Actual it is not possible to get the "last modified" timestamp of a document in the ARIS Document store. We want to get this timestamp for use in reports to search for outdated documents.
A (more worse) alternative is the abillity to sort documents by this timestamp in the ARIS Document Administration. But this needs manual handling for the outdated documents. So it's not the preferred solution.
Dear Mr Renner,
it is already today possible to sort documents manually by timestamp (see screenshot attached).
