How To Fix CO235 - Smallest op. no. in parallel seq. & is smaller than the branch op. no.

SAP Error Message - Details

• Message type: E = Error

• Message class: CO - PPC order processing messages

• Message number: 235

• Message text: Smallest op. no. in parallel seq. & is smaller than the branch op. no.

What causes this issue?

You are trying to create a parallel sequence. The smallest operation
number in the parallel sequence is, however, smaller than the number
of the branch operation.

How to fix this error?

Within a parallel sequence, you can only enter numbers, which are
greater than the number of the branch operation and
smaller than the number of the return operation.

• What is the cause and solution for SAP error message CO235 - Smallest op. no. in parallel seq. & is smaller than the branch op. no. ?

  The SAP error message CO235 indicates that there is an issue with the operation numbers in a production order or routing. Specifically, it means that the smallest operation number in a parallel sequence is smaller than the operation number of a branch operation. This can occur in scenarios where you have parallel sequences in your routing, and the system is unable to determine the correct sequence of operations due to the numbering.
  Cause:
  
  Operation Numbering: The operation numbers in a parallel sequence must be sequential and should not overlap with the operation numbers of branch operations.
  Routing Configuration: There may be a misconfiguration in the routing where the operation numbers are not set correctly, leading to conflicts.
  Manual Changes: If operations have been manually renumbered or modified, it can lead to inconsistencies in the operation sequence.
  
  Solution:
  
  Check Operation Numbers: Review the operation numbers in the routing. Ensure that the smallest operation number in the parallel sequence is greater than or equal to the operation number of the branch operation.
  Adjust Routing: If necessary, adjust the operation numbers in the routing to ensure they follow a logical sequence without conflicts. This may involve renumbering operations to maintain the correct order.
  Use Transaction Codes: Use transaction codes like CA01 (Create Routing) or CA02 (Change Routing) to access and modify the routing details.
  Validate Routing: After making changes, validate the routing to ensure that there are no further conflicts. You can use transaction C223 to check the routing structure.
  Consult Documentation: If you are unsure about the correct operation numbering, refer to SAP documentation or consult with a colleague who has experience with routing in SAP.
  
  Related Information:
  
  Parallel Sequences: In SAP, parallel sequences allow multiple operations to be performed simultaneously. Understanding how to configure these correctly is crucial for efficient production planning.
  Branch Operations: These are operations that can be executed based on certain conditions or decisions in the production process. Properly managing their operation numbers is essential to avoid conflicts.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on routing configurations.
  
  By following these steps, you should be able to resolve the CO235 error and ensure that your routing is correctly configured for production.
