Problem with meter reading history after change on logical register number(EG60)

[former_member590332]

Hi Experts,

I have a requirement were i must keep the history of meter readings from a former device that has been removed(Transaction: EG32) to be considered for estimation and validations, after a new device is installed(Transaction: EG31).

After I perform the installation with EG31, the device receive a new logical register number and does not consider the meter readings of the removed device for estimation and validations, as shown below:

Meter reading history not considered for validations:

I change the logical device number back to the last device number that has been removed by using the EG60 transaction, in hopes that by doing that, the meter reading history of the former device would be retrieved, as shown below.

Change from “2” to “1” on EG60:

As it seems, the logical number of the device installed changes correctly to the old device number:

After the change, I try to estimate the next periodic meter reading result using EL28, but I get the errors below and the meter reading historic of the former device is still not considered for validation and estimation:

Message no. EL185: Device E13I0003140D register 001: estimation could not determine a valid MR

Message no. EL262: Error reading internal table during extrapolation

Meter reading historic is not considered for validations:

Does anyone know what could be wrong with the logical number change that I made, or any ideas on how to keep the history of meter readings after a removal(EG32) and installation(EG31) of device?
