I have also encountered this issue on a number of occasions, running v2015.1. Again, & annoyingly, it appears to occur after processing batches of disposals making it easy to miss at the time (particularly if you hold a significant no. of asset records in SAGE). Out of curiosity are you running a newer version? 

Interested party.

Hi Giles,

We are running the same version v2015.1. Maybe the version has a glitch? We have disposed of assets before and never encounter this problem.

Hello VWP,

To fix the prior through date, follow the steps in Depreciation this run is too high which will correct the Depreciation this run (DTR).

A Disposal is a Calculation of Depreciation. Once the disposal information is entered, the Current through date of the asset is the end of the month of the disposal so that in running depreciation, if the Force Recalculate box is Checked, then the lost of the Prior through date is to be expected, since that is exactly what the Force Recalculate is supposed to do.

But it is rare that is the case. Other than the Force Recalculate, I seen it happen a lot where a single disposal or a bulk disposal causes the prior through date to get lost, but I have never been able to reproduce the issue in anything like a consistent manner. There have been times in the past where certain combination of actions would cause this more often that others, but not every single time and almost never on any of my local systems.

My advice to avoid the whole question of whether the prior through date is correct or not, before you run depreciation to the current month, first run it for the prior month - Don't even generate a report because that could only be confusing and is not needed. 

That has the effect of setting the prior through date on all assets to be the prior month and the varying DTR is not an issue. 

Hi Delray,

We did that. We forced the asset that had the wrong thru date to recalculate to the prior month and then recalculated the current month depreciation. The asset is still showing the incorrect through date on the depreciation expense report and as a result is showing the incorrect monthly depreciation expense. This is a fully depreciated asset and in addition the asset shows the correct prior thru date on the asset detail list. I am not sure how to fix this.

Thanks.

run depreciation on this asset back to the prior FY end, then bring it forward.
