Integration of .unx Universe in MS Excel

Hi All,

i have the following Problem. I use Webi reports based on a .unx Universe which are build up on a relational connection. The database is a Oracle database which is used by the MES-System. On the one hand the employees use the Webi reports to analyze/report production data, on the other hand they want a Office 365 (Excel) integration of the .unx Universe.

1) The first way i want to go is SAP BusinessObjects Live Office, but it don't support .unx Universes.

2) The SAP BusinessObjects Analysis, edition for Microsoft Office don't support Universes, too.

3) The third way is the Query as a webservice tool and the Add-on Infopath from Microsoft, but since this year Microsoft don't support InfoPath loud Wikipedia.

4) The only way i found is the Microsoft Power Query Connectivity Add-on for Microsoft Excel.

Is this actually the only path to integrate .unx Universe queries direct to MS-Excel?  I don't find a Roadmap of SAP BusinessObjects Live Office?Which way the SAP want to go with this Add-on in the future?

Regards,

Arne
