Diagnosis
Interactive planning creates a message log for some events, which occurwhen structuring the planning screens. The following messages are beinggathered at present:

• Messages from the verification of combinations of characteristic values


• Messages on invalid combinations of characteristic values in
characteristic hierarchies

• Messages on combinations of characteristic values, which are locked in
data slices for planning
Since the combinations of characteristic values are not normally takeninto account when structuring the sceen, a 'Detail' function is usuallyin the message, which displays the exact combination of affectedcharacteristic values.

Procedure
The messages displayed in the additional log are designed as anadditional source of information; however, interactive planning can becontinued when the additional log contains messages. The additional logis particularly useful in the Customizing phase.
