If so, you need SAP Universal ID. In a few months, SAP Universal ID will be the only option to login to SAP Community. Without it, you will lose your content and badges. If you have multiple accounts, use the Consolidation Tool to merge your content.
I have one doubt related to edition, suppose my edition is valid form Today to 03/2016 and during this I have changed value of any field for example short key to 001 to 002.
What would happen after 04/16 ? what would be short key value ?
