Hi Taek,
I had this problem in September and i opened a incident to SAP. The SAP Support answer was that Lumira only connect with non multi-tenanted system and that this problem would be resolved next version (1.29). Was created the SAP notes number 2223354. In the Last friday was liberated the 1.29.2 version but today i tested and still not work with Hana Multitenant.
In September i solved with a workarround using the SAP BO Universe on Hana and connected with Universe connector in SAP Lumira. It's work fine.
Thanks,
Igor Valle
