Asset Depreciation in Epicor 9.05

Hi,
Does anyone use the Asset Management module in Epicor 9.05 ?

We have converted from Vantage 6.1 to Epicor 9.05 vs607. Our asset data has converted correctly as have asset transactions that occurred in Vantage. However I cannot get depreciation calculations to post to the ledger. The "errored" post goes to the Review Journal but on checking that I cannot see any error messages even the Review Journal report (270 pages long) shows me nothing.

I am suspecting that we may not have done a particular required setup in Epicor but I cannot find what. I have set up a Clearing Account in GL Control Code and also Provision Control Accounts for all our Asset Groups in GL Control Code. Depreciation calcs still won't post.

Any help would be greatly appreciated.

Jill
