How To Fix KV161 - WIP or scrap calculation for parallel operation sequences not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: KV - Variance Analysis for Cost Centers and Cost Objects

• Message number: 161

• Message text: WIP or scrap calculation for parallel operation sequences not possible

What causes this issue?

If the routing specifies a sequence of operations that are defined as a
parallel sequence, this will have the following effects:
The system cannot interpret the confirmed scrap quantities in cumulative
and periodic settlement when it calculates the scrap.
The system cannot calculate work in process (WIP) at target costs for
this order because it does not recognize the relevant operations.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you want to calculate scrap or WIP, do not define parallel sequences.

• What is the cause and solution for SAP error message KV161 - WIP or scrap calculation for parallel operation sequences not possible ?

  The SAP error message KV161 indicates that there is an issue with the Work in Progress (WIP) or scrap calculation for parallel operation sequences in a production order. This error typically arises when the system encounters difficulties in calculating WIP or scrap due to the way operations are defined in the routing or production order.
  Cause:
  
  Parallel Operations: The error often occurs when there are parallel operations defined in the routing, and the system is unable to determine how to allocate costs or calculate WIP for these operations.
  Missing or Incorrect Configuration: There may be missing configuration settings in the production order or routing that prevent the system from processing the parallel operations correctly.
  Inconsistent Data: Inconsistencies in the data related to the production order, such as incorrect operation sequences or missing components, can also lead to this error.
  Capacity Planning Issues: If the capacity planning settings are not correctly defined for the operations, it can lead to issues in calculating WIP.
  
  Solution:
  
  Check Routing and Production Order: Review the routing and production order to ensure that the operations are defined correctly. Make sure that the parallel operations are set up properly and that there are no inconsistencies.
  Review Configuration Settings: Check the configuration settings related to WIP and scrap calculations. Ensure that all necessary settings are in place for handling parallel operations.
  Adjust Operation Sequences: If possible, consider adjusting the operation sequences to avoid parallel operations or to simplify the calculation process.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling WIP and scrap calculations in the context of parallel operations.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide patches or updates that could resolve the issue.
  Testing: After making changes, perform testing to ensure that the WIP and scrap calculations are now functioning correctly.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as CO02 (Change Production Order) or CO03 (Display Production Order) to review and modify production orders.
  SAP Help Portal: The SAP Help Portal provides extensive documentation on production planning and control, including WIP and scrap calculations.
  Community Forums: SAP Community forums can be a valuable resource for finding solutions to specific errors, as other users may have encountered and resolved similar issues.
  
  If the problem persists after following these steps, it may be necessary to involve your SAP support team or a consultant with expertise in production planning and control.
