Horizons

[Former Member]

Hello

A very basic question, if you guys can pleas advice me on this:

Can you tell me whats the recommended length of below horizons, or factors to define these horizons:

PPDS Horizon

SNP production horizon

Extended horizon

Deployment horizon

Pull Horizon

Push Horizon

Stock Transfer Horizon

Is there a relation between PPDS horizon and Deployment horizon. Even in case it makes logical sense please let me know the factors to define them to see the whole picture

Thanks in advance

Hi Rahul,

Most of these depend on the business requirement.

I will try to highlight their importance and their logical linkages....

PPDS Horizon - the horizon in which you do your detailed planning, should be greater than or equal to SNP production horizon - typically 2 weeks to 1 month (but depends on the production cycle time, lead time to accomodate changes etc...)

SNP production horizon - Horizon beyond which SNP can create planned orders - should be less than or equal to ppds horizon

Extended horizon - similar to SNP prod horizon, but manual orders can be created in this horizon, one of the two or both can be used

Deployment horizon - this is what you maintain in SNP02 transaction this should be less than or equal to pull horizon

Pull Horizon - Greater than or equal to the deployment horizon (maintained at source location)

Push Horizon - period within which you want to consider your receipts (maintained at source location)

Stock Transfer Horizon - period within which you donot want stock transfer to be created (maintained at destination).

and there is no relation between deployment horizon and PPDS horizon.

Thanks Ashok for your reply and explanation

As you said, the PPDS horizon depends on the lead time, does it mean lead time of RM products required for production or production lead time.

In case you were referring to Production lead time, then in case of two days of lead time, is PPDS horizon of a week is sufficient?

I raised this qst to confirm the best practice for handing over the SNP orders to PPDS orders and which eventually also help me in deployment. As for deployment I need only confirmed / released order and their dates.

Points awarded anyway

Can you give more details on the implications of PPDS and SNP overlap period usually acceptable in such scenarios!

Hi Rahul,

There are a lot of factors which will influence the PPDS horizon...

1. You need to look at the cumulative lead time, right from starting the execution of planned order at the lowest level to the FG planned order leadtimes...

2. How different are your SNP & PPDS PPMs if they are almost similar then your SNP run itself would have created planned orders / preqs for all products and planned capacities also. If they are very different and the components present in PPDS PPM but not in SNP have significant lead time, you have to consider their procurement and production lead times as well in your PPDS horizon.

3. Some plants have a larger PPDS horizon to have sufficient planned orders even in future to enable rescheduling. if there is a shortage towards todays planned order and all componets are avaialble for an order planned for next week, they might want to reschedule the next weeks order and produce today to ensure capacity is not lost...

Similarly there could be many other considerations which would depend on the actual business reqmts and the flexibility required...

To answer your question if cumulative lead time is 2 days and SNP/PPDS PPMs are similar 1 week PPDS horizon should be sufficient. PLease remember PPDs horizon includes your planning time fence as well. so your time fence should be less than a week say 2-3 days.

There is no issue as such with the overlap of the SNP & PPDS horizon. SNP orders in PPDS horizon will be replanned by PPDS. But is there is no specific requrement, you can match the SNP prodn horizon to PPDS horizon, so that PPDS plans inside it and SNP outside it...

Thanks a lot Ashok for your explanation.

In ref to your point 2: We are using PDS in PPDS and SNP. They have same components but different resources. So the lead time for production is same but the min and max lot size of the resources vary, as SNP has cumulative resource.So the lead time is same.

In ref to your point 3: If the orders are rescheduled, wouldnt Deployment orders be wrong if we are considering released order in ATD

Thanks in advance.

Hii Khanna,

Though you have a longer PPDS horizon (say 15days), you can control the deployment of PPDS orders within only a certain number of days (say 5 days) by using the push deployment horizon to 5 days...
