Good morning Shaun,
I think that you can import things - either with data management or electronic reporting (ER).
Have, however, not found a standard entity in the data management workspace, which means that you need to use either ER or create a new entity for the import.
The other thing I am wondering is the thing with the allocation across periods.
That is something that I don't understand.
Why would that be needed?
I am asking because the WBS contains the start and end dates, which define the dates for the budget.
What is it that needs to be reallocated across periods?
Best regards,
Ludwig
