    Dear Ladislav,
    what ist the action about “How to prolong SAP Trial license?” for my version SAP NW AS 7.50 SP2?
    Best Regards

    • Hey Atilla.
      THe license mentioned on this page is not related to the one which SAP stopped supporting.
      This license correlates to having access to log in to the system.
      The ASE license which expired March 31st relates to the database which goes along with the SAP system. Since SAP is not able to extend the license for that database in the way they usually did, they needed to stop supporting this system.
      In the newest system 7.52 the ASE license will be valid for 1 year so later we all will deal with the same.

    • Well, we are not sure how to update licensing for different systems. We are using all legal options provided by SAP and this is the standard way on how to update license.

    Best function.


    Hi! I followed the steps but it didn’t work out. Keep showing me the message “login not possible (error in license check)”.

    When you enter the new registration key, in the status field, no balls appear neither red nor green, they are all colorless.
