SNP Optimizer planning

Dear All,

I got an problem during SNP optimizer run in production.

Scenario : We have got no demand for for FERT but after SNP optimizer run it is getting planned...It is not showing any demand in consensus plan od Demand Planning and also no any demand lies in SNP planning book.. Although it is having past dated damend which in past.

In Data view of SNP planning we are not considering the planninf bucket in past.. Every thing is getting planned for future only..

Can anybody suggest me the reason why SNP planned orders are getting generated..

This is urgent please help.. POints will be rewarded for the same
