Draft comparison of the selected node is not possible

What causes this issue?

The selected node does not have a relevant data set. For example, if you
have created a draft by only selecting the <LS>Activity Processing</>
data set, the system displays this error when you select a work
breakdown structure element (WBSE) during draft comparison. This is
because activity processing data is not relevant to WBS elements.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
