The functionality of Bin's as on Sales, Purchase and Whse/Inventory documents and journals doesn't seem to work very well in Job Journals (NAV2009 SP1).
After adding the field 'Bin Code' to the Job Journal Page/Form all the Bins appear (not only the bins where stock are available to pick from) when you try to select the Bin from which you are taking items for a job.
You can then also post the Job Journal even if the bin doesn't contain any of the item.
Is this a:
1. Bug; or
2. The way the system works; or
3. A user(setup) problem?
