  The SAP error message MQ157 typically indicates that a package is not in the expected postprocessing phase, which can occur during the processing of a message queue or during the execution of a transaction. This error can arise in various contexts, such as during the execution of a background job, data transfer, or when handling messages in the SAP system.

  Review Logs: Check the application logs (transaction SLG1) for any related error messages that might provide more context on why the package is not in the expected phase.
