unable to do the pick release

 Hi,I need some help for meeting the client requirement

we are working for a wms -enabled organization

let me explain the requirement

based on item-size the item is classified into single-pick and multi-pick

if an order consists of 3 lines with one single-pick item with quantity 3 and tow lines of multi-pick items

i need the split the single-pick item in to  single quantity for the whole line quantity  and need to create the deliveries(3 deliveries for the line 3 i.e one delivery id with one quantity)

and for n multis in the order will comes in one delivery-id

up to this step we meet the client requirement  and after this based on wave number(custom sequence number popuated in delivery headers attribute columns)
