**Marlin GTX** enables users to add, edit or delete suburb and postcode entries wherever customer information can be edited.

Suburbs and postcodes can also be managed using the Postcodes Maintenance module.

Customer Maintenance

Suburbs and postcodes can be added and edited wherever customer information can be edited (e.g. Work Orders, Invoices, Customer Maintenance).

Click the Magnifying Glass in either the Suburb or Postcode field.

To add a new entry:

  • Press the Insert key on the keyboard
  • The Create Postcode pop-up will open:
  • Enter the required details
  • Click Save

You can also edit existing suburb information by selecting it and pressing Ctrl+E on the keyboard.

Suburbs and Postcodes can be deleted by selecting them and pressing the Delete button.

Note

Regardless of whether the suburb is entered via the Suburb or Postcode field, both will be created when the Save button is clicked.

Postcode Maintenance

Suburb and postcode information can also be added and edited, independent of customers, using the Postcode Maintenance module.

To access the module:

The Postcodes Maintenance module will open, showing a list of active suburbs and postcodes within your GTX system.
