Any suggestions?

Thanks in advance!

Hi,

can you confirm the version of Essential Viewer that you are using? You should be able to see it in the bottom right corner of any view.

Thanks,

Jason

Hi Jason,
the version is 6.2.

Hi, problem solved. As it states in error message, the second paramter cannot be empty (business_activity_used). For some strange reason i missed to enter the name of it..

Thanks!
