DOSP - Dealer Order Submission Process
The weekly process consists of 4 stages.
1. Constraints Distribution - Dealers are informed on constraints to review before placing orders. (A Constraint is a limit placed on specific build configurations or specific models.)
2. Dealer Order Submission - Dealers can order on Thursday, Friday or no later than midnight on Saturday. (You can submit orders earlier but you don't know the constraints.) (Sunday the system is unavailable)
3. The 4-Pass Process - GM will attempt to place each dealer’s orders on Mondays using a 4-Pass process. (At this point a dealer may get more or less than what they were allocated.)
4. Dealer Review - You can review your placed orders for changes or replacements until Tuesday at 9pm ET. That's when the accepted orders are sent to production control.
