Missing data while importing journals from feeder system

Hi,

We are facing one issue while Month end closing of General Ledger Module.

We have one feeder system which will post directly to the General Ledger via GL_INTERFACE table and one staging table. This month, in the staging table we found 6402 records with the total of -2,349,456.51 GBP. But in the system , two journals has been posted against this source with the total of -834,921.47 GBP .

We are getting the difference of -1,514,535.04 GBP. I checked with GL_INTERFACE table, there is no records error out. Unfortunately, we are importing journal as summary not in detail mode. So, we don't know how to check the difference.
