WIP in production order

What is the significance of WIP?

Term WIP is normally associated with production. During production process input (ram material cost, processing cost, overhead cost) is consumed and at the end of production finished product is expected. But what if production is not yet completed or production is in process, and then unfinished product is referred as WIP.

WIP is something more thing more than raw material but less than finished product. WIP is in the process of getting converted into finished goods. Once converted into finished goods, it will be sold thereby generating revenue to the company. Hence it’s important for companies to keep close track of wip.

Moreover, it’s legal requirement by income tax department that companies need to report wip in their financial statement. When preparing financial statement (balance sheet and P&L) at the month end, then wip is also calculated and reported in financial statement. Hence calculating wip and updating in financial statement is month end process.

High WIP signifies:

  1. Company is having lot of production going on. May be company received lot of customer orders which are to be fulfilled. Company might be expecting strong order pipeline.
  2. May be company’s production process is a bit slow. May be its taking longer time to convert raw material into finished goods.

Low WIP signifies:

  1. Not much production is going on. May be company is expecting not much orders from customers.

  2. May be company is having lean production (just in time production).

WIP calculation and treatment in account books.

Let’s assume production is going on and below is consumed in production process.

WIP at actuals

Here WIP = Input cost consumed – value of output produced.

At month end, wip needs to be updated in account books. Hence below accounting entry should be generated.

Once production is completed, then any difference between input consumption cost and produced output value will not be referred as WIP rather it be called as production variance.

After production is completed, WIP should become zero and difference will be called production variance. Below document will be posted.

WIP posting

Let’s understand configuration needed for WIP in sap

In SAP, production order is created for production department to work upon. Production order is used to track all the activities of production department.

Production order keeps track of

  • Raw materials are consumed in production and their financial value.
  • Process/ activities performed in production process and its financial value.
  • Estimated overhead cost consumed in production process.
  • Quantity of output produced and its financial value.

Hence, we have all the information needed to calculate wip for the production order. Once we have required configuration in sap then at month end we can calculate and post financial document using some T codes.

Let’s understand wip for below production order.

production order target cost vs actual cost

Above production order can be represented as below:

SAP requires below inputs to be able to handle wip:

# Which cost should be included in WIP calculation?

For example, If I decide that all cost to be included in WIP calculaiton then

WIP = 80+1.6+0+40=121.6

If I decide that overhead cost should not be a part of WIP calculation.

Then WIP = 80+1.6+0=81.6

 

# What % of cost should be included in WIP calculation?

If I decide that 0nly 40% of overhead cost should be included in WIP calcuation

Then WIP = 80 + 1.6+0+(40% of 40) = 80+1.6+0+16 = 97.6

 

# GL account determination for posting WIP document?

After WIP amount calculation, below financial document needs to be posted.

Hence GL account needs to be maintained for WIP a/c (balance sheet account) and Change in WIP a/c (profit & loss account).

 

# Production order goes through various stages. At what stage of production order, WIP should be calculatd and posted?

Configuration steps for WIP calculation in sap

Entire configuration of WIP in sap is basically to answer above four questions.

Hope this is helpful in understanding configuration needed for handling WIP in sap.
