Diagnosis
An error occurred during activation of table &V1&.

System Response
In general, clustering improves the performance of read access to atable. Two types of clustering are supported: you can select indexclusters in InfoCube maintenance under Extras -> DBPerformance -> Clustering .
The current clustering of the database table is MultidimensionalClustering and the number/selection of MDC columns is not correct.

Procedure
Activate the InfoCube again and check whether errors occurred during
activation.
If the InfoCube already contains data and you want to change theclustering, you have to use reclustering. You can find this function in
InfoCube maintenance under More Functions -> Reclustering or inthe Data Warehousing Workbench in the function area Administration
-> Reclustering.
