• What is the cause and solution for SAP error message MILL_OC026 - Operation &1: More than one operation was selected from order &2 ?

  The SAP error message MILL_OC026 indicates that more than one operation has been selected for a specific order during a process, typically in the context of production or order management. This error can occur in various scenarios, such as when trying to confirm operations, perform a goods movement, or execute a production order.
  Cause:
  The primary cause of this error is that the system has detected multiple operations associated with the specified order, but the action being performed expects only one operation to be selected. This can happen due to:
  
  Incorrect Selection: The user may have inadvertently selected multiple operations instead of a single one.
  Order Configuration: The production order may have been configured in such a way that it allows multiple operations, but the transaction being executed does not support this.
  System Settings: There may be specific settings or configurations in the SAP system that dictate how operations are handled, leading to this error when those settings are not aligned with the user's actions.
  
  Solution:
  To resolve the MILL_OC026 error, you can take the following steps:
  
  
  Check Selection: Ensure that you are selecting only one operation when performing the action. Review the selection criteria and make sure to choose a single operation from the list.
  
  
  Review Order Details: Look into the production order details to understand how many operations are defined. You can do this by navigating to the production order in the SAP system and checking the operations tab.
  
  
  Adjust Configuration: If the order is meant to have multiple operations, consider whether the transaction you are using supports this. You may need to adjust your approach or use a different transaction that can handle multiple operations.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific transaction you are using to understand its limitations regarding operation selection.
  
  
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team or consulting with an SAP expert who can provide insights based on your specific configuration and usage.

  User Training: Ensure that users are trained on how to properly select operations and understand the implications of their selections in the context of production orders.
