BEx Analyzer - Add SAP ComboBox Control in VBA Userform

Hello,

I`like to insert a SAP ComboBox in a VBA Userform.

I added the control element (SAP ComboBox) to the VBA toolbox and tried insert the Combox in the VBA userform afterwards. The following error message appeared: " The subject is not trusted for the specified action".

Do I have to activate a particular library as well?

Thanks in advance

Daniel
