• What is the cause and solution for SAP error message /ISDFPS/MM_CS042 - Sender of PO &1/&2 is not operational in the current logical system ?

  The SAP error message /ISDFPS/MM_CS042 Sender of PO &1/&2 is not operational in the current logical system typically occurs in the context of the SAP Integrated Business Planning (IBP) or SAP Supply Chain Management (SCM) systems. This error indicates that the system is unable to process a Purchase Order (PO) because the sender (the system or logical entity that created the PO) is not recognized as operational in the current logical system.
  Cause:
  
  Logical System Configuration: The logical system that is supposed to send or receive the Purchase Order is not properly configured or is inactive in the current environment.
  Master Data Issues: The sender's master data may not be set up correctly, or the sender may not be assigned to the correct logical system.
  Integration Issues: There may be issues with the integration settings between different SAP systems or between SAP and non-SAP systems.
  Transport Layer Issues: If the PO is being processed across different environments (e.g., Development, Quality, Production), the transport layer may not be correctly set up.
  
  Solution:
  
  
  Check Logical System Configuration:
  
  Go to transaction SM59 and check the RFC connections to ensure that the logical system is correctly defined and operational.
  Verify that the logical system is active and properly configured in the system landscape.
  
  
  
  Verify Master Data:
  
  Check the master data for the sender of the PO. Ensure that the sender is correctly defined in the system and is assigned to the appropriate logical system.
  Use transaction BD54 to check the assignment of logical systems.
  
  
  
  Integration Settings:
  
  Review the integration settings between the systems involved. Ensure that the necessary configurations for data exchange are in place.
  If using middleware (like SAP PI/PO), check the configuration there as well.
  
  
  
  Transport Layer:
  
  If the issue arises in a non-production environment, ensure that the transport layer is correctly set up and that all necessary transports have been imported.
  
  
  
  Check for System Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as sometimes bugs in earlier versions can lead to such issues.
