Hi,
In this case, as Agustin said you need to add both the Depreciation areas that are mentioned in the asset class. Also If you are not getting the quantity and APC then just keep the sequence proper as first Item No, Description, asset class, asset group, depreciation type, useful life, APC and then Quantity. You will be able to do.
Also what you can do for opening is that try doing capitalization using the ofset account. This will also help.
regards.
