I have created a new Section using Section Wizard. I have added an Owner field there (UsrOwner) which has the Contacts lookup as a Data Source, and or course, I get the full Contacts list available for selection. How can I add a filter for this field. I am using BPMOnline Sales 7.5.0.627
In order to do that you need to go to the accounts section and switch to the extended filtration mode. Here you need to set up filter as shown on the figure below
After that you just add another condition inside this filter where you select specific campaign.
