In Developer Studio, you set the type of dimension value handling, on a per mapping basis, by selecting a mode from the Match mode list in the Dimension Mapping editor, as illustrated below:

There are three match modes you can choose from:
- Normal
- Must Match
- Auto Generate
Note: Match modes only apply to dimensions. They are not used when mapping source properties to Endeca properties.
