Oracle Enterprise Asset Management utilizes Work Orders to create demand for asset maintenance. Operations within Work Orders are completed using the Work Orders’ associated material and resource requirements. Cost savings and work management efficiencies can be achieved by generating future, planned work activities, and then using a planning
process to balance the work loa for resource management.

The process is as follows:
First, a Master Demand Schedule is created. This Master Demand Schedule is then attached to Material Requirements Planning (MRP) options. MRP is launched, creating planned Work Order suggestions. You can use the Planner Workbench to
implement the suggestions into purchase requisitions or maintenance Work Orders. Using the Purchasing AutoCreate feature, purchase orders are created from the  requisitions. After the purchase orders are received into inventory, you can issue material into a maintenance Work Order.

eAM Planning

Oracle eAM utilizes Material Requirements Planning (MRP) to calculate net material requirements from gross material requirements, by evaluating:
■ the master schedule
■ bills of material
■ scheduled receipts
■ on-hand inventory balances
■ lead times
■ order modifiers

Material Requirements Planning then plans material replenishments by creating a set of recommendations to release or reschedule orders for material, based on net material requirements. MRP assumes infinite capacity is available to meet the
material requirements plan.

The following illustration depicts how eAM uses Material Requirements Planning. First, a Master Demand Schedule (MDS) is created. This schedule is then attached to MRP Plan Options. Next, the MRP is launched, creating suggestions for purchasing requisitions. Finally, these suggestions are implemented. They are purchased, and then received into inventory. After the material is in inventory, it can be issued to a maintenance Work Order.
