Before Importing Data to ShipWeight make sure your data is ready for import.
The data need to be a continuous list of data without blank lines or rows, the data file import stops when encountering a completely blank row and assume that the import is finished.
The Import file should have a weight group column or a column that can be mapped to weight groups, if the weights are to be imported to a weight group and not the Temp folder, and the data that you would like to import. E.g. Weight and CoG and the Code information you would like to include.
