SNP and PPDs horizons

[Former Member]

Hi,

If I have SNP horizon of 0 days and PPDs horizon of 0 days. Then does the system plan twice and I see double the quantities because both SNP and PPDS are planning the same time? I mean does it create both SNP and PPDS planned orders doubling the planned qty.?

Thanks.

Typically if both these horizons are zero in the Location Product, the system is supposed to check the PPDS horizon kept in /n/sapapo/mvm transaction. Usually its a best practice to have a non-zero value in the version level. under the situation where even PPDS horizon at version level is 0, I would expect PPDS orders not be created at all by any systemic process. (different PPDS heuristics work differently though) However it should be possible to create PPDS orders manually outside of the PPDS horizon. Usually SNP orders are deleted and PPDS orders created in its place by the PPDS solver as soon as those orders are inside the PPDS horizon. I would be surprised by what you are observing though.

Hi Srinivas,

Thanks for the reply. I see SNP planned orders all over the place. We changed the SNP production horizon to 25 days and deleted the SNP orders and rerun the Heuristic. It now doesn't have any SNP orders in SNP horizon and only outside it.

The SNp and PPDS orders were not same qty. but the user says the SNP qty. is extra qty. he doesnot need.

We are running MRP with NEW shelflife w/ lot size profile, MRP with shelf life in PPDS.

technically it doesnt matter how the planned orders are created

the get considered by the planning run

if you have existing orders it will be either reused or considered into calculation

IMG--> in your heuristic profile, check what has been set up in the heuristics in the reuse mode

its possible that your snp orders are pegged and your ppds orders are working off shelflife

if you are runnig both PPDS and SNP you should look at note 481906 to understand the working of the horizons
