To access the configuration of the module, select Stores->Configuration from within the admin panel...
Now scroll down to the 'On Tap Modules' option, and select 'Park Order'...
You will then see the module's configuration page...
These options are as follows:
|Enable cleaning of parked orders|
If this is set to 'Yes', then a scheduled task executes daily in order to minimise the number of old parked orders on the system. This is to stop the database getting too large. The criteria for 'old parked orders' is determined by the following setting. Any such parked orders are removed from the database automatically.
The scheduled task runs at 00:00:00 each day.
|Number of days to keep parked orders|
This is the number of days you wish to keep parked orders in Magento for. The default is '5'. However, you can change this to any number that suits your needs.
This setting is only considered if 'Enable cleaning of parked orders' is set to 'Yes'.
You can limit access to prevent users from accessing Park Order option. In System->Permissions->User Roles...
... when editing or creating a role, make sure 'Resource Access' is set to 'Custom'...
Then in the 'Sales', section, there is an option called 'Parked Order, Retrieve Parked Orders and Delete Parked Orders'...
... if this is un-selected (as in the example above), then any users who have this role defined will not be able to access Admin > Sales > Order > Park Order and Retrieve Park Order functionality. If you require assistance in setting up roles, please refer to the Magento documentation about this.
