MRP Rescheduling Horizon equivalent in APO-SNP?

Hi all,

In (ECC) MRP we currently use the Rescheduling Horizon to limit creation of purchase requisitions when an actual Purchase Order already exists (but is outside the standard lead time).

e.g. Lead Time = 7 days. Rescheduling Horizon = 50 days

If requirement to reorder exists in 5 days time, and we have actual PO due in 14 days time that can cover it, then no new PurReq is created.

We're now moving to APO-SNP to generate our purchase requisitions.

Is there an equivalent field in APO-SNP we can use to accomplish the same result?

Many thanks,

    Hi Gerg

    Can you check SNP Stock Transfer Horizon field in the APO master data in SNP2 tab in T-code /SAPAPO/MAT1.

    Use in SNP:-

    Enter the number of days, weeks, or months during which the system is not to plan stock transfers. The time period starts on the system date (or if required, the date specified in the Planning Start Date field of the planning book or in the PDATE user exit for background processing). The system does not generate any planned distribution receipts within this horizon; instead, it moves them to the first day after the SNP stock transfer horizon

    Please request you to check the topic and let´s know if it helps.

    • No, there is nothing like that for SNP. PPDS has options but SNP does not.

      Using time buckets you can "aggregate" supply into a particular time bucket so any orders in the same time bucket are considered available in beginning of time bucket but I think that is a bad idea.

      CTM can peg to existing supply first before creating new supply elements.

      Optimizer you can set delay costs so small that it will utilize existing supply before procuring additional supply.

      But these are only workarounds.
