scheduled dates and basic dates in production order

[Former Member]

Hi all,

one basic thing I want to know about scheduling.

when I m going to create a Production order the Scheduled dated and Basic dates are not coming according to the time mentioned in the Material master( Inhouse production time ).The duration is not matching with Routing data also.

I just want to know How the system calculates the Scheduled dates and Basic dates and which data it considers for calculating the scheduled dates.

Cheers

Hi Akki,

For schedule date - The data mentioned in routing is taken to calculate the scheduling date.

Basic dates - for basic dates ( Inhouse Production days + GR processing time + Flots in schedule Margine key(Flot aft Production)) is considered

Also its depend on which scheduling type you are selecting at the time of order creation

Hi Akkie,

there is a very good doc in sap help , if you go through this U will understand the whole process.

Date Determination when an Order is Created

Use

The determination of dates depends on the order creation type. A production order is created by

Converting a planned order into a production order

Creating a production order manually

Features

Converting a Planned Order into a Production Order

If material requirements planning has already created a planned order for producing the material, the basic dates are copied from the planned order and the order start and finish dates are determined in a new scheduling run. If necessary, reduction measures are carried out.

Creating a Production Order Manually

If no planned order exists and you create the production order manually, the scheduling type determines which basic dates you have to enter.

If you enter both basic dates, the system tries to adhere to these dates when carrying out forwards or backwards scheduling. If necessary, the system also carries out reduction measures.

please go through the doc in saphelp.

Dear

1.Basic finish(end) - inhouse production = basic start

2.Finish (end) time + float after production= Sheduled finish time

Start + float before production=Sheduled start time

In-house production time is used to calculate basic dates & floats from schedule margin key is used for lead time scheduling.

1)Bsc start - this is the date on which u want to start your work... ( no calculation is involved)

2)Basic fin. - this is the date on which u want to finish your work. ( Priority type can influence this date..depend on priority type. which u have selected in order header.)

3)SchedStart - this is the start date of work as per system .. this date is totally depend on scheduling type..

example - 1 in forward scheduling it remain fixed and sched finish date & basic finish date would be varying according to the work hours in operation.

4)Sched.Fin. - this is the finish date determined by sytem as per the scheduling type..

example-1 - if scheduling type is backward, then basic fin. and sched fin date would be same. and sched start would be shifted according to the work hours in operation.

note - in the case of current scheduling both type(basic and sched.) of start & finish dates remains same... as per the work hour it may overload the workcenter capacity or it may not

1. Call Date dosn't influence bsc and schd. dates.

2. Basic starts dates would equal to plan date of maintenance call object ( because this is only the due date)

3. Again Basic end dates are depent on Priority type( what we have selected in Maintenance plan) & scheduling types as i mentioned in earlier reply.

4. scheduled start/end dates depends on total work hours in tasklist and scheduling types.

note - If we have asssigned maintenance packages to the task list and using strategy plan...

then Order basic start date would be govern by Initial buffer in mantenance package

and basic end date would be govern by subsequential buffer in maintenance package.

New basic start = Plan Date - initial buffer

new basic finish = plan date + subsequent buffer.

the unit of these buffer is in days.
