If the user is trying to manually raise and produce a credit in Workshop > Invoicing > Raise Credit, the user will need to enter in an invoice reference number within the 'Reference' field as shown below:
However sometimes this Reference field will not be visible for the user to type into. The reason for this is because there is a separate access level required for this field to be visible.
In order to set the access level limit for a user to be able to have access to the Invoice Reference box, go to Workshop > Parameters > Parameters > Access Levels. As highlighted below the department requires a workshop access level of 80 or above to be able to have a visible Invoice Reference Box.
This access level can be altered higher, or lower via this screen. Alternatively, the individual user's access level can be amended to a Workshop access level of 80 or above within Administration > User Admin - Users Tab.
