Who should request license keys?
License keys should be requested by the SAP partner. Prerequisite for requesting a license key is a S-user and the authorization for the partner "License key request for SAP partner" for the corresponding installation number. Only in exceptional cases if an end-customer should not have an SAP partner the license key can be requested by the customer itself. For further information, see SAP Notes 124703 and 103926.
What should I do if I have mistakenly requested a license key for a new system instead of a license key for an existing system?
Delete the systems that were requested repeatedly as described in SAP Note 614911. Afterwards you can request the new license key for the existing system using SAP Service Marketplace from service.sap.com/licensekey, choose SAP Solutions for SMB , choose request license key. You can find more information on requesting a license key in SAP Note 578256.
What should I do if I requested a license key using an incorrect installation number?
The system ordered using the incorrect installation number should be deleted and re-requested using the correct installation number on the SAP Service Marketplace. The deletion process is described in SAP Note 614911.
How do I receive the license key from SAP?
The license key is sent to you in an e-mail message. Once you have received the license file, copy it onto your computer. Then restart SAP Business One. When the license query appears, add the license file to it. You can also download the license key in SAP Service Marketplace under the Internet address service.sap.com/licensekey choose SAP Solutions for SMB. For further information, see SAP Note 742024.
How can I change the file extension of the file attached to the mail from .txt.to lic.?
You must save the file locally on your computer before you change the extension. You must NOT change the content of the file.
Why is my license key only temporary?
If you request a license key for more users than you have licensed or for non-licensed components or your contract or hardware data are limited, you receive a license key that expires after 14 days. Request a license key with less user or contact your local SAP contracts department. For further information, see SAP Note 765296.
