New Connection to SAP’s Support Backbone (OSS connection)
SAP’s support backbone or OSS connection, as it is also widely called, is the central infrastructure to provide technical support to SAP customers. The support backbone consists of several different systems for different purposes – for example, it provides the SAP Support Portal infrastructure, the Maintenance Planner, SAP EarlyWatch Alert Reports, and many more.
Support backbone gets an update and Customer action is required!
SAP’s support backbone has been updated. The legacy infrastructure remains in place to allow a safe transition. However, customers need to switch to the new infrastructure before January 2020 to ensure continuous connectivity.
Technically, the connection is changed from RFC-based to HTTPS-based communication.
This impacts every ABAP-based SAP system which is connected to the support backbone.
What do you need to do?
Modifications are necessary in transaction STC01 (Task Manager for Technical Configuration) for task list ‘SAP_BASIS_CONFIG_OSS_COMM’ – New OSS Communication:

The detailed steps that have to be executed are described and updated, if necessary, in this SAP Note: 2738426

Just FYI, this hit Reddit yesterday with some more technical details: https://www.reddit.com/r/SAP/comments/ary5f7/psa_2020_and_changes_yyou_must_do_on_all_abap/
I'd heard this morning on the radio that you can find any topic on reddit, but I really didn't believe it - until I was Jelena'd.
Yes, it's a one-stop shop for the cat videos and SAP support info. 🙂
What time zone are we in after all? Because it's 4:55PM RIGHT NOW on Feb. 19, and yet our comments are time-stamped 8:01PM and 8:48PM.
LOL, I'm definitely not out there at 9 pm posting random SCN comments. 🙂 Yours shows as 10 pm, so I'm guessing it's UTC (US Eastern time + 5)?
SCN is odd that way, e.g. once I wondered when exactly is "yesterday" here.
On a more relevant note, and although I am 100% sure my Basis team already knows this, I did forward the blog to them.
