Procurement Scheduling Agreements in Heuristic-Based SNP

[Former Member]

Hi,

I have a question about Procurement Scheduling Agreements in Heuristic-Based SNP. I was reading through

<a href="http://help.sap.com/saphelp_scm40/helpdata/en/d6/07783b12fc9f20e10000000a11402f/frameset.htm">this topic</a> in help.sap.com

The last paragraph: "If the confirmation quantity is less than ....... as described in step ", says that the first Heuristic run is executed, then plan is sent to supplier and he either changes or confirms the supply qty Then if the qty. from the Heuristics result is more than what he can supply, the Heuristics run is rerun <u>"taking supplier capacity into consideration"</u>.

As far as I understand Heuristics, it is a qty. based rapid cross plat planning that do not take capacities into consideration. But here it's saying that the Heuristics is rerun taking capacities into consideration. That confuses me! Can somebody please explain this to me? What difference in the second run makes the Heuristics take capacity into consideration?

Thank you.

Hi Visu

SNP heuritics based planning involves heuristics(infinite) and heuristic based capacity levelling (with constraints) together.

the first run and second run are run with different settings. the first infinite and the second with the capacty constraint.

in the help page you refer to pl see point 2

also see point 8 on http://help.sap.com/saphelp_scm40/helpdata/en/4a/563a18305211d3b6270000e82de178/content.htm -

you can set up capacity constraints and still run heuristics (the real meaning of heuristics being a set of rules)

the terms being used sure make it confusing
