Thanks very much @adeelfaisal !
This would work for an individual managing their Contacts/Deals however I am looking to develop a Management report that could identify slippages.
This report would be used as part of 1:1 with Sales team members.
It would be great to know if you still think it could work. Given you can choose IS and IS NOT for a contact owner filter, I would have thought it wouldn’t be too hard to add an IS NOT for a date field like Last Activity Date.
Thanks again! AC
