Unpickable or Quarentine location types would typically be used as a temporary holding location until stock has been properly checked, inspected or counted in either goods in or returns processes.
When you book stock into an unpickable location on Mintsoft it will increase "offhand" stock level - this does not get included in any stock syncs sent to externally connected sales channels with inventory sync enabled.
Then when the stock has been checked properly you can easily transfer it out of the location to a good location using the scanner or browser transfer process.
If the stock is not good enough to be picked then you can instead book the stock out off the unpickable location completely.
Add Unpickable Location Type
Go to Warehouse > Extras > Location Types
Then add a new location type and toggle on Unpickable:
Add Locations to Unpickable Location Type
Next you need to add locations to the unpickable type - you can either create new locations or move existing locations to the new type.
If you move existing Location IDS to an unpickable type - please check there is no existing stock that needs to be picked.
Ideally the locations should be clean from stock before moving to unpickable.
Go to Warehouse > Manage Warehouses > Locations
Then either select the green option in top right to Add New Location or edit an existing locations by clicking Actions > Edit and then making sure to select the unpickable location type:
