Hi Deeppak;
I have same issue and while searching on forums and another related sites I found something is mentioned related to such issue suggests you may need to correct values on Acc. Dep. G/L balances if the G/L is less than the AA balances through direct post on the Acc. Dep. reconciliation balances through OAMK and change the status for the account to be NOT RECONCILIATION ten post then return it.
Another reason could be is related to rounding if the differences are pretty small so you may need to check OAYO.
If that was helpful or giving you a glim for answer please do not forge helpful answer marks.
Best regards;
