schedule margin key

Dear All

Please tell me the meaning of schedule margin key and the purpose of the same.

Dear ,

Scheduling margine key is key for FERT /SEMIFG material where you define the produtction order floats to determine the productiion dates in Production Order /Planned Order .

Here you define certain time set up in workdays which are one of the critiera to arrive your Production Dates (Basic Dates/Schedule Dates-CO02-Production Order header ) .

More Specifically , A schedule margin key consist of folowing days as required in a production order

1.Opening Period : The number of working days between the date that the order is created and the planned start date.

2.Float After Production :The number of working days between the scheduled finish date and the order finish date; used as a float in production scheduling

3.Float Before Production : The number of working days between the order start date and the scheduled start date; used as a float in production scheduling

4.Release Period of the Production Order : The number of workdays between the planned start date of the production order and the date for releasing the

The float before production, float after production and the release period are defined in the scheduling margin key (Customizing for Shop Floor Control, by choosing Operations  Scheduling  Define Scheduling Margin Key). The scheduling margin key is assigned to the material (MRP area in the material master) and is transferred when the production order is created. These values can be changed in the production order in CO02.

You define Scehduling Margin Key in -OPPQ/OPPR and same has been assinged to MMR in MM02 of that FG/SFG material .

Hope this will give u an idea on SMK.

Hi,

Pl. find some information on SMK..

You define the order float in the scheduling margin key, The scheduling margin key is copied from the material master. The float before production or float after production and the release period are defined in the scheduling margin key

For Customizing for Shop Floor Control, by choosing Operations --> Scheduling --> Define Scheduling Margin Key .

The scheduling margin key is assigned to the material ( MRP area in the material master) and is transferred when the production order is created. These values can be changed in the production order.

Hi,

Schedung margin key can be usd in scheduling of production order.

In scheduling margin key you can define floats

Float before ,float after So basically this is Cushioning period to process order.

If you define 1 DAy before & 1 Day after float

In house time is 5 days

If you schedule the order on 15.05.2010 then that case basic start date will be 14.05.2010 Schedule start date will be 15.05.2010 ,

Schedule finish date will be 19.05.2010 ,Basic finish date will be 20.05.2010.

This concept can be used where you want some Cushioning period ,normally in process industry when they wan to start batch they require some time to clean the their equipment that may be 1 day, Also they want 1 Day extra to complte that batch.

Schedule Margin Key

Opening period: Number of workdays subtracted from the order start date to determine the creation dateThe opening period can be used by the MRP controller as an extra time buffer.

The opening period is only used in backward scheduling

The float after production is the number of workdays that are planned as a buffer

between the production finish date and the order finish date. This serves to compensate

for interruptions during production to avoid displacing the order finish date.

If the current date is 13.05.2010 and the Float befor production is 10 days, hence the planned opening date for the planned order will be 03.05.2010

The float before production is the number of workdays that are planned as a buffer

between the order start date and the production start date. By using this float, delays in

material staging do not cause delays in starting production. Additionally, if there are

capacity bottlenecks or delays in an incoming sales order, the production dates can be

brought forward

The system deducts the number of days defined in the release period from the scheduled start of the order and thus determines the scheduled release date of the order

Hi,

Sap Help says,

Scheduling margin Key,

The float before production, float after production and the release period are defined in the scheduling margin key (Customizing for Shop Floor Control, by choosing Operations -- Scheduling--- Define Scheduling Margin Key) . The scheduling margin key is assigned to the material ( MRP area in the material master) and is transferred when the production order is created. These values can be changed in the production order.

You define the following floats with the scheduling margin key:

opening period

float after production (only in the case of in-house production)

float before production (only in the case of in-house production)

release period (only in the case of production order management)

Floats are always maintained in workdays.

Opening period- The number of working days between the date that the order is created and the planned start date.

This time is available for the MRP controller to convert a planned order into a purchase requisition or a production order.

float after production- The number of working days between the scheduled finish date and the order finish date; used as a float in production scheduling.

float before production- The number of working days between the order start date and the scheduled start date; used as a float in production scheduling.

release period- The number of workdays between the planned start date of the production order and the date for releasing the order.

If the order release indicator is set, the production order is released by a background program that takes all dates into account.

Hope this helps you.
