Unable to match Assessment entries in Ke24 with FI

Hi Experts,

I am unable to match data in report KE30 with data in FI. For instance, for one admin cost, i extract the gl balance from fbl3n and try to match it with ke30/ke24 - but one to one match is not possible.. as there is no common field nor able to match single amount in fbl3n in ke 24.

Please suggest some ways to reconcile between fbl3n and ke30

Regards

Malathi
