Hi, Iād like to add a one2many relationship between Campaigns and Products, and āCampaignsā and āEventsā
In a subpanel form, as far as I know, I should modify
suitecrm/modules/Campaigns/metadata/subpaneldefs.php
File, but I donāt understand which of these relations should I take as an example.
Could someone put me in the right direction on this?
