• What is the cause and solution for SAP error message CURTO1051 - A concurrent initial data transfer has already been started ?

  The SAP error message CURTO1051 indicates that a concurrent initial data transfer has already been started, which means that the system is currently processing an initial data transfer for a particular object or process, and another attempt to start a similar transfer is being blocked.
