• What is the cause and solution for SAP error message PV402 - Different objects (resource and reservation) have been selected ?

  The SAP error message PV402, which states "Different objects (resource and reservation) have been selected," typically occurs in the context of resource planning and scheduling within SAP, particularly in modules like SAP Project System (PS) or SAP Production Planning (PP). This error indicates that there is a mismatch between the resources and the reservations that have been selected for a particular operation or task.
  Cause:
  The error can arise due to several reasons:
  
  Mismatched Resource and Reservation: The resource you are trying to use does not match the reservation that has been made. For example, if a reservation is made for a specific machine, but you are trying to assign a different machine to the same task.
  Incorrect Configuration: There may be configuration issues in the resource planning settings or in the way the resources and reservations are defined in the system.
  Data Entry Errors: Manual entry errors when creating or selecting resources and reservations can lead to this mismatch.
  Resource Availability: The selected resource may not be available for the time period of the reservation, leading to a conflict.
  
  Solution:
  To resolve the PV402 error, you can take the following steps:
  
  
  Verify Resource and Reservation:
  
  Check the resource that is being selected and ensure it matches the reservation. You can do this by reviewing the details of both the resource and the reservation in the system.
  
  
  
  Adjust Reservations:
  
  If the resource is correct, consider adjusting the reservation to match the selected resource. This may involve changing the reservation details or creating a new reservation for the correct resource.
  
  
  
  Check Configuration:
  
  Review the configuration settings for resources and reservations in the SAP system. Ensure that they are set up correctly and that there are no discrepancies.
  
  
  
  Review Availability:
