Application Source Qualifier <Application Source Qualifier name> has Effective Date Extract Join Order with invalid number of source names. This should be equal to the number of effective dated records in the DSQ.
In the Effective Date Join Order field, you entered too few or too many PeopleSoft record names.
Edit the Effective Date Join Order field so the number of records you enter equals the number of records associated with the Application Source Qualifier. Verify that you separated each PeopleSoft record name with a comma.
