SAP ERP Financials - Controlling: 5 Stepsto Understanding Product Costing- Part 3Quantity Structure

Posted by Tanya Duncan Jan 2, 2013

Product Costing, part of the Controlling module, is used to value the internal cost of materials and production

for profitability and management accounting. Product Costing is a niche skill. Due to costing's high integration

with other modules, many people avoid it due to the complexity. This 5 part blog will seek to simplify Product

Costing.

The third step in understanding the basics of product costing is Quantity Structure. Quantity Structure enables

you to calculate the cogs of goods manufactured and cost of goods sold for products based on the BOM and

Routing (PP) or Master Recipe (PP-PI).

Prerequisites:

Master data is created Material Masters (including MRP, Accounting, Costing views) Bill of Materials Work Centers (with Cost Centers and Activity Types) Routings (Production Planning) OR Master Recipes (Production Planning- Process Industries) Production Versions (optional) Product Cost Collectors (PP-REM - Repetitive Manufacturing)

Overview:

Quantity Structure is an important concept in Product Costing because it is a key integration point between the

Finance and Logistics modules in SAP. There are several components of Quantity Structure.

A material master is created for each product with a unique fit/form/function in a plant. The material master

contains many views including Material Resource Planning (MRP) views, Accounting views, and Costing

views. Two costing-relevant fields on the MRP 2 view are procurement type and special procurement key.

The procurement type field indicates if a material is produced internally, purchased or both. The special

procurement key further designates if a material is subcontracted, a phantom, purchased from another plant,

etc. It is important that these two fields are correct when costing a material.

For each internally produced material, a bill of materials (BOM) is created. A BOM contains the component

materials and quantities required to produce a finished or semi-finished good. The material cost of a product is

calculated using the standard or moving average price of the BOM components depending on the price control

(S for standard, V for moving average).

SAP ERP Financials - Controlling: 5 Steps to Understanding Product Costing- Part 3 Quantity Structure


A work center (PP) or resource (PP-PI) identifies a machine or work area where a production process is

performed. Each work center or resource utilizes a standard value key which is a unique set of activities related

to a work center. I previously discussed activity types in part 1 of this blog series.

In addition to a BOM, a routing or master recipe is created to indicate the processes required to produce

a material. In Production Planning (PP) manufacturing, a routing is made up of a series of operations that

include work centers and activity quantities which define a production process. In Production Planning- Process

Industries (PP-PI), a master recipe is used for batch-oriented process manufacturing. A master recipe contains

the processes required for producing a material including the resources (instead of work centers) required for

production.

Repetitive manufacturing utilizes rate routings and product cost collectors. Product cost collectors are created

for each production version (see below) and capture costs per period rather than per order.

If there are multiple ways to produce a material including different material combinations or activities,

production versions can be used. Production versions indicate a combination of a BOM and routing or master

recipe required to produce a material. The first production version should be the most frequent or realistic

Relatable Example:

Let's say we are using Product Costing to value our inventory in a cookie baking shop. This will help us value

our cookies (finished good), frosting (semi-finished good), and baking items like eggs, milk, and sugar (raw

materials).

In order to calculate costs, we need a list of ingredients (Bill of Material) and a recipe of steps to follow (Routing

or Master Recipe). There may be several ways that we can bake the same cookie by substituting ingredients or

baking in different ovens, so we can have several versions of our ingredients and recipe (Production Version).

In order to accurately calculate costs of producing our cookies, we need to define the places where baking

activities occur (work centers or resources).

For example, we may use a refrigerator, mixing station, oven, cooling station, and packaging station. Each

would be considered a work center, and we assign different activities like labor and overhead to each work

center. The work centers and amount of each activity are indicated in our recipe (Routing or Master Recipe) as

operations. Using the costs for each ingredient (Material Master) in our ingredient list (BOM) and the rates for

activities in our recipe (Routing or Master Recipe), we can calculate the cost of producing a cookie.

Further information: Material Master MRP settings are crucial in product costing with quantity structure. You must re-calculate and release costs to reflect changes in production data like BOMs, Routings or

Master Recipes, Production Versions.

In my next blog, I connect the concepts of cost center planning, activity rate calculation and quantity structure

to the costing process. This blog includes executing a costing run, costing an individual material, and marking

and releasing costs.

Thanks a lot Patrica,

Today I learned something new costing process.

Thanks again.

Hi Ram,

Yes, you can use multiple production versions to cost. You will use "mixed costing" to do this. It first needs to

be set up in configuration. The menu path is Controlling > Product Cost Controlling > Selected Functions in

Material Costing > Mixed Costing. (There are two configuration steps.)

Once you have the configuration in place, you must create a procurement alternative for each production

version that you want to use in the costing. Then you create mixing ratios to determine what proportion of the

cost of each production version should be used in the final costing.

For example: Production version 1 -- used 20% of the time Production version 2 -- used 50% of the time Production version 3 -- used 30 % of the time

So you create 3 procurement alternatives -- one each for production version. (This is transaction CK91N.) Then

you create the mixing ratios. (This is transaction CK94.) Procurement alternative 1 (for production version 1) = 20% Procurement alternative 2 = 50% Procurement alternative 3 = 30%

Now when you create a cost estimate, if all the master data fields have been populated correctly, your cost

estimate will take 20% of the cost of production version 1, 50% of the cost of production version 2, and 30% of

the cost of production version 3.

The itemization view of the cost estimate will have three lines, one for each production version, instead of the

lines that make up the BOM/Routing. Each line will have its own cost estimate. These will have status "KA"

-- they will never be released (only the top level cost estimate, the material level, will be released). And the

quantity will represent the percentage. You can drill into the details, just as if they were sub-BOMs.

This is just an overview of mixed costing -- hope it helps!

Dear Tanya,

Very productive blog.Great Job.

I have a question, Does we can cost the finished product with multiple production versions ?

Please clarify.

Thanks,

Ram

Patricia Brainard in response to baburao j on page 5Oct 22, 2013 11:11 PM

Hi Baburao,

That depends on how you are populating COPA and how you are doing reconciliation. If you are comparing

COPA records that were created from FI postings, then both systems should match. But remember that it is

possible to create COPA records manually that look like postings from FI. These will not have FI postings to

match. You might also have custom programs that are supposed to be creating both entries -- FI and COPA --

but one posting or the other failed. Or a COPA posting might have been reversed when the FI posting was not

reversed.

Also, COPA postings that did not originate with FI (such as a COPA posting from an SD invoice) will not

necessarily tie to FI.

So you have to look for how the data got into COPA.

Best Regards,

Patricia

Hi Tanay,

what are the causes to make difference between copa and fi ?

Yours faithfully,

Baburao.

Tanya Duncan in response to Symbat Issabayeva on page 6Feb 11, 2013 2:27 PM

Hi Symbat, we need to value inventory for our balance sheet and income statement. We want to understand

how profitable we are by product, customer, plant, etc. Understanding your variable costs also helps you

determine pricing so you can lower costs but still remain profitable.

Symbat IssabayevaFeb 10, 2013 7:08 PM

Dear Tanay,

Thanks to your post it is really helpful, but I have problem with understanding 'Why we need to keep

information about the costs of products and materials?'

thanks in advance

Yours faithfully,

Symbat
