The tool does not support object type : JOBS .
The job belongs to the selected schema and the " schema compare / Source Control " ignores this type of object.
Scott Kellogg commented
Add the ability to compare / snapshot Oracle chains, programs, and scheduler / DBMS jobs owned by the schema. They can reference a PLSQL block in the chain too. A chain that references a stored procedure will have the target in there already under the "Procedures" section.
