Configuration Issues: There could be configuration settings that prevent the actual update from occurring. Data Integrity Issues: The data being processed may not meet the necessary criteria for an update, leading to a simulation without execution.
Solution: Check Simulation Mode: Ensure that the transaction is not set to run
