Specify a table name no longer than 30 characters

What causes this issue?

You wanted to copy table fields from the ABAP Dictionary onto a screen.
However, the table name you specified is longer than 30 characters.

System Response

Table names can be up to 30 characters long. The system interprets all
characters up to the first separator "-" as part of the table name.
Since the table name is longer than 30 characters, the system stopped
looking for the table.

How to fix this error?

Check the table name for errors.
