If you've given one of your tables the wrong name by mistake, you can rename the table at any time.
To change the name of a table:
Access the table properties in one of the following ways:
In the table bar on any application page, click the table you want to change. Within the menu that appears, select Customize --tablename-- table > Properties.
In the menu bar on any application page, select Customize > Tables. Within the list on the left side of the page, click the table you want to change and click the Properties tab.
In the Table name text box, enter a new name, and then click Save & Done.
NOTE: This operation changes the term for table everywhere in your application, but it doesn't change the label that displays on your application's table bar. You must change this manually. Read how. But, changing the term for records in a table DOES change the label in the table bar.
