SNP Planned Orders creation

[Former Member]

Hello all,

We are in SCM 4.0. In our scenario, we run PPDS Heuristics at the FERT level and it creates Dependent demand at the Component and based on that SNP heuristics run at the Component level.

If we maintain a PPDS Planning Time fence as 120 days, and SNP Production horizon as 120 days, our requirement is, when the user keyin some value within the Planning time fence, it creates a dependent demand within the SNP Production horizon at the Component level. When SNP heuristics is performed, SNP Planned orders should generate within that horizon. Is there any way to make this happen?

Thanks,

Sai

if you want the dependent demand to be at the same time as the primary demand without taking into account the lead time or ppds horizon then its not dependant demand anymore

So you can just create a direct relationship between a virtual FG and the component and have the real FG as a component and run the heuristics

for eg if you now have A -- Fg and B and C as Components

make a new bom with Z - Fg and A B and C as components

you can have the snp horizon of Z set to 0 and that will push dependent demand to the components where you want it to

You may have to write a custom program for what you are asking. The functionality that you ask though does exist in PPDS (goto PP/DS tab and set the PP Planning Procedure to 3 - not sure if this is at component or header - but check this one out before embarking on the complex development path).

If you are insisting on SNP, one thing you could possibly think of doing would be to schedule SNP Heuristics in delta mode very frequently (once every 30 min so that new demands are picked up). In transaction /SAPAPO/SNP01 use the Net Change Planning option since you would not want too much time to be consumed everytime when Heuristics runs.

If you want SNP Heuristics to run immediately, then you would probably want to write a user exit macro that senses an unplanned dependent demand and scheduled heuristics in background using SE38 report /SAPAPO/RSNPDRP1.

Srinivas, thanks for the reply. Let me try these options and come back to you

when we try to run snp heuristics immediately after the generation of dependent demand, the system is planning outside the snp prod. horizon but we are looking to plan inside the horizon
