Definition

If an input/output field is assigned to a matchcode object and the user makes a matchcode selection, field values from the selected matchcode record are placed in the appropriate fields of the current screen.

The relationship between matchcode fields and screen fields, i.e. which screen field is supplied with values by which field of the selected matchcode record, is determined here by the field ID.
This field ID is assigned when the matchcode object is defined in the Dictionary. Each matchcode object field which has a field ID can give its value to the current screen.
The field ID 'KEY' is predefined. It is used to pass the value to the screen field where the matchcode selection is triggered.

If you want to supply other screen fields with values from the selected matchcode record apart from the field used to trigger the matchcode selection (i.e. the key field), you must define sub-keys for this field.
A sub-key belongs to the key field and consists of the field ID and sub-key field name). The field ID corresponds to the field ID of a matchcode object field. The sub-key field name is the name of an input/ output field on the screen.

When a matchcode record is selected, the system checks, for each field of the record which has a field ID, whether there is a sub-key with this field ID for the key field of the current screen. If so, the value of the matchcode field is placed in the screen field whose name is specified as the sub-key field name in the sub-key.
