SAP Error Message - Details

• Message type: E = Error

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

• Message number: 487

• Message text: Device &1, reg. &2, MR date &3: Interpolation of MR result not possible

What causes this issue?

You cannot derive the meter reading result for &3 of device &1 and
register &2. This is because a real meter reading result exists in the
period between the control meter reading result and the meter reading
result to be derived.

• What is the cause and solution for SAP error message EL487 - Device &1, reg. &2, MR date &3: Interpolation of MR result not possible ?

  The SAP error message EL487 typically occurs in the context of the SAP system's handling of measurement documents, particularly when dealing with measurement readings and their interpolation. This error indicates that the system is unable to interpolate the measurement result for a specific device and registration date.
  Cause:
  The error can arise due to several reasons, including:
  
  Missing Measurement Documents: There may not be enough measurement documents available for the specified device and registration date to perform interpolation.
  Incorrect Measurement Data: The measurement data might be incorrect or incomplete, leading to issues in calculating the expected values.
  Configuration Issues: There could be configuration problems in the device or measurement point settings that prevent proper data processing.
  Time Gaps: If there are significant time gaps between measurement readings, the system may not be able to interpolate effectively.
  
  Solution:
  To resolve the EL487 error, consider the following steps:
  
  Check Measurement Documents: Verify that there are sufficient measurement documents for the device and registration date in question. Ensure that the data is complete and accurate.
  Review Measurement Data: Look for any discrepancies or missing values in the measurement data. Correct any errors found.
  Configuration Review: Check the configuration settings for the device and measurement points. Ensure that they are set up correctly to allow for interpolation.
  Adjust Time Intervals: If there are large gaps between measurements, consider adjusting the measurement intervals or adding additional readings to facilitate interpolation.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to measurement documents and interpolation settings.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as EL31 (Display Measurement Document) or EL21 (Display Measurement Point) to help diagnose the issue.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or a technical consultant who specializes in SAP IS-U (Industry Solution for Utilities) or the relevant module you are working with.
