Snapshot Tasks
Once MRP_SYSTEM_ITEMS is loaded, then all other tasks can proceed. Each of the following tasks is responsible for creating a set of files that correspond to the database tables:
- Capacity information: loads job resource requirements and capacity resource information
- Delete: deletes data from relevant MRP tables which belongs to the previous plan
- Demand information: loads independent gross requirements and material reservations
- Inventory information: loads information regarding inventory lots
- Item information: loads inventory items, primary suppliers, item categories, item classifications, quantity on hand and cost information
- MPS orders information: loads MPS planned orders
- MRP orders information: loads MRP firmed planned orders
- Purchasing information: retrieves supply information regarding purchase orders, purchase requisitions, intransit shipments, intransit receipts and purchase orders in receiving from the database
- Safety stock: loads time-phased safety stock information
- Substitute items information: loads substitute items
- WIP and BOM component information: loads BOM structures, pending ECOs, component requirements from discrete jobs, repetitive schedules, and non-standard jobs; calculates low level codes and checks loops introduced by both WIP components and BOMs
- WIP information: loads discrete jobs, non-standard jobs, repetitive schedules and calculates aggregate repetitive schedules
When a given file is complete, each tasks submits a request to the Snapshot Monitor. The Snapshot Monitor then checks the dependency and begins loading the file, for use by the Memory-based Planner.
