Nah, come on, that can not be difficult! 
What did I wrote?
"In the ROD / AFS scenario the change from one storage location to the other is triggered by the mandatory requirement of the stock to be in a certain availability group in the final storage bin (the field availability group and the flag "mandatory" in the storage type)."
So all you do is NOT to enter any availability group in the storage type and NOT to flag the field "Mandatory".
