Understanding dimension processing options
We must ensure that each dimension referenced, by a particular measure group, has an up-to-date dataset prior to processing any partitions in that measure group. If we attempt to process a measure group before dimensions have up-to-date data, we will encounter missing key errors and the measure group / partition processing will fail.
How it works...
