After a Full Load test is completed and Change Processing is enabled, the goal is to test only the Change Data Capture (CDC) functionality. The 'Start Change Processing Only' option, found under 'Advanced Run Options,' is specifically designed for this scenario. It instructs Qlik Replicate to bypass the Full Load phase entirely and begin capturing and applying changes from the source system from the point the Full Load ended, or a specified point in time. This provides a direct and efficient method to validate the CDC configuration.

A. 'Reload Target' would unnecessarily re-run the entire Full Load, which has already been successfully tested, wasting time and resources.

B. Re-creating the task is a drastic and inefficient action when the existing task configuration is correct and only needs to be run in a different mode.

C. 'Resume Processing' is the standard operation to continue a task. While it would start CDC after a full load, 'Start Change Processing Only' is the more explicit and precise method for isolating and testing only the CDC part.

1. Qlik Replicate User Guide, "Starting a task in Change Processing only mode": This section explicitly states, "You may want to start a task in Change Processing only mode when the target tables have already been loaded with the source data (either by a third-party tool or by a previous Replicate task)." This directly aligns with the scenario where a Full Load test has already been completed.

2. Qlik Replicate User Guide, "Using the Advanced Run Options dialog box": The documentation details the advanced options available when running a task. It describes the ability to start processing changes from a specific time or log position, which is the underlying mechanism for the 'Start Change Processing Only' mode, allowing the user to bypass the Full Load phase.
