license key for Portal_MSS , NetWeaver_MSS , J2EE-Engine_MSS,

Hello

I wander is it something special to be done in order to prolong license key for Portal_MSS , NetWeaver_MSS , J2EE-Engine_MSS,

Last time I installed all (on marketplace with expiration date 31.12.9999).

However on portal system info I have

Software Product Days Until Expiry

Portal_MSS 10

Maintenance_ORA 9

NetWeaver_MSS 10

J2EE-Engine_MSS 10

NetWeaver_ORA 2918045

Maintenance_MSS 10

I would namely like to have also

Portal_MSS

NetWeaver_MSS

J2EE-Engine_MSS,

Days until Expiry 2918045 but how to achieve that?
