If tableField = "Process ID" and layerField = "PID" then this works:

IRelationshipClass relationshipClass =
    table as IObjectClass,
    geoFeatureLayer.DisplayFeatureClass as IObjectClass,
    esriRelCardinality.esriRelCardinalityOneToOne );

If tableField = "Process ID, Year Made" and layerField = "PID, YM" then it fails.

(Table is SQL Server table.)

I have tried brackets and quotes to no effect. Is it possible to pass a compound key?
