Master planning has many coverage types, min/max is only one of them and may not fit to every company requierement, so I think it would be better as AdamRoue says to take a look at the planning manual to know about the whole functionality. Anyway I will give some steps to make the setup based on min/max for produced, transferred and purchased items.
You may already have the coverage group for min/max created.
Attach the min/max coverage group to items, in this example I have two items 0001 (type item) and AGR-1004 (produced) with that coverage group.

As you can see, for item 0001 I have two min/max definitions one for whse ‘Fabrica’ and the other for whse ‘Fert’. The particular thing with this two warehouses is that whse Fert was setted up to be fullfilled from whse ‘Fabrica’ in the whse parameters
Now this is the coverage for produced item AGR-1004

So what would we expect from master planning considering there is zero stock for all of them?
After running Master scheduling you will see
The upper pane shows the 2000 units required by the max qty of the min/max coverage line. The mid pane shows it is a planned transfer order, becouse this whse FERT is setted up to be supplied from FABRICA (stated in the From wharehouse field). The lower pane Pegging says where the requirement comes from, it is for Safety stock, 200 units which is the minimum, so as everything here is a proposal you can consider to decrease the quantity, but if you do so, as your min/max parameters remains the same if you decide to decrese the qty from 2000 to 1000, a new running of master scheduling will request you 1000 units to cover the max qty.
The upper pane shows the 3000 units required at Fabrica (1000 max qty at Fabrica+2000 transfer order). The mid pane shows it is a planned purchase order. The lower pane Pegging says where the requirement comes from, it is for Safety stock, 100 units which is the minimum that you don’t have at whse Fabrica, plus 2000 units for the transfer order.
The upper pane shows the 10000 units required at Fabrica (max qty at Fabrica). The mid pane shows it is a planned work order as it is a BOM item. The lower pane Pegging says where the requirement comes from, it is for Safety stock, 2000 units which is the minimum that you don’t have at whse Fabrica.
Hope this is what you need. Best regards
