However, you may choose to have a prefix next to the transaction number to easily and quickly identify the type of transaction that has been created. As an example, you may want *IN* to identify your invoices, or *CR* to identify your credits. The following document explains how to add these prefixes. #### Select your transaction screen From any screen in Paragon, click the **settings** button at the top right corner of the screen. ![](https://support.paragon-erp.com/hubfs/Knowledge%20Base%20Import/DocsDisplay-Feb-02-2024-09-37-23-6673-PM-1-1-3-1.png) Select the **screen setup** option from the **system** card. ![](https://support.paragon-erp.com/hs-fs/hubfs/Screen%20Setup-jpg-1.jpeg?width=688&height=320&name=Screen%20Setup-jpg-1.jpeg) Select your transaction screen from those listed below screen setup. In this example we are using the **invoice** setup screen. The same steps can be followed for all transaction screens in the screen setup module. ![](https://support.paragon-erp.com/hubfs/Knowledge%20Base%20Import/DocsDisplay-Feb-02-2024-09-37-22-7634-PM-1-1-3-1.png) #### Edit the transaction screen At the top right corner of the screen, click the **edit** button. ![](https://support.paragon-erp.com/hubfs/Knowledge%20Base%20Import/DocsDisplay-Feb-02-2024-09-37-21-8636-PM-1-1-3-1.png) You will have the option to create, modify or delete a prefix. Type in the prefix of your choice. ![](https://support.paragon-erp.com/hubfs/Knowledge%20Base%20Import/DocsDisplay-Feb-02-2024-09-37-25-8306-PM-1-1-3-1.png) #### Save the changes you made Save any edits you made by clicking the **save** button at the bottom right corner. ![](https://support.paragon-erp.com/hubfs/Knowledge%20Base%20Import/DocsDisplay-Feb-02-2024-09-37-26-4165-PM-1-1-3-1.png) Once you click save, the following notification will appear prompting you to log out and back into Paragon to complete the change. ![](https://support.paragon-erp.com/hs-fs/hubfs/Screenshot%202025-05-22%20090851-png.png?width=304&height=92&name=Screenshot%202025-05-22%20090851-png.png) #### Log out and back into Paragon Click the **log out** button at the top right corner of the screen. ![](https://support.paragon-erp.com/hubfs/Knowledge%20Base%20Import/DocsDisplay-Feb-02-2024-09-37-21-0175-PM-1-1-3-1.png) You will be taken back to the login page, where you can enter your credentials to log back in. ![](https://support.paragon-erp.com/hs-fs/hubfs/Paragon%20Login%20Screen-png.png?width=688&height=333&name=Paragon%20Login%20Screen-png.png) #### What's next?
