No column View after activate attribute view
I am using hana trial system, after save and activate attribute view , no column view is creating under _sys_bic for location attribute view, while earlier 4 column view created upon activation of attribute view by us.
1. Save & activate attribute view.
2. Attribute view is activated.
3. Refresh _sys_bic schema .
4. No Column view for Location Attribute view.
What can be reason for it?
