Hey @karstenkoehler , once again, this is bringing a nice solution! What I’m going to do :
- Create a boolean property at deal level : Purchased between the last 12 and 6 months
- Create a boolean property at deal level : Purchased in the last 6 months
- Setup a daily workflow that will verify time range deal has been created
- Create custom calculation property (for me, at contact level) for each Time range I want to calculate the count.
- Create the final custom calculation property (comparing previous 2 calculation property) that will determine if deal count is decresing over time for a contact.
Solution is complete for me, thanks a lot.
