Identifiers are the way MITS Discover groups together and sub-divides information in its hypercubes. They generally match the names used in your ERP. Examples would be Sales Rep, Warehouse, Product Category, etc.
Every MITS Discover report is made up of a grid which contains horizontal rows and vertical columns.
The vertical columns in MITS Discover reports are populated with accumulators. These are the values MITS has collected or calculated from the data within your ERP.
The horizontal rows in a MITS Discover report are broken down by identifiers. These are the logical buckets used to sub-divide the accumulators.
In the report pictured below, the horizontal breakdown is based on a Location identifier.
The company totals are displayed in the top row, and the individual Location totals are displayed in the rows beneath.
To gain a deeper understanding of these numbers, we can drill down by another identifier within the hypercube and break them down further. That is to say, we can further sub-divide the numbers by another identifier. In this case, we'll use Product Group.
Identifiers are part of each hypercube's configuration. Not all hypercubes have the same identifiers, but when possible the same identifier is called the same thing across all of the hypercubes.
How the identifiers are arranged and which identifiers are available for further exploration under the previous identifier is called a drill down path. These are also part of the cube configuration.
For more about navigating drill down paths, see the article called "Modifying the Drill Down Path".
