|mix type (IS-M-SD)|
Key under which a mix type definition is specified.
Before you can create a mix type definition for an edition or media product, you must create the mix type (e.g. 01 Full, 02 Title inserts only, 03 No inserts etc.).
You must maintain ad pre-print information for each mix type. This means you specify whether or not ad pre-prints (ad inserts) can be combined in this mix type.
