How to: Enable or Disable Writeback for a Partition
You configure writeback for a partition using the Partitions view in Cube Designer, which is accessed from Business Intelligence Development Studio.
Before you can enable writeback, the partition must be in a processed state. In addition, only partitions whose measures use the Sum aggregate function can be write-enabled. For more information about partition processing, see Partitions (Analysis Services).
For more information about writeback, see .Setting Partition Writeback.
Open the cube that contains the partition that you want to write-enable.
In the Cube menu, point to View, and then click Partitions.
Expand the group containing the partition that you want to write-enable, right-click the partition, and then click Writeback settings.
In Write enable - <Partition Name>, either type a name for the writeback table and specify a data source, or accept the defaults.
Click OK. The new writeback table will appear in the list of partitions under the original partition.
When you disable writeback for a partition, the writeback data becomes inaccessible and the measure group on which the partition is based becomes read-only.
