Hi @Kmullervy, We tried using the native Demand planning that NS provided. I spent a good 10 months researching it all and getting everything ready to push it forward. in the end we weren't able to use it because we place our purchase orders to in transit warehouses instead of the main warehouse, and the native demand planning wont allow you to have a demand plans order to a separate warehouse. There were a couple work-a-rounds that we could do but they would end up messing with the accuracy of the demand plans over time. NS knows about this problem and have it classified as an enhancement with no planned fix date. So we put demand planning on hold for the time being. For that reason and because the third party Demand Planning programs that support netsuite cost quite the pretty penny.
But if you don't order to a separate warehouse then you may be fine.
