We had an issue that Sync data never completed incident # 105053. I received an email from the support telling me the cause is the Oracle connectors dropping PKs for composite PKs on 10/3/2022 and that you are working to resolve it. But I got another email asking me to submit a new incident to resolve this issue. The connector is ckclora1_onecalp (paused) and ckclora1_onecalp2 (sycing data 4 days already).
