• What is the cause and solution for SAP error message /SAPAPO/CIF420 - Manual reservation &1 exists in APO without active integration model ?

  The SAP error message /SAPAPO/CIF420 Manual reservation &1 exists in APO without active integration model typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is a manual reservation in the APO system that is not linked to an active integration model in the Core SAP system (like SAP ERP). This can lead to inconsistencies in data synchronization between the two systems.
  Cause:
  
  Manual Reservation: A manual reservation has been created in the APO system for a specific material or resource.
  Inactive Integration Model: The integration model that should synchronize data between the SAP ERP and APO systems is either inactive or not set up correctly for the relevant material or resource.
  Data Synchronization Issues: The absence of an active integration model means that the manual reservation cannot be processed or recognized by the system, leading to this error.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Integration Model:
  
  Go to transaction code CIF in the SAP ERP system.
  Check if there is an active integration model for the relevant material or resource.
  If not, create or activate the integration model that includes the necessary objects (materials, plants, etc.).
  
  
  
  Create/Activate Integration Model:
  
  If an integration model does not exist, create a new one using transaction CIF and include the relevant materials and plants.
  If an integration model exists but is inactive, activate it.
  
  
  
  Review Manual Reservations:
  
  In the APO system, check the manual reservations that are causing the error. You can use transaction /SAPAPO/RES01 to view reservations.
  If necessary, you may need to delete or adjust the manual reservation if it is no longer needed or if it conflicts with the integration model.
  
  
  
  Re-run CIF Integration:
  
  After making the necessary changes, re-run the CIF integration to ensure that the data is synchronized correctly between the systems.
  
  
  
  Check for Other Errors:
  
  If the issue persists, check for other related error messages or logs that might provide additional context or information about the problem.
