Unique System Numbers for Old License Keys  

As of SAP Web AS 6.10, a unique system number is automatically assigned when the license key is released.

There are two exceptions to this:

●      The SYSTEM-NO. of the new license is "INITIAL_SYSTEM_IDX"

●      All old licenses have "INITIAL_SYSTEM_IDX".

However only one SID is ever affected. If there are licenses for several SIDs in the system, only the SID specified in the new license is relevant. The new field is displayed on the initial screen of Transaction SLICENSE.

Old Licenses Without System Numbers

You can still install old licenses that do not have a SYSTEM-NO. When you are asked to enter the details leave the SYSTEM-NO empty (do not enter blank characters, just confirm with Enter) and then enter the other data. The SYSTEM-NO will be given the value "INITIAL_SYSTEM_IDX". The old license is then valid as normal.

How Does the Upgrade Work?

When a system is upgraded, all old licenses in the system are also upgraded. In other words, SYSTEM-NO. gets the value "INITIAL_SYSTEM_IDX". The table is then updated. The following occurs:

...

       1.      Read out licenses.

       2.      Update licenses, that is, assign them a SYSTEM NO.

       3.      Delete table

       4.      Recreate table

       5.      Insert licenses
