Something like that.  Basically in the Publisher channel, Pub-command, likely, you catch a modify and read teh data and send toa  PRD.   The problem is, doing this in a general, works for all data, fashion is hard.

Any solution you come up with will likely be very site specific.  Which is fine, but as I say a general solution is hard.

I'm wondering, Identity Application should be mobile friendly now. Do we still need the approvals app since direct accessing the portal through mobile will work the same. 

I found the answer to my question, I have to use the expression: ${entity.RequestCausesRequest[Active=true].count==0}
