% In this table record we hold the state (work item) of a transaction that is currently processed (worked on). A work
% item is created when a requiest from the IPAd positively maps to a pending order in the REST table
% (see mnesia_db_rest). A work item can be understood as the dynamic state of the ongoing connection between eIM and
% IPAd (and SM-DP+). When the transaction is done and the work is finished, the related work item is deleted and the
% outcome is recorded at the related REST resource.
