Consolidated Picking till ship load
This is a new issue, but I am posting it here just for you to understand the requirement.
Solution provided by you is working (multiple lines of a customer order can be picked using single OBLPN). We are planning to create a Wave Template in which we would generate task based on Item code lets consider it as Item A.
This wave template should group Quantities of all the orders having the item A and generate is single pick for them. For example if there are 10 order lines against different customer having item A of Qty 10. So when wave is ran it should generate single pick for 100 Qty.
