Implemented a dozen of SAP notes for the on-prem version 1709 SP01. "Campaigns" app is now not opening, because of an error in the gateway - "Property (external name) 'A6E9W9Y76K7AKZLKF5SL81168F_F' not found for entity 'CUAN_CAMPAIGN_METRICS_Q001Result" is returned by the service cuan_campaign_srv.
In the dev all is right.
Tried to clear caches, deactivate, then activate the service, nothing helps. Anything you could suggest?
