WMS: Usage of Generate LPN

Hi,

Can anybody tell me the usage of Generate LPN in WMS. As the user guide does not give much information on the usage.

What I trying to achieve the following

1) Create PO.

2) Perform Expected Receive via FORM and not thru Mobile Device

3) Run program Generate LPN to create LPN

4) Print LPN labels. Stick to item before Put-away using Mobile Device

Please can you advice if step 2 and Step 3 is possible

Steve
