Start date of a production order

[Former Member]

hi,

I have a planned order that I converted to production order by checking the conversion indicator in APO.This production order is to today with 1000PCs. Now, if somebody changes the 1000PCs to 700PCs tomorrow, what happens to the start date of the order? is it rescheduled to tomorrow?? I mean the start date is changed to tomorrow?? The order is supposed to be produced yesterday.

Thanks.

It is drive by strategy profile that you define in Maintain Global Parameters and Defaults in IMG , for Std it is SAP002.

as soon as you save the order , it will be rescheudled as per Strategy Profile like backward and then date will be redetermined.

check setting in IMG for : Maintain Strategy Profiles

Path :Production Planning and Detailed Scheduling (PP/DS)->Global Settings->Maintain Global Parameters and Defaults

Hi Manish,

Thanks for the response. I checked the customization and there are different Schedule orders under the tab: Schedule orders:Strategy profiles.

Interactive Planning

Integrated DS Plng B

Planning Run

R/3 Integration

BAPI

Conversion SNP -> PP/D

Conversion ATP -> PP/D

Capable-to-Promise

Planned Ord. Managemen

I guess I need to look at "Planned order management" . it is defined as SAP002.

When I look at what SAP002 is in strategy profile ( under Production Planning and Detailed Scheduling (PP/DS)->Global Settings-)

there is only creation and change dates. how can I go from here?

In your case you need to check strategy profile for Interactive Planning not Planned order management.

Interactive Planning :

The system uses this strategy profile for manual order changes in

interactive production planning; for example, in the order view, o

in the product planning table.

In interactive production planning,

you can change strategy settings temporarily for the duration of a

session, but you cannot save them in this strategy profile.

Hi Manish,

I am looking at the strategy profile for interactive planning. How do I know what are the settings to change these dates??

Please correct me if I am wrong. I am looking at the same strategy in PPT1 and is the selection under "Desired date"

It's got

Current Date

Earliest date and Specified date.

Is this what guides the start date of production order??

By the way the qty. is changed in R/3 does it still depend on the interactive planning strategy profile in APO?

Can we change a production order in APO?? I thought we cannot once it's status is after released status ( only chnageable whiel in status Created and Released).

Current Date means the system searches for a new scheduling date by starting at the current start or finish date for the operations or order - depending on the planning direction

Earliest date means the system starts at the earliest possible scheduling date. The earliest possible date is todayu2019s date plus or minus the offset time or the start of the planning period. You set the offset time in the strategy profile. You can only use this option in combination with the forward planning direction.

When you combine this option with the scheduling mode search for a slot and a scheduling sequence, you can schedule operations at a resource as early as possible and in a particular sequence.

Desired date means you enter a date in the DS planning board when calling up the Reschedule scheduling function; from this date onwards, the system should search for a scheduling date for the objects.

This option is not relevant for the production planning run.

PS:you can only change the quantity only if the order is not released

Hi Visu,

Dates are determined by your scheduling type, how you wants to schedule that order .

It has options like do backword schedule and depending on the time you define in Routings/PPM it will calculate the time how long it will take and calculate start date.

You have option of backward , forwards etc.

than date from where you do backward scheduling that you can define in current data or earliest data or specified date.

If you select specified date than the date you enter in the screen and do the scheduling as you specified like backward , forward etc.

Changes in Production order depends on status that you can control in R/3 IMG.

Generally once order is release it should not be changed but still you can change this setting in R/3.

Yes you can change PO in APO.

Hi Visu,

In APO as per standard setting you can change Production Order if Prod order category is AC ; means released.

AC PrdOrd (C) Production Order .

Can use transaction code : /SAPAPO/RRP3

If it is release you can't change it.

For release order category is AD:

AD PrdOrd (R) Production order (released).

you can change status setting in R/3 and APO as per your requirement by tcdoe:BS22.

But generally we don't touch std SAP setting , also in R/3 we have user define status profile .

If we have any additional business requirement , will try to map it by User defined status profile and attach it with order type.

So as per Std SAP if order is release you can not change it because it is release to shopfloor and depending on date they will start production.

Hi Manish,

I am trying to understand your reply

"It has options like do backword schedule and depending on the time you define in Routings/PPM it will calculate the time how long it will take and calculate start date.

You have option of backward , forwards etc.

than date from where you do backward scheduling that you can define in current data or earliest data or specified date.

If you select specified date than the date you enter in the screen and do the scheduling as you specified like backward , forward etc."

In my strategy profile, I have Strategy as "Backwards + reverse" and desired date as "Current Date".

From my understanding of your statements above, the system checks PPM and resource to find out the time required to setup and produce and then schedule it on today's date?? or looks for a vacant space in resource from today and decides the end date of operation??

In this case, would there be any change in the start date of the order?? or is it just the end date that changes??

Thanks for a lot for your patient replies.

Yes system will calculate time required for the order based on PPM and than first try to do backward scheduling in your case and if start day of PO falls in past after backward scheduling (depending on resources or material availability) than system will do forward scheduling from the todays date and schedule the order.

Start date and end date may both will change depending on scheduling type .
