Validating CRCs for Schema Triggers
When a database event occurs in your application (such as creating a record or assigning a field), Progress checks whether the CRC of the corresponding trigger procedure matches the CRC in the trigger metaschema record. If it matches, Progress executes the procedure. Otherwise, Progress returns a run-time error.
Trigger CRC validation works for both r-code and source versions of a trigger procedure. For source versions, Progress calculates the CRC during the session compile.
