Feature PLOGI could not be reported on.

What causes this issue?

The feature PLOGI determines whether integration between Personnel
Administration and Organizational Management is active for an employee.
The feature could not be evaluated. It could not, therefore, be
determined whether integration is active for this employee or not.
There could be various reasons for this:
The feature's decision tree is structured in such a way that the
current specifications for the decision operation lead to an ERROR.
Each decision possibility within a characteristic can be assigned to a
certain operation. In addition, a decision possibility ** can also be
defined, which will be assigned to all unexecuted decision
possibilities (a default value). If this default is missing, some
decision possibilities could be missing as well.
The feature has to be generated before you use it.
For feature PLOGI, there is an invalid ID in T549D.
The program (or report) calls up the feature using a function which
expects a field return as a return. The feature is defined so that it
produces a table return.
