SNP Heuristic Run... How does it behave?

[sapfanatic.com]

I notice one thing in the behavior of Heuristic run. Assuming I put a huge safety stock, say 5,000,000 then system will automatically propose huge plans. Then I saved the results.

Later on, I changed the safety stock in my master data, I made it smaller, say 1,000,000
When I run heuristic again, nothing has changed, it seems that system didnot change any proposal because I still have lots of stock on hand and I do not have any shortage.

Is this how the heuristic behaves? wherein I still need to delete all the proposed plans given by the system for the 5,000,000 safety stock so I can get an updated plans for the 1,000,000 safety stock.

If that is the case, is there any other way that I can always have the heuristic run updated? Or is it really recommeded to delete the proposed plans before running heursitic again?

Hi,

The short answer is, the expected behavior of SNP Heuristics should be that when you change safety stock level in the product master, it should recognize this, and, when the Heuristics is re-run again, the proposed plans should change accordingly.

The only time that this WILL not happen is when some of your previously proposed orders fall outside of a given horizon (i.e. SNP horizon, stock transfer horizon, production horizon). SNP Heuristics deletes previous orders only if it is within the correct horizon. Once orders have shifted out of a certain horizon (also defined in the product master), your order will no longer be deleted by SNP Heuristics when it is re-run again. Another cause of this could also be that the order was touched/fixed in R/3 and therefore Heuristics does not touch this as well.

I suggest you have a look first at your horizon settings and ensure that all orders are deleted within the correct horizon.

Hi,

It is also worthwhile to check if the order was fixed. Generally, fixed orders are not touched by another SNP heuristic run. If your horizons are already correct, maybe this can solve your issue. Let me know if it does.
