Group value incorrect in GR55 and FAgll03

Hi Team

This is regarding issue notice in GR55 and FAGLL03 report. we have selected a few heads of accounts for validation.

when we compare between local currency to group currency --- the conversion ratio is very high and leads to an incorrect value. we have taken the dump of these accounts and try to map for each line item wise -- our observation the conversion is correct around + 14.32 Approx for all of them. however, when we try to do conversion for the same at the total column for these accounts the currency conversion is around 30 %. reason for this, these values are updating incorrectly in group amount.

now I would like to check if any of you have faced the similar issue and advise any resolution.

thanks
