For some reason, SAP newbies are under the impression that the process of generating developer access key on IDES is different from any other SAP NW system. It's not!
- Log on to the URL http://service.sap.com/sscr with your SAP S-user ID.
- Click on Register Developer.
- Enter the user name(s) and select the Installation for which the developer key is required, in this case it should be your IDES system's installation number.
- Click on Register.
- Copy the key and send it to the developer.
