No active ABAP Dictionary (DDIC) type '&1' found

What causes this issue?

The system has checked the current data object and determined that the
ABAP Dictionary object '&v1&' to which the data object is bound could
not be found.
When working with Decision Service Management, it is a typical error
cause that the binding for the data object has been established before
the current application has been assigned to a managed system.
Therefore, the bound ABAP Dictionary object may exist in the current
design time system, but not in the managed system.

System Response

The object cannot be activated.

How to fix this error?

Check whether the error situation described above applies. If so, make
sure the respective ABAP Dictionary object is available in the managed
system.
