Project Requirements Planning for Multiple Plants

Project requirements planning, like MRP in general, can encompass more than one plant or facility. The project-specific components that are on the parts list for a work order on the work breakdown structure might be located at a branch/plant other than the plant in which the project is being run. In this case, you must link the project-specific item at the other branch/plant to the project branch/plant by defining an interbranch relationship.

Components that come from a different branch/plant are treated as purchased items. To specify that the supply branch should meet the entire demand, set up the branch relationship so that the supply branch is defined with a source percentage of 100 percent.

When you run the Master Planning Schedule - Multiple Plant program (R3483), it creates messages for replenishment orders. When you process these messages, the system creates transfer orders. Transfer orders satisfy project demand for components by using inventory from the supply branch. To meet the demand at the supply branch, the system creates work orders.
