Hi Andreas,
There is no function to export data from Adagio SalesAnalysis and make external changes, nor is there a function to import data.
You can use the Change Selected Sales Data utility to change a category code from one to another. There is no requirement to maintain a link to item number - otherwise it would be invalid to change the category code at all (even with Excel and importing). Use this function to make a change such as 'all category codes ABC will be changed to XYZ'.
