MRP in ERP Explodes Bill of Material (BOM) assuming capacity to be infinite. This results in incorrect date to planned orders and purchase requisition. Does not consider alternate item while exploding BOM. This could result in unnecessary purchase.

If supplier is getting delayed, then it does not move the planned orders to a later date based on material availability. This leads to infeasible plan. Does not move the o rders to alternate resource if primary resource is over loaded. This needs to be done m anually. Does not move the o rders to alternate routing if primary routing is not available. This needs to be done m anually. Commitment date provided is not reliable as it assumes capacity to be infinite. Does not consider additional resource like tools and fixtures while planning. Many times they may not be available. Does not pull similar items together so that setup time is reduced. This needs to be done manually. Does not short the demand order based on material availability. availability. Does not create a pegging between a demand and supply order. Cannot find out which procurement ultimately feed to which customer orders. Cannot model batch resource like oven or heat treatment where multiple work orders are grouped and processed together. Cannot do what-if to give a promise date to customers.

Planvisage APS Explodes Bill of Material (BOM) assuming capacity to be finite. This results in feasible date to planned orders and purchase requisition

Considers alternate item while exploding BOM. If primary item inventory not available and if alternate item inventory available, then based on configurable business rules, automatically allocates the alternate item inventory. If supplier is getting delayed, then it moves the planned order to the date when the material will be available.

Moves the order to alternate resource automatically based on certain rules if primary resource is over loaded. Moves the order to alternate routing automatically based on certain rules if primary routing is not available. Commitment date provided is reliable as it considers finite material and capacity constraints Considers additional resource while allocating a job to a resource.

Pulls all the similar items together thereby reducing the setup time and increasing the throughput. Shorts the demand order based on material availability. Creates a pegging between supply and demand orders. So any delay in supply immediately will come to know which customer orders will get affected. Can model batch resource where multiple work orders are automatically grouped and processed together. Can do what-if to give a realistic promise date to customers.
