• What is the cause and solution for SAP error message C2156 - Processing steps not in continuous sequence ?

  The SAP error message C2156, which states "Processing steps not in continuous sequence," typically occurs in the context of production orders or process orders. This error indicates that the system has detected a discontinuity in the sequence of processing steps defined for a particular order. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Non-Sequential Processing Steps: The processing steps defined in the order are not in the expected sequential order. For example, if step 3 is defined before step 2, the system will raise this error.
  Missing Steps: There may be steps that are defined in the routing or recipe that are not included in the order, leading to a gap in the sequence.
  Incorrect Configuration: The configuration of the routing or the production process may not align with the expected sequence of operations.
  Manual Changes: If manual changes were made to the order or routing, it could lead to inconsistencies in the sequence.
  
  Solution:
  
  Check the Order: Review the production or process order to ensure that all processing steps are included and are in the correct sequence.
  Review Routing/Recipe: Check the routing or recipe associated with the order to ensure that the steps are defined correctly and in the proper order.
  Adjust Sequence: If you find that the steps are out of order, you may need to adjust the sequence in the order or the routing to ensure continuity.
  Recreate the Order: In some cases, it may be easier to recreate the order with the correct sequence of steps rather than trying to adjust the existing one.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the configuration of routing and production orders.
  
  Related Information:

  Error Logs: Check the error logs or system messages for additional context or related errors that may provide more insight into the issue.
