13 Work with Process Industry Costing

This chapter contains these topics:

13.1 Working with Process Industry Costing

Process manufacturing creates a product by mixing, separating, forming, or performing chemical reactions. This is usually a two-step procedure, which consists of a mixing or blending step, followed by a filling or packaging step. This type of manufacturing can also include intermediate steps, such as curing, baking, or fermenting.

Process manufacturing companies create a variety of items, including:

  • Liquids

  • Fibers

  • Powders

  • Gases

Pharmaceuticals, foods, and beverages are specific examples.

A process includes ingredients (equivalent to parts on a work order) and a process routing or recipe. The output from a process includes intermediates, by-products, and co-products.

Output Description
Intermediate The output from an operation that is used as the input to the next operation. There is no cost associated with an intermediate.
By-Product The material produced incidental to or as a residual of the process.
Co-Product An end item produced as a result of the process. There are usually two or more co-products from a process.

The following illustrates an example of a process.

Figure 13-1 Process - Potato Chips

Description of Figure 13-1 follows
Description of "Figure 13-1 Process - Potato Chips"

You define a process item with ingredient relationships. These relationships also determine co-products, by-products, intermediates, and substitutions.

You define the steps that are required to produce a manufactured item with process routings. These routings also determine work centers and labor standards.

    • Type of Operation

    • Yield Percent

    • Cumulative Percent

Field Explanation
Yield % Represents the planned output yield percent for a step. The Planned Yield Update program uses this value to update the Cumulative Percent in the bill of material and the Operation Scrap Percent in the routing. Materials Requirements Planning uses the step scrap percent and the existing component scrap percent to plan component demand.
Cum % Represents the cumulative planned output yield percent for a step. The system uses this value to adjust the operation step scrap percent for the components at that operation step. This enables the MRP system to use the operation step scrap percent along with the existing component scrap percent to plan component demand.

An intermediate is the product of an operation. This product is not the end item of the process, but an input to the next operation. You define intermediates when you need to express them in a unit of measure different from that of the parent item, or when you need to track the quantity of materials at each operation. Only one intermediate is allowed per operation. You cannot define an intermediate for the last operation, because the output of the last operation is the end item of the process.

An example of an intermediate is fermented liquid. The liquid ferments for an extended period of time before being distilled. The resulting liquid is not a finished product. Rather, it proceeds to the next operation.

If you define an intermediate item at a particular operation, you also establish a ratio between the intermediate quantity and the parent quantity. The system uses this ratio for costing the operation. A direct relationship exists among hours, the time basis, parent batch quantity, and intermediate operation quantity.

The system uses intermediate quantities to cost only direct labor hours (cost component B1) and direct machine hours (B3) from the routing. These hours are then used to calculate efficiency (B4) and overhead (C1-C4).

The labor and machine hours at an operation with an intermediate are the hours to produce one unit of measure of the intermediate. The hours are then adjusted in the rollup by the total quantity of intermediates produced at that operation. The following example illustrates the effect of intermediates on costing:

Operation 10

Labor Hours = 5

Intermediate quantity produced = 50 pounds

Hours for costing = 5 x 50 = 250

Form-specific information

The quantity of an intermediate produced at the current step in the process.

Op Seq In routings, this number is used to sequence the fabrication or assembly steps in the manufacture of an item. You can track costs and charge time by operation.

In bills of material, this number designates the routing step in the fabrication or assembly process that requires a specified component part. You define the operation sequence after you create the routing for the item. The Shop Floor Control system uses this field in the backflush/preflush by operation process.

In engineering change orders, this number is used to sequence the assembly steps for the engineering change.

Skip To fields allow you to enter an operation sequence that you want to begin the display of information.

You can use decimals to add steps between existing steps. For example, use 12.5 to add a step between steps 12 and 13.

From Daily PDM Process (G3012), choose Enter/Change Process

Co-products are produced, usually together, as a result of a process routing. They are normally the main products (end items) that are then sold to customers.

A by-product is a material of value produced incidental to or as a residual of the production process. By-products can be recycled, sold as-is, or used for other purposes.

Co-products and by-products are costed using the Feature Cost Percent field.

13.5.1 Example: Feature Cost Percent and Co-/By-Product Costing

In the following example:

  • Cumulative cost = cost this operation + cost of previous operation - cost of the co-/by-product produced in the previous operation.

  • The total of all percentages at an operation cannot exceed 100%.

  • The total of all percentages at the last operation must equal 100%.

Operation Co-/By- Product %
Cost This Operation Cumulative Cost Co-/By- Product Cost
10 By 1 10 100.00 100.00 10.00
20 Co 1 30 100.00 100.00 + (100.00 - 10.00) = 190.00 57.00
Co 2 20 38.00      
30 100.00 100.00 + (190.00 - 95.00) = 195.00      
40 Co 1 60 100.00 100.00 + 195.00 = 295.00 177.00

On Enter/Change Process

  1. Access Process Resource Revisions for Co-/By-products (Option 2).

  2. On Process Resource Revisions, review the following fields:

    • Output Quantity

    • Unit Of Measure

    • Feature Cost Percent

    • Effective

    • Resource Percent

Field Explanation
Output Qty This value is the normal production quantity that is usually manufactured. An item can have multiple batch quantities, for example, liquids that are manufactured in different size vats.

Form-specific information

This value specifies the quantity of each co-/by-product that the process produces. If you use batch bills, this is the quantity that the batch produces.

UM A user defined code (00/UM) that indicates the quantity in which to express an inventory item, for example, CS (case) or BX (box).
Feat Cost % A percentage used by the Simulate Cost Rollup program to calculate the cost of a feature or option item as a percentage of the total cost of the parent.

Enter the percentage as a whole number: 5% as 5.0

Form-specific information

This value is used in Cost Rollup to calculate what percent of the cost, up to and including the operation, that the co-/by-product comes out of, is apportioned to the co-/by-products at that step.

The total of all percentages at an operation cannot exceed 100%. The total of all percentages at the last operation must equal 100%.

Effective The date on which a lot becomes available. The system uses this date for availability and commitment processing to indicate that the lot is available on or after the date that you specify. You must complete this field when inventory first becomes an on-hand quantity for the lot. If you leave this field blank, the system calculates the effective date of the lot by using the value for Effective Days in the Item Branch Master (F4102) or the current date if the value for Effective Days is zero.
Resource % If this option is chosen, this value indicates what percent of the ingredients should be issued separately to co-products and by-products.

Form-specific information

This is used to issue ingredients separately to co-/by-products at work order completion, rather than a total issue for each ingredient.

For co-/by-products at the final operation, their resource percent must equal 100 to issue all ingredients.


13.5.2 What You Should Know About

Topic Description
Feat Cost % When a Co/By-Product has Feature Cost % set to 0.00 %, the Cost Simulation program P30820 retrieves the cost for the Co/By-Product from the cost setup in Item Cost Revisions (P4105). If a cost is defined for the zero feature cost percent Co/By-Product in the P4105, it is utilized by the system and is considered a fixed cost. If zero cost is required, set up the P4105 with zero cost.

13.6 Setting Up the Co-/By-Products Planning Table

This table tells the system which processes to use to calculate the costs of co/by products (Cost %), as well as which processes to use to satisfy MRP demand for co-products (Plan %).

Normally, all demand for co-/by-products is satisfied from process work orders. However, for special circumstances, you can specify, for example, 50% from process work orders and 50% from co-product work orders themselves. To do so, enter less than 100% in the table. The remainder is automatically satisfied by co-product work orders.

Sometimes there will be more than one process that produces a co- or by-product. The cost for the co- or by-product from each process can then be allocated using the Co/By-Products Planning Table. This allows for assigning a weight to the costs from each process. For example, you may have a co-product that is produced by two processes. One process is the normal manufacturing process used 90% of the time. A second process is only used 10% of the time for rush orders, but the costs are much higher to produce this process. In the Co/By-Products Planning Table, the cost % is set to 90% for the first process, and 10% for the second. This allows the co- product's standard cost to reflect the extra costs that are incurred 10% of the time.

Even if all demand for co-/by-products is satisfied from process work orders, you must set up the co-/by-products planning table with a feature cost percent equal to 100. This ensures that the rollup calculates the costs of co- and by-products correctly.

Field Explanation
Co/By-Product A number that the system assigns to an item. It can be in short, long, or 3rd item number format.
Process Item This field indicates whether this is a process from which the co- or by-product is produced or a regular parent item.
Plan % The percentage of demand for a specified feature based on projected sales. For example, a company might sell 35% of their computers with a standard keyboard and 65% of them with an extended keyboard, based on customer demand.

The Material Planning system uses this percentage to accurately plan for a feature's component items. Enter percents as whole numbers: 5% as 5.0. The default value is 100%.

Cost % A percentage used by the Simulate Cost Rollup program to calculate the cost of a feature or option item as a percentage of the total cost of the parent.

Enter the percentage as a whole number: 5% as 5.0

Form-specific information

Used to calculate the cost of a co-/by-product when it can be produced from more than one process, or from a combination of a process and a work order. This value determines what percent of the cost of the co-/by-product is allocated to the selected process.

When you run the Cost Rollup program (P30820), the system rolls up all of the costs for a process, as in the roll up of a discrete item. However, the process rollup involves more than a single end item, and therefore, the system must calculate costs for co- and by-products.

You can set the Process Manufacturing processing option for P30820 to 1 to instruct the system to calculate costs for co- and by-products. When this processing option is set, the program divides the costs for the process into the co- and by-products according to the co- and by-product output quantity set up in the Process Resource Revisions screen (3002P). This gives the cost for the co/by product as it is produced in this process. The program then looks at the cost percentages in the co/by products planning table to allocate the cost from each process this co/by product is produced by to come up with a standard cost for the co/by product.

You can use the Co/By Product Recalculation processing option to indicate that the costs of Co/By Products used as ingredients/components should not be cleared and recalculated.

When you use costing by work center, the system generates the simulated costs for Process and Co/Bys at the work center level.

13.8.1 What You Should Know About

Topic Description
Displayed costs This program calculates the cost associated with each cost component in the same way as the Simulate Cost Rollup program.

13.8.2 Processing Options

See Section 23.7, "Costed Routing Inquiry (P30208)."

13.8.3 Cost Extras

Cost Extras for a process are treated differently due to the fact that they are not associated with a particular step of the process. Feature cost percentages are not used for distributing X costs (cost extras) that are entered on the process. Instead, the program determines the total of the NET ADDED B1-C4 costs for all of the co- and by-products, then determines the percentage of this total each co- and by-product comprises, and then uses this percentage to allocate the X cost.

When you use costing by work center, you can enter cost extras for a process only at the work center level. The program applies the extra cost to the cost of the Co/Bys of that particular step.

13.8.4 Cost Extras (X Cost) on Ingredients

  • If an ingredient that goes into a process has cost extras (X costs) built into it, these cost extras are allocated to the co- and by-products the same way the ingredients are allocated using the sequence where the ingredient is consumed, and the feature cost percentage of the Co/By product.

Description of Figure 13-17 follows
Description of "Figure 13-17 Enter/Change Bill screen"

Review the following fields:

  • Quantity Per

  • Fixed or Variable

Field Explanation
Quantity Per The number of units to which the system applies the transaction.

Form-specific information

A number that indicates how many components you use to manufacture the parent item. A quantity of zero is valid. The default value is 1.

F V Indicates if the quantity per assembly for an item on the bill of material varies according to the quantity of the parent item produced or is fixed regardless of the parent quantity. This value also determines if the component quantity is a percent of the parent quantity. Valid values are:

F – Fixed Quantity

V – Variable Quantity (Default)

% – Quantities are expressed as a percentage and must total 100%

For fixed quantity components, the Work Order and MRP systems do not extend the component's quantity per assembly value by the order quantity.

For Process Manufacturing, the system stores percent components. Therefore, the system treats zero batch sizes like variable quantity components, and treats batch sizes greater than zero like fixed quantity components.
