MDS didn't appear in Demand Schedules in Plan Option after running the collection

Hello,

I need to specify the MDS in Demand Schedules in plan options (path: Advanced supply chain planner / supply chain plan/ options / organizations /Demand Schedules). However the MDS that we created doesn't appear in the LOV.

The setup we have done so far:

-  We created new  MDS (path: supply chain planner / MDS/ Names);

- MDS load/copy/merge ==> source type : specific Forecast , we choose forecast we want MDS to take copy of;

- We ran the collection and MDS collected ;

Is there any specific step that we are missing?
