How to change packaging UNITS?

If you have to change a packaging unit, e.g. from bag to big bag, you can proceed as follows:

if it is a stored lot (already posted via the warehouse journal), you can do it via a "REPACK ORDER" (for further details please go to How to do a REPACK ORDER?)
if the lot is not posted yet, you can just change the unit via Maritime Logistics - Inquiries - Warehouse lots

Select your lot and change to the "details view" in the bottom of the page, then change the unit and close the window.
