Hi @furgun , Does your solution has Business Process Flow? If yes, then you must be aware that when you create BPF at that time to store the information about the different stages involved in BPF , Microsoft creates a table in background for you. So, you must have added the actual BPF (process) in your solution, however you also need to add the associated table which is created by Microsoft.
Example: I have 2 BPF in my solution as shown in below screenshot:

Then I have to make sure that I have also added its associated table as shown in below screenshot.

Now, in order to add these tables, you need to click on Add existing component in your solution.

Then search for the table name. So, you can try searching with the same name as your BPF name is.

Once added then publish the customization and then export the solution and then import to target environment. This should work for you.
