• What is the cause and solution for SAP error message VMP_MSG184 - MBOM item reordering between operations not allowed ?

  The SAP error message VMP_MSG184 indicates that there is an issue with the reordering of items in a Manufacturing Bill of Materials (MBOM) between operations. This typically occurs in the context of production planning and execution, where the system is trying to process a manufacturing order but encounters a configuration or data issue.
  Cause:
  The error can be caused by several factors, including:
  
  Incorrect Configuration: The routing or BOM may not be set up correctly, leading to conflicts in the order of operations.
  Item Assignment: Items may be assigned to operations in a way that does not allow for reordering. For example, if an item is required in multiple operations, the system may restrict reordering to maintain the integrity of the production process.
  Production Order Status: The status of the production order may not allow for changes to the sequence of operations.
  Dependencies: There may be dependencies between operations that prevent reordering, such as specific sequences that must be followed for safety or quality reasons.
  
  Solution:
  To resolve the error, consider the following steps:
  
  Check Routing and BOM: Review the routing and BOM configuration to ensure that they are set up correctly. Make sure that the items are assigned to the correct operations and that the sequence is logical.
  Review Production Order: Check the status of the production order. If the order is already in process, you may need to stop or complete certain operations before making changes.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on MBOM and routing configurations.
  Adjust Item Assignment: If necessary, adjust the assignment of items to operations to allow for reordering. This may involve changing the sequence of operations or reassigning items to different operations.
  Contact Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance based on your specific configuration and business processes.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CA01 (Create Routing), and CA02 (Change Routing) to manage BOM and routing configurations.
  Training and Documentation: Ensure that users involved in production planning and execution are trained on the proper procedures for managing BOMs and routings to minimize errors.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
