SAP SM 7.2. Transaction asignment in Project management

Hello!

I configure standard functionality of SAP SM 7.2. SP2.

SAP Learning Hub has course SAP Solution Manager 7.2, SP01: Learning Map for Project Management.

SAP Project has the button "Create with transaction Assignment"

My demo project hasn't this button.

What settings I have to make in the project that the button has appeared?

Thanks for answer.
