HI Syed,
we want to transfer or ship the item from one subinventory to another subinventory those two subinventories should contain the relation other wise we need to create the sourcing rule and then only we can transfer the item.
Sourcing rule is defined for mainly for use in Planning.
You can define "Buy from" "Make At " and "Transfer from" in Rule. As per rank and allocation % Planning sugestion will be relleased from Planner Work bench
