SLA Rule for Depreciated vs Undepreciated Assets

Summary: We have a requirement to drive one of our Chart of Account segment value based on whether the asset started depreciating or not depreciated Our goal is to drive the segment value based on whether an asset has started depreciating or not before its retirement. Specifically, we need the segment value to be 30 for assets that have been depreciated (i.e., assets with a depreciation reserve) and 20 for assets that have not yet depreciated.

For example: ("Category Flexfield Segment 1"(FA,S,S) !=INTANGIBLE 'AND' "Depreciation Reserve Entered Amount" > 0)

However, this rule did not worked correctly because it seems that the depreciation amount becomes zero if an asset is fully retired.
