Report with "or" condition

Hi there.

How can I get an report about Contact which have the fields “Emailadress” or “office phone” or “mobile” empty ?

Over the wizard I cannot find option to work with “OR” or “AND” etc…

Best regards,

Can’t currently do this out of the box.

You may create custom action and get desired output. Required some customization.

OK. Let me try something easier.

How can I show all contacts where Emailadress is “empty” ?

What character must I give to the Value Field to get this “empty” ?
