Hello, I hope you are doing well!
When I am trying to refresh a tabular data model within visual studio that is using a Oracle data source; I am getting the following error message :
Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] An error happened while reading data from the provider: 'Object reference not set to an instance of an object.'
NB : the refresh is working when I deployed the model on a ssas tabular model instance( weird)
any idea please ?
Thnaks in advance
