• What is the cause and solution for SAP error message CO685 - Only collective requirements are possible for material & ?

  The SAP error message CO685 ("Only collective requirements are possible for material &") typically occurs in the context of production planning and control, particularly when dealing with collective requirements in the SAP system. This error indicates that the system is expecting collective requirements for a specific material, but the current operation does not meet that requirement.
  Cause:
  
  Material Configuration: The material in question may be configured to only allow collective requirements. This is often the case for materials that are managed in a way that requires aggregation of demand.
  Order Type: The order type being used may not support individual requirements for the material.
  Planning Strategy: The planning strategy assigned to the material may dictate that only collective requirements are allowed.
  Master Data Issues: There may be inconsistencies or missing data in the material master or related master data that prevent the system from processing individual requirements.
  
  Solution:
  
  
  Check Material Master: Review the material master data for the affected material. Ensure that the settings for collective requirements are correctly configured.
  
  Go to the material master (transaction code MM03) and check the MRP views.
  Look for the "Collective Requirements" checkbox and ensure it is set according to your business needs.
  
  
  
  Review Order Type: Ensure that the order type you are using is compatible with the requirements of the material. If necessary, switch to an order type that supports individual requirements.
  
  
  Adjust Planning Strategy: If the planning strategy is set to one that only allows collective requirements, consider changing it to a strategy that allows for individual requirements if that aligns with your business process.
  
  
  Check for Open Orders: If there are open production orders or purchase orders that are conflicting with the new requirements, resolve those conflicts.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's SAP support team for specific guidance related to your configuration and business processes.
  
  
  Testing: After making changes, perform tests to ensure that the error no longer occurs and that the system behaves as expected.
