Hi Gift, There is currently no UI screen in Bahmni for adding/editing/delete wards or beds. The implementer has to do it using SQL queries. Please refer the wiki page here : https://bahmni.atlassian.net/wiki/display/BAH/Ward+Management
There are some other talk threads also that talk about ward management like this one : is there any module that can manage Bed in hospital instead of adding script simple UI Referring them might also be helpful.
