Hi there again,
since you helped me through this once, I got a lot of additional know how. But the best is that I now know for sure that there is in fact an upgrade toolkit from 3.xx blue to 2.60 Financials. It consists of a report for the blue version and a couple of reports and codeunits for Financials. Meanwhile I also found a manual which describes this package in nearly 500 pages. So I am looking for this toolkit, but I cannot find it anywhere.
Does anybody have this kit? German version is preferred but any other is accepted as well. Thanks for your help!
