Sort Vote Time in Descending Order for Signoffs in Aras Innovator

By default, signoffs are sorted by vote time in ascending order. That means the latest record will be at the bottom. It is hard to check the newest information if there is a lot of records, and the "Vote Now" link will also be at the bottom
Signoff page is rendered by running a Report named "Workflow Process History". And a Report Item can define style sheet for output.
Therefore, open the style sheet of Workflow Process History and find sort definition at line 189 (shown in Figure 1), there are 2 conditions:
  • Sort "state" in descending order.
    For a valid Workflow Process, there are only 2 kinds of Life Cycle State for Activity -- Active/Closed. So, according to alphabetical order, "Closed" will be sorted before "Active".
  • Sort "closed_on" in ascending order.
    In order to sort by vote time, date string should be split into numbers. Using XSLT function -- substring -- can extract all these numbers. And then, they could be sorted in numerical order.

Figure 1

After knowing the principle, it is easy to change the sorting rule. Just reverse the original setting, change "sort" to ascending order and "closed_on" to descending order (like Figure 2).

Trigger Sequence of Promotion Events in Aras Innovator

There are several Server Event could trigger Method during item promotion: ItemType: OnBeforePromote, OnAfterPromote; Life Cycle: Transition Pre, Transition Post. Trigger sequence of above events is shown in below figure: It's important to note that "Transition Post" cannot rollback while exception throws because item promotion is finished after "OnAfterPromote" That means even if throwing exception, the life cycle will still stay at promoted state. Please note, all above events will not be triggered when "OnPromote" event exists (due to this will overwrite original system process).
