Container Journals should generally only be used when there is a need to convert an existing Bin into a Container Tracked Bin so you can move container tracked stock into them.  In addition, they can also be used to make any corrections to Container Entries and Contents where required. 

In order to be able to use this functionality, you will need to ensure that a Container Journal Template and one or more Container Journal Batches have been created.

NOTE - When Container Journals are posted, they will only create Container Entries and Contents and will not create any Warehouse Entries or Item Ledger Entries etc.
