• What is the cause and solution for SAP error message I4311 - The simultaneous processing of operational steps is not allowed ?

  The SAP error message I4311, "The simultaneous processing of operational steps is not allowed," typically occurs in the context of production planning or order processing when there is an attempt to execute multiple operational steps that cannot be processed at the same time. This can happen in various scenarios, such as during the execution of production orders, maintenance orders, or when working with routing and operations in SAP.
  Causes:
  
  Concurrent Operations: The error often arises when there are multiple operations that are set to be executed simultaneously, but the system does not allow this due to dependencies or resource constraints.
  Resource Locking: If a resource (like a machine or work center) is already engaged in another operation, trying to start a new operation on the same resource can trigger this error.
  Incorrect Configuration: The configuration of the routing or production order may not allow for simultaneous processing of certain steps.
  Order Status: The status of the production or maintenance order may not permit the execution of certain operations concurrently.
  
  Solutions:
  
  Check Order Status: Ensure that the order you are trying to process is in the correct status that allows for the operations to be executed. If the order is already in process, you may need to wait until it is completed.
  Review Routing and Operations: Check the routing for the production order to ensure that the operations are defined correctly and that there are no conflicts in the sequence of operations.
  Resource Availability: Verify that the resources (machines, work centers) required for the operations are available and not locked by other processes.
  Adjust Configuration: If necessary, adjust the configuration settings in the routing or production order to allow for the desired processing sequence.
  Sequential Processing: If simultaneous processing is not allowed, consider restructuring the operations to be executed sequentially rather than concurrently.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message. Sometimes, there may be known issues or fixes provided by SAP.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO02 (Change Production Order), CO01 (Create Production Order), or IW32 (Change Maintenance Order) to manage orders effectively.
  Documentation: Review SAP documentation or help files related to production planning and order processing for more detailed guidance on managing operations and understanding dependencies.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in production planning or order management.
