Item help

Hi I am new here and I need help for my new map.
I hope one of you could help me.
I want that when my inventory is full, and if I try to get one new item, other items in my inventory get remove on the field and the item I wan't to take get remove on my inventory.
For exemple one units find a clow of attack but he can't take it cause his inventory is full. Instead of saying "inventory full" i would like that the item he has in his inventory get remplaced by the clow.
sorry I am not English I hope you understand me

Where are you from?

I don't belive this is possible.

A way which may work proper:
You'll have to detect a unit drop item event.
Then you should remove a random or maybe the weakest item from the unit inventory and add drop the other in this slot.

But:
If all itemslots are used it won't work.
Think on that.

It sounds a bit strange, I know.
