This system's system number is "1234567890" but there is a license key for system number "0987654321" in the license key file.

I just wanted to install a new incense in my test system. I deleted the existing ones and tried to install the new one in SLICENSE transaction. The new license came with different system number.

The problem

Following error message appeared:

This system's system number is "<10-digit number>" but there is a license key for system number "<another 10-digit number>" in the license key file.

The background

The reason behind was that "System Number" could not get empty but even after deleting the license it was the same as before.

• I checked the content of license table using
  saplikey pf=/sapmnt/<SID>/profile/<instance profile> -show
  command
• I tried to delete it again using
  saplikey pf=/sapmnt//profile/<instance profile> -delete "*" "*" "*"
  command
• Tried to empty table buffer via /$TAB in OK-code field
• Tried to empty all buffers via /$SYNC in OK code field
  
  

but none of them was successful.

The solution

• I had to delete old type of license, following
  SLICENSE: License with new installation number cannot be installed - Application Server Infrastructu...
• Afterwards system number got empty ("System No. Empty") and I could install the new license normally.

Hope this information will be helpful for you as well.
