
  By following these steps, you should be able to address the EL155 error and ensure that your device operates within the defined limits.
