SAP GUI 620 Patch - Patch Level 12.

Hi,

I am working with SAP GUI 620 and connecting the server through Ilink. Ilink is supporting only SAP 620. I need to enhance my knowledge in ECC 5.0 & ECC 6.0. My main problem is recently i have downloaded one patch 69 to work with ECC 5.0 & 6.0.

When I apply the same it is asking about Patch Level 12 but I could not able to search for the same in SERVICE.SAP.COM.

Please guide how to get the same at the earliest.

Thanks in advance for the same.
