Sometimes we have created a custom checkbox field and checked the “Default Checked” field in the custom field page and applied in the desired record, so that the field will be checked by default when a new record will be opened. But the checkbox is not checked. Have you faced such situation? If yes, here is the solution.
Solution:
Go to the Customize Form of that record where that checkbox should be shown.
In the Screen fields tab, search that field. When found, check the checkbox in the column “Default Checked” for that checkbox as shown below.
Then save the customize form. Now when you create a new record, that checkbox will be checked by default.
But for existing record (which means the records you have created earlier), checkbox will not checked by default.
Hope this helps you.
