In the Key definition working area, selecting a value for the Reference Key table column is not required if the current key is a not a foreign key. When the current key is a foreign key, the following two situations are possible:

  • The value in the Reference Key data column is the same as the one specified under Key Name; in this case the Reference Key data column is left empty, as in the following example:

    If using the CABLE_MOD_ID from the CABLE table in the key definition, the key name CABLE_ID is identical to the reference key.

  • The value in the Reference Key data column is different from the one specified under Key Name; in this case the appropriate value appears under the Reference Key data column, and the column title Reference Key is displayed in bold text, as in the following example:

    If using the CONNECTOR_SIDE1_ID from the CABLE table in the key definition, the key name CABLE_ID is different from the reference key, the value of which in this case is CONNECTOR_ID.
