GL revaluation correction and AP trial balance

Hi All ,

We are 1.5.10 . One of the GL created a journal to correct the Revaluation journal for a old dormant balancing . The account involved is the AP liability account and this correction journal is causing an imbalance between the GL and AP trial balance . It is also noticed that there is no outstanding balance on the supplier account and balance is resultant of the revaluations happening over a period of 1.5 years . How can we bring the GL and AP in synch and also prevent the revaluation of the dormant balance .

Please let me know.

Thanks in advance
