External data groups which come from the Intrexx standard connection can also reference any standard data groups. When integrating external data tables, incorporating
  • multiple primary keys
  • multiple foreign keys
  • mixed primary and foreign keys
is not possible. Certain conditions apply to references to external data groups: If the external data group originates in the Intrexx system database - the standard connection SysDB -, creating references is usually possible but only if the external data group is a physical data group. If the external data group does not relate to the Intrexx system database, then the reference is not possible.
