Labor time in production order scheduling

[former_member600146]

I have a an operation where labor time is 20 mins and there is no machine time. I have created a work center with labor category. In scheduling view where in need to maintain the formula ? In 'Processing formula' or 'Teardown formula' or 'Other formula'? I have maintained 20 mins in routing under labor time and machine time is empty. Please see the attachments.wc.pngrouting-labour-time.png

Hi,

I see that if I maintain the labor formula in processing field then the labor time from routing is considered for scheduling. Closing the thread in case you do not want to add anything further.

I noticed something odd. When I schedule the routing for every operation about 2.5 min coming extra. I have checked the config there no reduction level maintained. In work center the capacity is 100%. What could be the reason for the extra minutes? Any idea?

Thank you both for the excellent documents but there is still one thing unclear to me.

I have maintained formula in 'processing' field and my formula contains only one parameter Y801 (copy of SAP_02).

case1: I have maintained 20 min under 'Machine' and 20 mins under 'Labor' in routing. What is my operation time? 20 min or 40 min?

case2: I have maintained 30 min under 'Machine' and 20 min under 'Labor' in routing. What is my operation time? 30 min as it is larger of the two or 50 min?

Hello,

You can do the scheduling of routing and check the results

Or you can create the production orders and check the scheduling results and come back with specific query if you have any.

Better create a production order and check. That is the best advise i will give you . That is not going to take at least half an hour. So that you will see real time data and consequence and your knwoledge improve right. please go ahead with creating the order.

Thnx Brahmakar.

In routing I have not entered any time under 'Machine' and have only entered time under 'Labor'.

In this case also I need to maintain formula under 'Processing'?

In which case I will use 'Other' in scheduling view?

[rupesh_brahmankar3]

Hello,

Correct, use it as Processing and in routing maintain the labor time.

In SAP Plant maintenance Scheduling tab- SAP0004(Other formula field) can be used.

For more details refer SAP help document on it

Hi Brahmkar,

I have used category 003. Where I need to maintain the formula in scheduling view?

Is it Setup(i dont think so), Processing , Teardown (mainly used for break down) or Other ?

[rupesh_brahmankar3]

Processing

[former_member600146]

Let me put the question again: As I am entering the time in routing under labor, hence in work center under which category i need to enter the formula ?

Is it Setup(i dont think so), Processing , Teardown (mainly used for break down) or Other ?

When we user 'Other'? Can I use 'Other' in my case?

[rupesh_brahmankar3]

Hello,

As you have created work center with category as 002 and which you want for scheduling and costing then use it in Processing formula like SAP003.

Hi,

In your case teardown time to be maintained to calculate labour time during production order scheduling.

The system calculates the duration of the operation segments that make up the execution time (setup, processing and teardown) using formulas. You can enter a separate formula for each of these three operation segments in the work center. You can use the following parameters in the formulas:

• standard values depending on the standard value key
• formula constants from the work center
• general operation values, such as
• lot size
• base quantity
• number of splits (partial lots)

Values from user-defined fields in the operationIf you have not maintained a formula or standard values for a formula to calculate duration times for one of the three operation segments (setup, processing or teardown), the system calculates for the corresponding operation segment using a duration of zero.

The formulas used to calculate the duration are not the same as those used to calculate capacity requirements. They are maintained separately in the work center. The system can only calculate the duration of the individual operation segments if you have maintained the formulas on the Scheduling screen in the work center.

To calculate the setup, processing and teardown times of operation, the system always uses the smallest unit for the standard values. If you want the times to be calculated using a larger unit, you must change the smallest time unit of the standard values.

Hi Rajib

Labour time is the actual time is being neeeded for performing a work.

Tear down time is the time during which the machine has been under breakdown needed removing parts and fix it again.

I hope it clear now for you
