You wants to see multiple jobs for the same employee,but you noticed Source diagram created unexpected join when data elements are joined with the same column (JOB_ID).
Steps to reproduce:
1. You connect to sample tables of HR schema.
2. Match EMPLOYEES and JOB_HISTORY by JOB_ID. Then match JOB_HISTORY and JOBS by same column JOB_ID.
3. In Data Elements, right click on EMPLOYEES-> source diagram, notice that EMPLOYEES, JOB_HISTORY and JOBS tables get mutual match although you didn't match join between EMPLOYEES and JOBS.
4. When you delete the join between "EMPLOYEES.JOB_ID" and "JOB_HISTORY.JOB_ID", then other 2 joins would loose unexpectedly.
