Unhandled event loop exception in SAP Design Studio

Hello Everyone,

I'm working with SAP Design Studio and so far I can connect to the BI Platform without any problem,

But when I try to add an .unx data source I get the following error:

Unhandled event loop exception

Am I missing something? it's a weird behavior because a colleague can add an .unx data source without any problem by using my user,

My SAP DS version is "1.6 SP4 Patch 2 (Version: 16.4.2)"

Thank you in advance.

    Hello Jose - please see the Design Studio BI Platform wiki https://wiki.scn.sap.com/wiki/display/BOBJ/Design+Studio+BI+Platform+Support

    It says "The error message about the following occurs while trying to create a calculation measure in SAP Design Studio:

    "Unhandled event loop exception"
    This issue is occurring because the runtime (simple) calculation is not supported for Universe data sources as per the Application Designer Guide (http://help.sap.com/businessobject/product_guides/AAD16/en/ds_16SP02_user_en.pdf) page 32."
