• What is the cause and solution for SAP error message CY379 - Planned order & / operation &: Requirements can not be split ?

  The SAP error message CY379 indicates that there is an issue with splitting planned orders or operations in the production planning module. This error typically arises when the system is unable to split the requirements for a planned order or operation due to certain constraints or settings.
  Cause:
  
  
  Non-Splittable Requirements: The planned order or operation may have been set up in such a way that it cannot be split. This can happen if the order is linked to certain characteristics that prevent splitting, such as specific production versions or batch management settings.
  
  
  Capacity Constraints: If there are capacity constraints in the production resources, the system may not be able to split the order to meet the requirements.
  
  
  Order Type Settings: Certain order types may have settings that do not allow splitting. This can be configured in the order type settings in the SAP system.
  
  
  Material Master Settings: The material master record may have settings that prevent splitting, such as specific planning strategies or lot sizing procedures.
  
  
  Dependencies and Relationships: If there are dependencies or relationships between operations that do not allow for splitting, this error can occur.
  
  
  Solution:
  
  
  Check Order and Operation Settings: Review the settings of the planned order and operations to ensure that they are configured to allow splitting. This includes checking the order type and any associated settings.
  
  
  Review Material Master Data: Check the material master data for the relevant material to ensure that the planning strategy and lot sizing procedures allow for splitting.
  
  
  Adjust Capacity Planning: If capacity constraints are causing the issue, consider adjusting the capacity planning settings or re-evaluating the production schedule to allow for splitting.
  
  
  Use Alternative Planning Strategies: If the current planning strategy does not allow for splitting, consider using an alternative strategy that does.
  
  
  Consult SAP Documentation: Refer to SAP documentation or help resources for specific configuration settings related to planned orders and operations.
  
  
  Contact SAP Support: If the issue persists and cannot be resolved through configuration changes, consider reaching out to SAP support for further assistance.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as MD04 (Stock/Requirements List) or CO02 (Change Production Order) to analyze the planned orders and their requirements.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on configuration settings.
  User Exits and BAdIs: If custom logic is implemented in your SAP system, check for any user exits or BAdIs that may affect the splitting of planned orders.
  
  By following these steps, you should be able to identify the cause of the CY379 error and implement a solution to resolve it.
