Enter a table name

What causes this issue?

You are trying to add a new entry to a BC Set. The cursor was not
positioned on any of the table entries listed, so the system requests
the name of the table from which a record is to be added to the BC Set.
You continued without entering the table name.

System Response

The system cannot continue if you do not specify a table name.

How to fix this error?

Enter the table name now, or cancel and then position the cursor on the
name of the table from which a record is to be added to the BC Set.

Procedure for System Administrators
