On Dec 4th 2019 onwards, a new mandatory field is required for Facebook Campaigns.
This will also impact Facebook campaign creation in SAP Marketing.
For new campaigns on-premise customers have to apply note “2858267 – Facebook Special Ad Category for Campaign”. Without that note, creation of Facebook Campaigns will not be possible any more after Dec 4th.
Cloud customer will get an hotfix for this changes.
I hope this information helps you to know about this new field and use in Facebook campaigns .
