Hi @Jim Dutton!
It's how you think. Reservations are created from materials planning in WO, and when you submit Material Requisitions (in "Self Service -> Desktop Requisition -> Create Requisition"). I would need to check if the PM forecast too (when you create forecasts in PM, it's can be easily tested in the system).
But in WOs, the planning stages are determined by the states, that is, while the WOs are in planning ("Waiting on") no reservations are created. They are created when the WO is approved or in execution (APPROVED, IN PROGRESS, etc.). Do the same test, but change the status in WO to one of these states and you will see the changes in the reserved quantities.
HARD, discounts the available amount and SOFT does not, it only informs the reservation and AUTOMATIC, it becomes HARD or SOFT depending on the date of need vs. the delivery time that is configured in ITEM. If you plan a material and set it that you need it between in 4 days, and the delivery time (appears like "Lead Time (Days)" in "Reorder Details" TAB in Inventory APP) for that material is 3 days, it will be HARD. If it is 5 days, it will be SOFT until tomorrow and it will be set to HARD.
I hope it helps you.
Regards!
