Problem statement: It is quite frequent in workflow in Dynamics AX that one would like to notify users when certain approvals have occurred, tasks have been completed or when errors occur. This is pretty easy to accomplish out of the box with Dynamics AX by using the notifications on approvals, tasks or on the workflow as a whole. However the options are pretty limited and not very dynamic (especially in AX 2009) and up until AX2012 you have only really been allowed to assign to specific users (i.e. by user id). This means that it is very difficult to accomplish complex notifications such as notify the following people when a document has been approved: Document Creator, Project Manager for the document’s project and all users assigned to the “Accountants” security role in AX.
This means that you can create a Custom “notification” participant provider for your system that can resolve any number of personalised lists of users as above.
For example we created a particpant provider with a couple these lists. In our custom participant provider we returned a unique token per list e.g. “Originator, Project Manager, Requester and CEO” and “Originator, Project Manager, Financial Manager and CEO”.
In the resolve method of the participant provider we then retrieved the workflow document out of the workflow context object and returned the “Created by” user, looked up the project on the document and returned the associated Project manager and finally looked up the Financial Manager and CEO from a custom parameters table in AX and returned them as well.
The actual creation of a custom participant provider is beyond the scope of this article but you can find some more resources over here:
I hope this sparks some thought and is useful to some:
