A new Account record is created in Opendata. But, it does not sync to the customer network through a Veeva Opendata Subscription.
The Opendata Master Instance does not run the cs_export job after the record is created. So, the Veeva Opendata Subscription cannot read the newly created record from the exported file.
To contact the Veeva Opendata team to run the cs_export job, open a ticket with Veeva Support and provide issue records VID.
