Not really. It’s an app design consideration and understanding. What you really need is for the same process to be triggered by both apps.
Apps are primarily meant to be mutually exclusive when it comes to functionality. Otherwise, they become “tied” together and are not really two separate apps. I.e. you always have to have one with the other.
So there two options for you:
Combine the two apps into one so they can share functionality. Instead, have two sets of views - Help Desk views vs Main app views - controlled by user roles or similar permission based settings. This would be advisable if there are many processes that need to be shared.
Implement the same automation from the Main app into your Help Desk app to apply the same updates.
Personally, for your use case I would prefer Option 2. It keeps the Help Desk app simple and easy to give to users.
Ideally, AppSheet would provide a Common area where we can place processes that don’t really belong to any certain app but can be used by ANY app. Think of it as developer defined functions that compliment the system functions like SELECT(), FILTER(), DATE(), RANDBETWEEN(), etc. This is very different than triggering a process in another app.
Unfortunately, we do not have that so we must duplicate the processes when needed.
