  The SAP error message B1122, which states "Specify a server group when using parallel processing," typically occurs in the context of background processing or parallel processing in SAP systems. This error indicates that the system requires a specific server group to be defined for the parallel processing task you are trying to execute.
  Cause:
  The error arises when:
