Additional Information

After further review, this issue will be closed. There are three separate issues that are occurring with this support issue. First, empty output with CSV input/target – the warning 000595 and empty output with CSV files can be reproduced. This will be addressed with BUG-000178272. Second, when the Optimize Performance for Feature Services parameter is enabled in ArcGIS Pro 3.5.2, the Append tool completes with a runtime of approximately 5 seconds using the test data, which leverages the Append API on the server side. When the parameter is disabled, the Append tool utilizes ApplyEdits on the client side. In this case, the tool completes successfully but with lower performance compared to when the parameter is enabled. This behavior is a known limitation. Third, in ArcGIS Pro 3.5 and later, the Optimize Performance for Feature Services parameter is available only for feature services accessed by accounts with Data Administrator/Owner privileges. This issue is being tracked in an internal development ticket and will be fixed in a future release. The fix will introduce an Enable Append option during publishing, allowing non-Admin/Owner accounts to access the Optimize Performance for Feature Services parameter.

Workaround

Run the tool with the 'Optimize performance for feature services' parameter unchecked. This allows the tool to run successfully without producing empty output.
