# Scheduling of Dates in Planned and Production Order

This blog post will throw light on Calculation of Scheduling Start Dates/Time and End date/time takes place in Planned and production orders

What is Scheduling, Methods and its types?

Scheduling:

1. A detail of when and where each operation in the manufacturing process is to be performed or executed.
2. Establishment of an activity timetable which gives at which time to start and/or finish each event or operation comprising any procedure or process.
3. It is an important tool for manufacturing and engineering, where it can have a major impact on the productivity of a process. In manufacturing, the purpose of scheduling is to minimize the production time and costs, by telling a production facility when to make, with which staff, and on which equipment.

Methods:

There are two methods of Scheduling.

a) Basic Dates scheduling – In this scheduling , System will calculate the basic Start and Finish dates based on the timings of material master e.g. In-house Production time, GR processing time, Schedule margin key

b) Lead time scheduling– In lead-time scheduling, System will calculate actual timings based on routing and capacity requirements generated with exact production dates

Types:

Below are the commonly used scheduling types

a) Forward scheduling (Starts with order start date)

b) Backward scheduling (Starts with order finish date)

c) Only capacity requirements

d) Current date

Illustration:

Let us take an example

Case 1:

Material X with In-house Production time – 5 days , SMK – Op. Period =2 days, GR processing time = 1 day

Now, when we create planned order manually, how system will calculate the dates

When we convert planned order to Production order with CO40, it calculated the Start and End date as per planned order

Case 2:

In case of manual order creation where operation segments will be taken into consideration.

Scheduling dates in routing for 1000 EA

Now, create a Production order with CO01 to check which dates system will calculate.

Factors and Customizing affecting scheduling Date/ Time:

1. Scheduling parameters for production order
2. Scheduling type
3. Formula Definition/ formula parameter, which is being assigned in Work center
4. Standard Value key
5. Performance efficiency rate key
6. Schedule margin key
7. Move time matrix
8. Reduction Strategy
9. Shift Sequence
10. Calendar to define working days and non – working days
11. Control key for operations
12. Standard and Minimum queue time
13. No. of Individual capacities
14. No. of splits
15. Minimum wait time etc

Conclusion:  We will will be able to calculate or analyse the scheduling dates of planned order/ production order with  required master data settings and related customizing/factors relevant to our scope.

Very informative and clearly explained.Keep going.

Any illustration with Backward scheduling and system behavior on the same? that will cover all the scenarios as a part of Scheduling I hope.

Just as a suggestion.

Hi Vignesh,

Thank you..!!

Sure, will write on some more scheduling topics in coming days  and thank you for suggestion.

Can i know where I can view below as I tried in Production order unable to find the path.Currently working in S4 1709 release.

Thank you.

Hi Vignesh,

This details can be seen in Extras--> Schedulling.

Can i know whether the same can be see in Production order.

Above screen shot shows that the place of CA02 instead will Production order will handle this?

Thank you

Vignesh V

Yes, in the Production Order operation overview under graphic you may select operation or Gantt chart for the same view

Nice document Amit for the Scheduling.

Hello Phil,

I believe SAP allows us to print and Save Gantt chart in pre-defined formats and not in excel. Hope this helps

You can open a new thread for this query and also raise a ticket to SAP

Hi Amit,

it's very nice document.

I have a issue my basic start date every time showing one day back after scheduling.

But my scheduling type is forward

Hello Amit!!

Actually we are replicating ECC Production Orders to IBP, but just Basic Dates are included, we need the schedulled dates.

Do we need to apply an enhacement? Documents are previously located in ECC/ORDER_EXT staging table in ECC.
