No hierarchy step could be determined for the object &

What causes this issue?

No value was entered in the "Level" field of the object &V1& in the
Viewcluster object structure. The value could not be determined during
generation, as an object which is not in the object structure is
specified as predecessor.

System Response

How to fix this error?

Enter a whole number between 1 and 10 as "Level".
This value specifies the hierarchy level of a Viewclusters object. A
header entry has level 1, an object which depends on a header has level
2, etc.
The level influences the layout of the subscreen. The short
descriptions are indented appropriately in the subscreen, and a
preceeding arrow indicates the dependency. It has no other
significance.
