To implement a referential integrity check, create a PL/SQL stored procedure which takes the table unique key(s) as its argument(s) and raises an exception if deleting the row would cause a referential integrity error. See: Integrity Checking LONG, LONG RAW and RAW Datatypes Avoid creating ta...
To do so, you define a function activity that makes a server-side call to the appropriate WF_DIRECTORY API and include that function activity in your process diagram. See: Standard API for PL/SQL Procedures Called by Function Activities and Workflow Directory Service APIs, Oracle Workflow API ...
