I am trying to implement variant management for smarttable for which the backend is generated from CDS view through OData.publish: 'true'.
In the smarttable control definition, I have entered the persistenceKey and also the showVariantManagement to true.
But I am not able to see the 'Save' button in the table personalization dialog and also when I click the variants diaply button, it is showing the following message.
I am new to using the cds based odata. Is there something which I am missing at the backend side or frontend side?
