Foreign Key Dependencies

A foreign key dependency is a semantic dependency between two database tables, a foreign key table and a check table.

A foreign key dependency is defined in the foreign key table. Check tables are assigned to table fields and these fields become foreign keys.

Among other things, foreign key dependencies are evaluated for input checks, for input help on dynpros and in Web Dynpro, when creating views, and in lock objects. Foreign keys are not used in the ABAP programming language or in Open SQL.
