Update Register Group of a device with Rate Type and Fact Group (Single FM)

Hi Experts,

I have a requirement to update the Register Group of an installed device. The new Register Group has more number of registers than the earlier one.

So, while updating the Register Group (EG41), I have to update the Rate Type and Fact Group of the Registers in the new Register Group.

To update the Register Group I have the FM ISU_S_DEVICEMOD_CHANGE but this FM does not have Rate Type or Fact Group fields in the parameters.

I tried debugging EG41 transaction and found an FM ISU_O_DEVICEMOD_ACTION that creates new Logical Register Numbers at runtime for the new created Register as per the new Register Group. The logic that this FM is using is quite complicated and I am not sure whether using the same logic is safe or not.

I digged so many threads but didnt find the way to update Register Group along with Rate Type and Fact group through a single FM.

Please help, Moderator note - comment removed due to violation

Thanks,

Manoj
