Hello Ash,
For the fixed asset summary list, do you mean the Fixed asserts -> Fixed asserts list page in Fixed asserts Module?

Its form name is AssetTable, whose datasources are AssetTable and LogisticsPostalAddress. Both table don't contain a field "Status".

So please let us know which table is the "status" field from. Then you can extend the AssetTable form and add a new datasouce containing the "status" field.
