You selected the matchcode sub-keys function for a field for which nomatchcode sub-keys can be defined.

System Response
Matchcode sub-keys can only be defined for fields to which a matchcodeobject is assigned and which also have the following attributes:

• - input/output field

- not a graphical element (e.g. checkbox or pushbutton)
- no assigned icon
Since at least one of these conditions is not satisfied, the systemdoes not execute the function.
