• What is the cause and solution for SAP error message COSE100 - Seq. &, op. &: Simultaneous dispatching and deallocation not possible ?

  The SAP error message COSE100, which states "Simultaneous dispatching and deallocation not possible," typically occurs in the context of production order processing, particularly when dealing with operations in a production order. This error indicates that there is an attempt to simultaneously dispatch (start) and deallocate (cancel) an operation in a production order, which is not allowed.
  Cause:
  
  Concurrent Operations: The error arises when there is an attempt to perform two conflicting actions on the same operation in a production order. For example, if an operation is being dispatched while another process is trying to deallocate it, SAP will throw this error.
  System Configuration: There may be specific configurations or settings in the system that prevent simultaneous actions on operations.
  User Actions: A user might have inadvertently triggered both actions at the same time, possibly through a custom transaction or a batch job.
  
  Solution:
  
  Check Current Status: Verify the current status of the operation in the production order. Ensure that the operation is not already in a dispatched state before attempting to deallocate it.
  Sequential Processing: Ensure that operations are processed sequentially. If you need to deallocate an operation, do so first before attempting to dispatch it.
  Review User Actions: If this error is occurring frequently, review the user actions or processes that lead to this error. Ensure that users are trained to avoid simultaneous actions on the same operation.
  System Logs: Check system logs for any additional information or related errors that might provide more context on why this error is occurring.
  Consult Documentation: Refer to SAP documentation or notes related to production order processing for any specific guidelines or known issues related to this error.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO02 (Change Production Order) and CO03 (Display Production Order) to manage production orders effectively.
  SAP Notes: Look for SAP Notes that might address this specific error or provide patches or updates that could resolve underlying issues.
  User Exits and BAdIs: If custom logic is involved, check for any user exits or BAdIs that might be affecting the dispatching and deallocation processes.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or reach out to SAP support for further assistance.
