Imagine that you create an application and tested it out by entering a few sample records. When you feel that the application is ready, you'll want to start entering live data. Before you can do so, you need to get rid of your sample data. There's no need to delete each individual record. You can delete all records at once. To do so, follow the steps below.
Caution: Once a record is deleted, you cannot retrieve the data it contained.
Note: The word "record" refers to the records in a table, but the term you use in your application may be different (for example, "contact," "task," or "issue"). This means that the text in the instructions below may be slightly different from what you see.
To delete all records in an application:
Open the application from which you want to delete all the records.
From the app home page, click Settings, then click App management.
Click Delete data.
If your application has multiple tables, select the table whose data you want to delete.
Click Yes, delete all records to confirm the action.
(Depending upon what you call records in your application, this button may say something like Yes, delete all Tasks or Yes, delete all Contacts.)
To delete data from more than one table, repeat steps 2 to 5 for each table.
