How to stop asset depreciation

Hello,

We are on PSOFT 9.2. We have few assets which have been put on Suspended Status but they are still depreciating which is causing negative depreciation to be generated. On the other hand, there are some assets with Suspend Status that have stopped depreciating. What factors are responsible for depreciation process to be stopped. We have 1 BU and 1 Book- CORP.
