• What is the cause and solution for SAP error message WSTI_CALC002 - Enter server group for parallel processing ?

  SAP Error Message:
  
  WSTI_CALC002 Enter server group for parallel processing
  
  Cause:
  This error occurs when you are trying to execute a task or process in SAP that requires parallel processing, but the system does not have a server group specified for this parallel processing. In other words, the system expects you to define or select a server group that will handle the parallel execution of the workload, but this information is missing.
  Typically, this happens in scenarios involving background jobs, batch input sessions, or other processes that can be distributed across multiple application servers to improve performance.
  
  Explanation:
  
  Server Group: A server group in SAP is a logical grouping of application servers. When a process supports parallel processing, it can distribute the workload across the servers in the specified group.
  If no server group is specified, the system cannot determine where to run the parallel tasks, hence the error.
  
  
  Solution:
  
  
  Specify a Server Group:
  
  When scheduling the job or running the process, enter a valid server group name in the field for parallel processing.
  You can find or create server groups in transaction SM61 or SMMS (Server Group Maintenance).
  
  
  
  Check Server Group Configuration:
  
  Use transaction SMMS to verify if server groups exist and which application servers belong to them.
  If no server group exists, create one and assign the relevant application servers.
  
  
  
  Adjust Job or Process Settings:
  
  In the job scheduling or process execution screen, ensure the server group field is filled.
  If the process does not require parallel processing, you may disable or skip the parallel processing option.
  
  
  
  Consult Basis Team:
  
  If you do not have authorization or knowledge to manage server groups, contact your SAP Basis team to set up or provide the correct server group.

  Parallel Processing:
  
  Used to improve performance by distributing workload.
  Requires proper configuration of server groups.
  
  
  
  
  Summary:
  
  Cause: Missing server group specification for parallel processing.
  Solution: Enter a valid server group name for parallel processing or configure server groups in the system.
  Check: Server group setup in SMMS and assign application servers accordingly.
