Zugangsschluessel - access key

Hello,

I am currently trying my first ABAP programmer steps in IDES.

Unfortunately I am not getting to the acctual entry mask.

After having typed "SE38" into the command field, having named the programm

selected Attributes and then clicked on Create. I receive an error mssage that reads as follows:

"You are not registered as a developer. Please register in the R/3 Online Service System (OSS). You will receive an access key upon registration."

Can anybody tell me where I can get this access key or onto which site I have to log on to to generate it?

Sorry if the translation is insufficent as I work from the German system.

Thanks very much for your help,

Claudia Erb
