    - question: Does Azure Synapse Link support calculated columns?
      answer: |
-        Yes. In Dataverse, the calculated column keeps only the formula information and the real value depends on the base entity column so the calculated column will be updated if and only if all data (base tables) related to calculated columns are exported via Azure Synapse Link.
+        Calculated columns are only supported when the lookup field is located within the same table.
    - question: Which Dataverse tables use append only mode by default?
      answer: |
         All tables that do not have a createdOn field will be synced using append only mode by default. This includes relationship tables as well as the ActivityParty table.
