Adding extra fields in EL31 output

Hi,

We have requirement wherein we need to add extra fields in the Meter Read Results output in transaction EL31. These new fields will be fetched from join on table EABL, ETDZ and EMRDETAIL.

Is there any BADI or EXIT available for this? I tried few EXITs but couldn't modify the output ALV.

Thanks,
