Deferred Expense Reconciliation Report - Sub ledger

I’m looking at Deferred Expense Reconciliation Report, I have quite a lot of variances due to sub-ledger has no movement.
Any ideas?

Do you have deferred expenses that haven’t started yet? I only ask that the Deferred Revenue Reconciliation report use to work perfectly in 10.0 but then in 10.2.100 it was off by the deferred amount that was in the future so it never balanced to the G/L again. I think the behavior was correct in the report that bucketed the amounts but that doesn’t give it by GL Account.

Just a thought.
