Journal Types determine the behavior of a Journal within Fynapse. They have to be properly assigned to Posting Components on the Accounting Rules Navigator, to ensure correct processing within the Accounting Engine. The following types of Journals are available in Fynapse: * Permanent * Reversing > **Info** > > Journal Types have to be configured prior to uploading any Business Events for processing in the Accounting Engine. ## Permanent Journals Permanent Journals are standard Journals that record a transaction and create DR and CR. ## Reversing Journals Reversing Journals are Journals that will be reversed on a specified date. Such a Journal consists of the original Journal posted on the Posting Date and its Reversal posted on a “reversing” date. The date on which a Reversal is posted can be configured individually per Journal Type. ### Reversing Journal Date Types The following types of reversing dates currently implemented in Fynapse: * Next day - in which the reversal is posted on the next day after the original journal * next day is calculated as Core Date of the original Journal +1 day * Next business day - in which the reversal is posted on the next business day after the original journal * business day is calculated based on the implemented Business Calendar * First day of next period - in which the reversal is posted on the first of the next period * first day of the next period is calculated based on the implemented Fiscal Calendar * First business day of next period - in which the reversal is posted on the first business day of the next period * business day is calculated based on the implemented Business Calendar * first business day of the period is calculated based on the implemented Fiscal Calendar * Last day of current period - in which the reversal is posted on the last day of the current period * last day of the current period is calculated based on the implemented Fiscal Calendar * Last business day of current period - in which the reversal is posted on the last business day of the current period * business day is calculated based on the implemented Business Calendar * last business day of the period is calculated based on the implemented Fiscal Calendar * Journal line field - in which you can select a field from Journal Line Definition to map as the Reversing Date Field > **Info** > > The [Business](/documentation/processing-configuration/calendars/business-calendars) and [Fiscal](/documentation/processing-configuration/calendars/fiscal-calendars) Calendars which allow Fynapse to calculate the reversing date are configured in the [Accounting Base](/documentation/processing-configuration/accounting-bases). The Accounting Base is assigned to the Posting Component based on which Journal entries are created. For more details, refer to **How to Configure a Reversing Journal for a Posting Component on the Accounting Rules Navigator screen?** ### Journal Types Screen To go to the **Journal Types** screen, go to **Accounting** **Configurations > Journals > Journal Types**. The **Journal Types** screen comprises a grid with existing Journal Types, which can be filtered using the filtering options in the grid columns. On the screen, you can also create a new Journal Type. To view the details of a Journal Type, left-click the Journal Type in the grid. A details section will open on the right-hand side of the grid. In the **Details** section, you can see the Code, Description, and Type of the Journal. The **Journal Type** screen also has the **Refresh** button, available above the grid. It allows you to refresh the data on the screen and see if other users added a new Journal Type. > **Warning** > > It is not possible to edit existing Journal Types. > **Info** > > Information about whether a Journal is reversing appears on the Journals Subledger screen. If a Journal Line is “reversing“, the **Reverses** column is populated with the Journal Line ID of a Journal Line being reversed. ## Tutorials #### How to Create a Journal Type? 1.

For more details on editing and cloning Posting Components, refer to [Working with the Accounting Rules](/documentation/accounting-engine/working-with-the-accounting-rules). > **Info** > > Once a Posting Component with a Reversing Journal Type is created, it has to be incorporated into the Accounting Rules of the Accounting Engine by mapping it with a Business Event Type and creating a Posting Pattern for linking it with an Account Lookup Posting Code. > For more details on how to incorporate a Posting Component into Accounting Rules, go to [Working with the Accounting Rules](/documentation/accounting-engine/working-with-the-accounting-rules).
