Creating new departments using HDL

Summary:

Content (required):

Does anyone have some sample HDL that they would be willing to share with me to help with creating new Departments using HDL? I've tried using Spreadsheet Loader but keep getting errors that I cannot reconcile and also server errors! So I think HDL might be the better option

I want to create department records that contain the department name, start date, status as active, cost centre and cost centre manager name. Can all of that be done via one Organization.dat file? I've seen some other sample HDL but it didn't have the cost centre and contained other values like location and address that I don't really want to load that (unless it's required).
