Workaround for Manual Reservation in Supply Planning

Hi Team,

We identified that Planning doesn't collect manual/user defined reservations. We have requirement to have such user defined reservations for onhand because of possible demand in future and want supply plan to respect that.

I have got two suggestions for it but both are not possible for our scenario

1. Use not-nettable subinventory for storing such goods- This will remove the visibility of such goods altogether in the plan itself. We do want to see it in plan.
2. Use Simulation Set- We can create Manual Demand in Supplies and Demands but here we will not be able it to link the exact supply with the demand.
