When importing a new project to Dash360, a specific import order needs to be followed. If you have imported a new system to Dash360, the import order is almost exactly the same. The order is as follows:
WBS Codes
Rates Files
Resource Files
Resource Results
Resource Calculations
Work Package Codes
Assign Codes to Project (Not an import)
Cost Estimates
Resource Assignments
This is the base requirement of data needed to create a functioning project in Dash360.
