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:
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:
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.

What is Scheduling, Methods and its types?
Scheduling:
- A detail of when and where each operation in the manufacturing process is to be performed or executed.
- Establishment of an activity timetable which gives at which time to start and/or finish each event or operation comprising any procedure or process.
- 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.

Factors and Customizing affecting scheduling Date/ Time:
- Scheduling parameters for production order
- Scheduling type
- Formula Definition/ formula parameter, which is being assigned in Work center
- Standard Value key
- Performance efficiency rate key
- Schedule margin key
- Move time matrix
- Reduction Strategy
- Shift Sequence
- Calendar to define working days and non - working days
- Control key for operations
- Standard and Minimum queue time
- No. of Individual capacities
- No. of splits
- 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.
