Currently accoMasterData does not support Hierachies - atleast in a visual context. Would be great to display row values in a traditional hierarchy. With the option to expand/collapse.
Row Creation:
Most often than not, masterdata is related to other dimensions in a hierachy setting. Example Organisation -> Employee.
Currently, when creating a new Employee the employee has no relationship to the organization and the organisation must be manually entered into a measure.
Idea for improvement is to enable row-creation directly within the context of the hierarchy. The idea is, if you highlight the organisation department "Sales" and click on create row (new employee), the row will be created within the Sales department.
In turn, this feature could be combined with a transaction key to correctly assign the organisationKey to the newly created row.
