Diagnosis
A consolidation frequency needs to be assigned (either explicitly orimplicitly) to each task used in the monitor. This is because thedisplay of tasks in the current period is dependent on the consolidationfrequency of that task.
This condition has not been met for task &V1& for one of the followingreasons:
RESET N1
A valid consolidation frequency has not been assigned to the currentcombination of versions.
An invalid consolidation frequency has been explicitly assigned to taskV1.
Also note that the display of "balance carryforward" tasks in themonitor is dependent on the consolidation frequency assigned to thecurrent version combination.

Procedure
Make sure that a valid consolidation frequency is assigned to thecurrent combination of versions. If this is not the case, supply themissing assignment.
Check the frequency assignment in the customizing settings for task &V1&
