• What is the cause and solution for SAP error message MW674 - Either all or no parallel processing parameters must be entered ?

  The SAP error message MW674 ("Either all or no parallel processing parameters must be entered") typically occurs when you are trying to execute a transaction or report that involves parallel processing, but the system detects that the parameters for parallel processing are not correctly set. This can happen in various contexts, such as during the execution of background jobs or when using certain transaction codes that support parallel processing.
  Cause:
  The error arises when:
  
  You have partially filled in the parameters for parallel processing (e.g., specifying some parameters but not others).
  You have not specified any parameters at all when the system expects them to be defined.
  The system requires that either all parameters related to parallel processing must be filled in or none at all.
  
  Solution:
  To resolve this error, you should:
  
  
  Check Parallel Processing Parameters: Ensure that you have either filled in all the required parameters for parallel processing or left them all blank. The parameters typically include:
  
  Number of parallel processes
  Maximum number of parallel processes
  Other relevant settings depending on the specific transaction or report.
  
  
  
  Review Documentation: Consult the documentation for the specific transaction or report you are using to understand the required parameters for parallel processing.
  
  
  Adjust Settings: If you want to use parallel processing, make sure to enter all necessary parameters. If you do not want to use parallel processing, ensure that all related fields are left empty.
  
  
  Test the Changes: After making the necessary adjustments, try executing the transaction or report again to see if the error persists.
