SAP EP 7.0 Enterprise Portal License Key

Dear Experts,

i have installed a SAP EP 7.0 Enterprise Portal and i would like to get a permanent Licence Key.

In the SAP Portal Service MarketPlace, il went to Keys & Requests -> Licence Key -> Request License Key

System Type: Demo System

Product: SAP Netweaver

Product Version: SAP Netweaver 7.0 (2004s)

Database: Microsoft SQL Server

Operating System: NT/Intel

Everything seems ok because the text file shows EXPIRATION=99991231

In the Visual Administrator, -> Licensing Adapter, i installed the license from the file.

and when i check my expiration day, i have j2ee-engine_MSS : 6 days remaining

Did i make something wrong? or is there another way to make it well?

Thank you very much in advance.

Best regards.

Pascal.
