¿Qué causa este problema?

You did not define a target field. In order to be able to use matchcodes
as an online utility, you must set up a connection between a matchcode
field and a screen field. This connection is defined with the target
field. In a matchcode selection, the value of this field is transferred
to the screen field.
The first key field of the primary table is standardly defined as the
target field. You probably deleted this assignment.
