Lot Size and Safety Stock planning in IBP Supply

Hi,

I am trying to model simple lot size (static/dynamic) and simple safety stock (safety days/safety stock) in IBP supply.

I have added the key figure - SUBPERIODSOFSUPPLY and COVERAGE into the planning area.

Also added the attribute "lotsizepolicy" in the location product.

Heuristic is not considering any lot size policy (neither 1 nor 2).

Also added attributes - safety days ind, safetydayssupply and safetystock.

But Heuristic not considering any safety stock input, neither safetydays nor safetystock.

Anybody who has been successful in modeling these parameters in IBP supply? Appreciate any help in this.

Thanks.
