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 found one excel based tool but it is used for one universe at a time. I am looking for some java code which can pull Universe metadata information like tables, columns, joins, objects, classes etc.
