Hi Andre
For the benefit of others (I emailed you this already)...
The solution to creating your report starts with using GridView to create a two column Excel spreadsheet - column A is the customer number and column B is the On Order Amount for that customer. Once the Excel spreadsheet is created, highlight the two columns and use the Define Name function of Excel to give the two columns a Name. Let's call this a named range. Save the spreadsheet.
Now use Crystal Reports to create a basic sales report using data from SalesAnalysis. Crystal Reports for Adagio can link to the named range in your Excel spreadsheet to get the On Order Amount and include it on the sales report. Voila!
This is the concept. There is a lot more to the implementation, that's why I have a job. But you get the idea.
