License expiration date has no value
I have a AS ABAP ECC 6.0 system whose INITIAL license expired two days ago.
I finally got the permanent license for the system and I logged on as SAP* and executed the SLICENSE transaction. I installed the permanent license and it appears with green status (Succesfully installed) but the fact is that in current settings tab, the License Expiration date appears to be the date of expiration of the INITIAL license.
I managed to delete the INITIAL license with the command saplicense -delete, but now the License Expiration date shows no value.
Because of that the system does not recognise the installed license and I cannot logon in the system with any user but SAP*.
Could anyone help me??
