Also Checked in SPRO-> Cross Application-> Classification System-> Classes-> Maintain Object Types & Class Types.
When we select MCHA from the Tables on the right side and then Click on Class Types folder on the Left hand side, we can view the Class Type : 023 assigned to Batch on our right side. There we hav some checkboxes below it. One of the check-box states "Multiple Classification", that checkbox is not selected.
When we check the same in the Older Version 4.6, there also the check-box states "Multiple Classification", that check-box is not selected.
