• What is the cause and solution for SAP error message RSENQ057 - Sort the aggregate catalog locked by &1 ?

  The SAP error message RSENQ057, which states "Sort the aggregate catalog locked by &1," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the aggregate catalog being locked by a user or process. This can prevent other processes from accessing or modifying the aggregate catalog, leading to the error message.

  Locking by Another User/Process: The aggregate catalog is locked by another user or process, which can happen during data loading, reporting, or when performing maintenance tasks.
