Partial pick release or fixed qunatity pick release when WMS is enabled

 Hi All,

I have case where the total stock of ITEMA = 50 and the sales order created for the ITEM A = 100. The requirement is to run the pick release and the 50 qunatity i.e. in stock  gets allocated and rest of the sales order quantity should get back-ordered or remain as its for the next pick release when stocks comes in.

Conditions : The organization is WMS enabled

Secondly, we don't want to go with the option where the quantity should be reserved first and then pick release get fired with the option of "Prior reservations only".

Thanks
