Diagnosis
You adopted an ABAP Dictionary element as a checkbox or radio buttonwith text into a table control, and a naming conflict with an existingscreen element resulted.
Within the table control, the text of the checkbox or radio buttonforms the column header, and the input/output field forms the columnelement. Since the names of heading and column elements must bedifferent, the name of the header element is changed to a star ("*").This is the cause of the problem.

System Response
The system only copies the input/output field from the ABAP Dictionary.It does not create the header element.

Procedure
Rename the text element that was causing the naming conflict, then copythe heading text for the table control column again.
