Hi Team,
From the attachment, i can guess that you want RFC SDK on linux but in that i can't find the version. That is fine we can go for n-1 version. you can also check for note 2451423 which can brief you with the version which will be out of support.
Moreover, further adding i will be following note 1025361 for your installation of NW RFC SDK with version 7.20 on linux environment.
I am 4.6 years experience with implementation of SAP products on linux from scratch(creating the volume group, logical group and further on with sap pre-requisite.)
Thanks and Regards,
Priyanshu Srivastava
