[AIM: Conditions for actions] Making a condition depending on previous status?

Hi all.

The idea is to make an e-mail notofication for processor when the end user rejects proposed solution or provide some new information (when status "proposed solution"/"customer action" is changed to "in process"). Without making a new status.

I didn't find any expression like "Previous status" in condition formating of the action.

I tried to use this condition "&CRM Service Request.Changed By = &CRM Service Request.Created By" (so it means that if the last user who changed the incident was the reporter of the incident - the processor should be notified). But it doesn't work.

Any ideas?

Best regards,

Artem
