Block relations are very similar to client side filters used in Screen Blocks but block relations uses dynamic data for filtering.
This provides option to configure cases when row selected in one screen block would trigger to filter data in another screen block by some field.
To show list of block relations select desired Screen in Project Explorer and press Block Relations tab (right to Presentation tab).
There is a special form to add or edit block relationships.
Primary block - block that would trigger a refresh event.
Foreign block - is a block that would be filtered.
If several fields are selected they would be combined with AND logic in the filter.
