You have created several account groups with the Display in option as Expenses. Which setting determines the account group that will be displayed in…

When multiple account groups are created with the same "Display in" option (e.g., Expenses, Revenues, Assets), you must specify which one should appear by default on the General Accounting infolets on the home page. The "Set as Default" option designates a specific account group as the primary one to be displayed for that category. While users can typically cycle through other available account groups on the infolet itself, the default setting determines the initial view. Access levels like Public or Shared (C, D) control visibility to other users, not the default display for an individual.

Oracle Fusion Cloud Financials, Using General Accounting, Release 13, F48153-02, Chapter 3, "General Accounting Dashboard". In the section "Account Monitor," it describes the process of creating account groups and states: "Select the Set as Default option to display this account group by default in the infolet." This confirms that the "Set as Default" setting controls which account group is initially displayed on the home page infolet for a given category.
