Suppliers and their products are initially set up as part of the store configuration process. Suppliers may then be associated to an event which makes their products available for selection. An supplier marked as "exclusive" will automatically be associated to an event, and additional suppliers may be added manually based on which suppliers are participating in the event. Keep in mind that suppliers may be simply subsets of your own products or they may be third party companies. Two main reasons for separating certain products out by supplier include:
1) The labor schedules for any labor are different (for example, forklift labor has different ST/OT schedules than display labor). A single supplier may have a single labor schedule; so if products have different labor schedules, they would be configured as separate suppliers in Boomer.
2) The products are not used the majority of the time and so their availability within an event needs to be controlled independently.
