System Response

The statistical WBS element &V1& is excluded from from further
processing when you execute this cycle. This is because you have a
statistical posting to a statistical WBS element, but there is no true
account assignment to the cost center.

maintenance, the system first accepts statistical WBS element &V1&, so
that you can maintain the tracing factor values without leaving the
cycle. After this, however, you should enter the cost center to which
you want to post so that this receiver is valid.
The system issues a warning during the formal check in cycle
maintenance to remind you to enter a cost center.

How to fix this error?

In the master record of the WBS element you should enter a cost center
to which you want to post to. this ensures that the WBS element is
accepted by the system as a valid receiver.
