Learning advanced dimension processing options

In the previous recipe, you processed a few dimensions after altering the degree of parallelism. You can specify additional options to handle any errors you might encounter during processing from the same dialog using the Dimension key errors tab. You should handle a majority of the data quality issues in the Extraction, Transformation, and Loading (ETL) layer of your application. However, in some cases it's acceptable to ignore processing errors, particularly during the development stage when your ETL routines might be half-baked. The following table lists the remaining dimension processing options you can specify:

Processing option	Description
Key error action	The default action in case of an error is to convert the attribute key to the unknown member. The other alternative is to discard the record. Though this is a viable alternative during the development phase, you should be careful with discarding dimension records in production since...
