How To Fix KP286 - Iteration terminated after &V1& steps

SAP Error Message - Details

• Message type: E = Error

• Message class: KP - CO-OM Planning

• Message number: 286

• Message text: Iteration terminated after &V1& steps

What causes this issue?

The iteration of &V3& in controlling area &V2& was exited after &V1&
steps. After these steps, the convergence criterion is not yet
completely reached. A delta of &V4& remains.

System Response

The prices are established based on the currently calculated values.

How to fix this error?

Check the results; you can still update price calculation if the
results are precise enough. You can also start the divergence analysis
to trace possible loops that cause a divergence.

• What is the cause and solution for SAP error message KP286 - Iteration terminated after &V1& steps ?

  The SAP error message KP286, which states "Iteration terminated after &V1& steps," typically occurs in the context of cost planning or cost center accounting when the system is unable to converge on a solution after a specified number of iterations. This can happen during the execution of planning functions that require iterative calculations, such as when using the cost planning functionality in SAP Controlling (CO).
  Causes:
  
  Complexity of the Model: The planning model may be too complex, leading to difficulties in convergence.
  Incorrect Data: There may be incorrect or incomplete data in the master data or transaction data that affects the calculations.
  Parameter Settings: The settings for the planning run may not be optimal, such as the maximum number of iterations allowed.
  Circular References: There may be circular references in the planning logic that prevent the system from reaching a solution.
  Resource Limitations: Insufficient system resources (memory, processing power) can also lead to this error.
  
  Solutions:
  
  Review Data: Check the master data and transaction data for completeness and correctness. Ensure that all necessary data is available for the planning run.
  Adjust Iteration Settings: Increase the maximum number of iterations allowed in the planning settings. This can sometimes help the system to converge on a solution.
  Simplify the Model: If possible, simplify the planning model to reduce complexity. This may involve breaking down the planning process into smaller, more manageable parts.
  Check for Circular References: Review the planning logic for any circular references and resolve them.
  Monitor System Resources: Ensure that the system has adequate resources to perform the calculations. This may involve checking memory usage and processing power during the planning run.
  Use Debugging Tools: Utilize SAP debugging tools to trace the execution of the planning function and identify where the process is failing.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like KP06 (Cost Center Planning) or KP26 (Activity Type Planning) to review and adjust your planning data.
  SAP Notes: Check for any relevant SAP Notes that may address known issues related to this error message.
  Documentation: Review SAP documentation for cost planning and controlling to understand the parameters and settings that can affect the planning process.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or reach out to SAP support for further assistance.
