Difference between SNP horizon, SNP production horizon and PP/DS horizon

Question

I am new to this world of SCM and confused about SNP horizon, SNP production horizon and PP/DS horizon. May I ask for assistance in garbing the concept using some example flows in business scenarios.
Thank you

Hi Rohit,
SNP Production Horizon is the time horizon in which SNP and CTM (Capable to Match) do not plan production. SNP Production Horizon can be maintained in days, weeks and months.
  SNP Production Horizon can be seen in ‘SNP 2’ tab of product master in APO
For example if SNP Production Horizon is mentioned as 21 days -  Therefore, up to 21 days (from system date) SNP will not plan production and only after SNP Production Horizon (21 days), SNP (or CTM) will create receipts. Planning within this time period (system date till SNP Production Horizon) is typically done by PPDS planning which plans for the short-term horizon.
PPDS Horizon is the time horizon during which PPDS can automatically delete, change or create orders. It is created in calendar days and counting starts from present date into future. (Deletion and change is possible only for unfirmed orders.)
PPDS Horizon is maintained in the ‘PP/DS’ tab of the product master in APO:
Also for overlap scenarios -
SNP Prod Horizon < PPDS Horizon: In this type of setup, PP/DS considers and takes care of SNP Planned Orders in the overlap period and plans accordingly.
SNP Prod Horizon = PPDS Horizon: SNP Planned Orders will be converted into PP/DS Planned Orders after they enter PPDS Horizon.
SNP Prod Horizon > PPDS Horizon: In this type of setup neither SNP nor PPDS will plan production. Though planner can manually create orders in this horizon also.
Hope it helps.
