Editing department names using HDL

Content

Hello all

My organisation wishes to update a large number of Department names. I'm hoping this can be done via HDL (Organization.dat?) but I'm not sure how this would work because in Manage Departments, I cannot see a unique identifier or unique code for each Department. Can anyone tell me how I could use HDL to do this i.e. if I enter the new department name in the file, how does Fusion know which existing department to update?

Does anyone have a sample HDL that I could use for this task? It's only the Dept name that needs to be updated, all other data will remain unchanged.
