Setting Up Bills of Material

Much of the setup required for outside processing occurs in Bills of Material. You must define outside resources and assign them to departments and shifts. You must also define routings that include operations with outside resources. You can also include supplier-sourced components on your bills of material.

Define Outside Resources

You must define outside resources and link them to outside processing items in order to automatically generate purchase requisitions for outside processing. When you assign outside resources to a routing, you also specify a usage rate or amount that determines the quantity you are requisitioning and/or charging to work in process jobs or repetitive schedules. You must define the following resource attributes for outside resources: See: Defining a Routing. See: Defining a Standard Operation and Count Point and Autocharge Fields

Autocharge

Use this attribute to determine how you charge a resource to a job or repetitive schedule. For outside resources you want to automatically requisition, you choose either PO Move or PO Receipt. Purchasing charges these resources to jobs and repetitive schedules when you receive against purchase order lines linked to the resources.

In addition, Purchasing enters move transactions when you receive against purchase order lines linked to PO Move resources. Purchasing moves the outside processed assemblies to Queue of the next operation unless you're at the final operation. In this case, Purchasing moves the assemblies to the To Move step of the last operation. You should choose PO Move and/or PO Receipt based on your physical flow. You can have only one PO move resource per operation. You can override the autocharge of a resource when you assign the resource to a routing.

You can manually link a purchase order line to a job or repetitive schedule and charge any PO Move or PO Receipt resource on the routing.

Outside Processing Item

Use this attribute to associate an outside resource with the outside processing item you are buying from a supplier. When you enter a move into Queue of an operation with an outside resource, Work in Process automatically requisitions the outside processing item associated with the outside resource.

You may not necessarily want to link an outside processing item with every outside resource. As discussed earlier in the "Chemical Analysis" resource example, you might want to charge a resource to a job or repetitive schedule but not create requisitions with each move transaction.

UOM

Use this attribute to specify the UOM associated with a resource. In general, the UOM of the resource would be quantity based such as EA for each plated item since this is the likely unit of measure for items on purchase orders. However, you can use a time based UOM if you purchase a quantity of time, such as plating machine hours. If your resource UOM is time based, you can also schedule the resource and include the resource in capacity plans. If the UOM is quantity based, you can define a separate resource for scheduling your jobs or repetitive schedules and for including outside resource load in capacity plans.

Purchasing always purchases items linked to outside resources using the outside processing item's UOM. Purchasing always charges items to jobs or repetitive schedules using the resource's UOM.

Standard Rate

Use this attribute to control whether you charge an outside resource to a job or repetitive schedule at the standard rate of the resource or whether you charge the job or repetitive schedule at the actual purchase order line price. If you charge at standard, then Purchasing writes any variance between the purchase order actual and the resource standard cost to the purchase price variance account of the resource at purchase order receipt. If you charge at actual, then Work in Process writes any variance to the outside processing elemental variance account associated with the job or repetitive schedule you are charging at job or period close. You can override whether you charge a resource at standard when you assign the resource to a routing.

Absorption and Variance Accounts

You must define a purchase price variance account for each outside resource you define. This account defaults from the organization's purchase price variance account. You must also define an absorption account for each outside resource. The absorption account defaults from the organization's receiving account, which Purchasing debits when it receives an outside processing item and subsequently credits when it delivers the item to work in process. Purchasing debits the outside processing account associated with the accounting class of the job or repetitive schedule when it delivers the item to work in process.

Cost Element

When you define a resource with an Autocharge of either PO Move or PO Receipt, Bills of Material automatically defaults Outside Processing as the cost element. However, you can also charge PO Move and PO Receipt resources to any of the other cost elements, including Material, Material Overhead, Resource, and Resource Overhead.

Assuming you use the Outside Processing cost element, the assembly cost rollup inserts the outside resource standard cost into the outside processing cost element for the assembly. Purchasing charges the outside processing cost element when you receive against purchase orders. Work in Process credits the outside processing cost element at standard when you complete assemblies. See: Overview of Work in Process Costing.

Costed

Enter Yes to include an outside resources in your cost rollup. You can enter No if you want to use a resource for other purposes such as scheduling. You cannot override this attribute on the routing.

Default Basis

You can define a default basis of either Lot or Item, which you can then override on the routing. Enter Lot if you schedule or charge the resource once for each job or repetitive schedule. Enter Item if you schedule or charge a resource based upon the job or repetitive schedule's assembly quantity.

You might enter Lot for outside resources that represent services such as setup and teardown. Other services for which a supplier charges based on the assembly quantity should have a basis of Item.

Resource Unit Cost

Use the resource unit cost to define the standard cost per UOM for a resource. Bills of Material uses this standard along with the standard lot size, usage rate or amount, and basis on the routing when it calculates the outside processing elemental standard during an assembly cost rollup. Purchasing also charges jobs and repetitive schedules using this cost when you receive against outside processing items linked to outside resources that charge at standard.

As your buyer negotiates price changes with your suppliers, he maintains the List Price attribute in the Items window. Purchasing defaults this price when it creates requisitions and purchase orders (except if you set up a blanket, in which case Purchasing defaults the price on the blanket.). As the actual purchase price varies from the standard resource cost, you create variances. You can reduce these variances by keeping the resource's unit cost in line with the list price for the outside processing item in the Items window. See: Defining Items and Defining a Resource.

Define Departments with Delivery Locations

You must define departments with outside resources and valid delivery locations before you can include outside operations in your routings. You cannot associate an outside resource with an operation on a routing unless the resource is assigned to the operation's department and the department has a location associated with it.

Work in Process passes the department location to Purchasing as the Deliver-To location when requisitioning outside processing items. Purchasing requires a Deliver-To location when you receive outside processing items and deliver them to the shop floor. See: Defining a Department

Define Routings

Use the Routing window in Bills of Material to associate outside resources with assemblies requiring outside processing. You can define a routing with one or more outside operations that each include one or more outside resources. When you associate an outside resource with an operation on a routing, you set the usage rate or amount for that resource. Work in Process uses the routing to calculate the requisition quantities and to schedule jobs and repetitive schedules. Cost Management uses the routing to calculate the assembly's standard cost. See: Creating a Routing.

Calculating Requisition Quantities for Outside Processing Unit Type of Resource

When Work in Process requisitions an outside processing item with a Outside Processing Unit Type of Resource, it uses the outside resource's usage rate or amount and basis to calculate the requisition quantity.

If the basis is Item, Work in Process requisitions the usage rate or amount times the move quantity each time you move into Queue of the outside operation. For example, if you have an outside resource with a UOM of HR and a usage rate or amount of 10, and you move five assemblies into the outside operation, Work in Process requisitions 50 HR of the outside processing item linked to the outside resource.

For outside resources with a basis of Lot, Work in Process requisitions the usage rate or amount of the resource when you move the first assembly on the job or repetitive schedule into Queue of the outside operation.

Calculating Requisition Quantities for Outside Processing Unit Type of Assembly

When requisitioning items with an Outside Processing Unit Type of Assembly, Work in Process does not extend the assembly move quantity by the usage rate or amount.

For outside resources with a basis of Item, Work in Process requisitions the move quantity each time you move into Queue of the outside operation.

For outside resources with a basis of Lot, Work in Process requisitions a quantity of 1 when you move the first assembly on the job or repetitive schedule into Queue of the outside operation.

Job/Schedule Assembly Outside Processing Item Outside Resource Transaction Quantities
Move Qty UOM Outside Processing Unit Type List Price UOM Basis Usage Rate or Amount Standard Rate UOM Req, PO, Receipt Quantities Job/Schedule Charge Amount
50 EA Assembly $1 EA Item 10 $1 EA 50 EA (50 x 10) @ $1 = $500
50 EA Assembly $1 EA Lot 10 $1 EA 1 EA (1 x 10) @ $1 = $10
50 EA Resource $1 HR Item 10 $1 HR 500 HR (500 HR @ $1) = $500
50 EA Resource $1 HR Lot 10 $1 HR 10 HR (10 HR @ $1) = $10

Work in Process Scheduling

Work in Process schedules all resources in a routing with Scheduling set to Yes and with a time based unit of measure. If you are requisitioning outside processing items for outside operations with units of measure that are not time based, you may want to add resources with time based units of measure to the routing to accurately schedule the outside processing work. You can also include time based outside resources in capacity planning. See: Overview of Work in Process Scheduling and Creating a Routing.

Define Supplier-Sourced Components

You can define supplier-sourced components on bills of material by choosing a supply type of Supplier. Work in Process prints the supply type on several reports including the Pick Lists and the Routing Sheets. This information signals to your supplier the components that he is responsible for supplying. Master Scheduling/MRP does not plan these components.

Whether you associate a standard cost with these supplier-sourced components in the item master depends on how your supplier charges you for the item. If your supplier includes the component costs in the price of his service (the outside resource), then you would not want to also include the cost in the assembly's bill. For example, if your plating supplier provides zinc as part of his plating service, then you might include zinc on your bill at the outside operation but include the cost of zinc in the plating resource. See: Creating a Bill of Material

Cost Rollup

The cost rollup uses the outside resource's usage rate or amount, unit cost, and basis to calculate the outside processing costs for the primary routing of each assembly. Lot based resources are allocated across the assembly's standard lot size in calculating the assembly's standard cost. Assuming you associate the Outside processing cost element with your outside resources, the assembly cost rollup inserts the outside resource costs into the outside processing cost element. See: Rolling Up Assembly Costs
