Asset Disposal Error

We've noticed an error with our asset disposals since upgrading to 64 bit.

When running the mass asset disposal job (R5612104), this updates the asset record with a disposal code and disposal date, as it always has. It also generates a batch that must first be posted on the G/L side, followed by the F/A side.

This batch posts to the G/L side no problem, but fails on the F/A post (R12800).

The cost account and accumulated depreciation amounts post to the asset as intended, but the write off amount does not post to the asset. It says it can't post to an asset that's been disposed.
