Difference between Plannnig Horizon and Production Horizon

[Former Member]

Hai Can somebody explain me the difference between "Planning Horizon and Production Horizon"?

Here is the text that led me to this question:

"If the <b>Production Horizon</b> of SNP is smaller than <b>PP/DS horizon</b>, the <b>planning horizons</b> of SNP and PP/Ds overlap with each other." In this horizon, SNP determines the receipts with most cost effective sources of supply and lot sizes and PP/DS receipts generated by SNP in more detail.

<b>SNP production horizon:</b>

Time period, during which Supply Network Planning (SNP) does not plan production; that is, does not create any SNP planned orders. SNP moves production to the first day after this horizon. SNP deletes all unfixed SNP planned orders from previous planning runs within this horizon. In contrast to the extended SNP production horizon, the user cannot also create SNP planned orders during this horizon.

<b>Production Planning and Detailed Scheduling horizon:</b>Time segment in which Production Planning and Detailed Scheduling (PP/DS) can automatically create, change, or delete receipts.

The duration of the PP/DS horizon is specified in calendar days; it begins on the current date and continues for this number of calendar days into the future.

Outside of the PP/DS horizon, receipts can only be planned manually in PP/DS.

<b>extended SNP production horizon:</b> Supply Network Planning (SNP) (SCM-APO-SNP)

Time period, during which Supply Network Planning (SNP) does not plan production; that is, does not create any SNP planned orders. SNP moves production to the first day after this horizon. This horizon is an extension of the SNP production horizon. However, in contrast to the SNP production horizon, the user can manually create SNP planned orders in this extended horizon in interactive Supply Network Planning.

Hai Uma Maheswar,

Thanks for the reply. What I need is the difefrence between PLanning horizon and Production horizon.

Thanks for your time.

check the following entries in Product master

The SNP production horizon is maintained on the SNP 2 tab page in the product master (transaction /SAPAPO/MAT1).

It also appears in the PPDS tab page along with PPDS horizon

The PPDS Planning horizon and PPDS Production horizon are the same. PPDs only plans inside this Horizon.

What is outside the SNP production Horiozon lies in the SNP planning horizon. Actually thought the name is a bit misleading - SNP does not plan anything inside the production horizon.

If you do not enter a value or you enter the duration 0 for the PP/DS horizon, the system automatically uses the SNP production horizon as the PP/DS horizon during planning. Therefore, the PP/DS horizon is exactly the same length as the SNP production horizon and this means that the SNP and PP/DS planning periods follow on from each other seamlessly and without overlapping.

If the SNP production horizon is smaller than the PP/DS horizon, the planning horizons of SNP and PP/DS overlap. SNP and PP/DS can both use this overlapping period for planning.

A gap between the end of the PP/DS horizon and the start of the SNP planning period is a time segment that is neither planned by PP/DS nor SNP. This can lead to inconsistencies.

So think of two lines - one with its right side shaded(PPDS) and the other with its left side(SNP) shaded. Depending on where you place these lines the shaded sections get planned. how you get the two regions to mesh will ensure the effectivity of your plan

you can also get a better understanding looking at the product view screen and changing the product master values for the horizons and running heuristics
