How To Fix CK730 - Cycle & not iterated due to cost estimate with errors

SAP Error Message - Details

• Message type: E = Error

• Message class: CK - Product Costing Messages

• Message number: 730

• Message text: Cycle & not iterated due to cost estimate with errors

What causes this issue?

Cycle &v1& was not iterated, because at least one of the materials in
the cycle was costed with errors (status KF), or because no structure
could be generated for a material.

System Response

The system continues costing the current costing level without
iterating cycle &v1&.

How to fix this error?

Have the system display the materials of the cycle costed with status
KF in the material overview. Using the log, establish the cause of the
error and remove it. Then repeat the cost estimate.

• What is the cause and solution for SAP error message CK730 - Cycle & not iterated due to cost estimate with errors ?

  The SAP error message CK730, which states "Cycle & not iterated due to cost estimate with errors," typically occurs during the cost estimation process in SAP, particularly when dealing with product costing. This error indicates that the system has encountered a cycle in the cost estimate that it cannot resolve due to existing errors in the cost components or the structure of the cost estimate.
  Causes of CK730 Error
  
  
  Circular References: There may be circular references in the cost components or in the structure of the cost estimate. This can happen if a cost element refers back to itself or if there are interdependencies that create a loop.
  
  
  Missing Master Data: Required master data (like material master, BOM, routing, etc.) may be missing or incorrectly configured, leading to errors in the cost estimate.
  
  
  Incorrect Costing Variants: The costing variant used may not be set up correctly, or it may not be compatible with the materials or processes being costed.
  
  
  Errors in Cost Components: There may be errors in the cost component structure, such as incorrect formulas or missing values.
  
  
  Inconsistent Data: Inconsistencies in the data used for the cost estimate, such as incorrect prices or quantities, can also lead to this error.
  
  
  Solutions to CK730 Error
  
  
  Check for Circular References: Review the cost components and the structure of the cost estimate to identify and eliminate any circular references.
  
  
  Validate Master Data: Ensure that all necessary master data (material master, BOM, routing, etc.) is complete and correctly configured. Check for any missing or incorrect entries.
  
  
  Review Costing Variants: Verify that the costing variant being used is appropriate for the materials and processes involved. Make adjustments as necessary.
  
  
  Analyze Cost Components: Check the cost component structure for any errors. Ensure that all formulas and values are correct and that there are no missing components.
  
  
  Run Consistency Checks: Use SAP's consistency check tools to identify and resolve any inconsistencies in the data used for the cost estimate.
  
  
  Debugging: If the issue persists, consider using debugging tools to trace the cost estimate process and identify where the error is occurring.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to the CK730 error and cost estimation processes.
  
  
  Related Information
  
  Transaction Codes: You may use transaction codes like CK11N (Create Cost Estimate) or CK40N (Change Cost Estimate) to review and modify cost estimates.
  SAP Notes: Check SAP Notes for any known issues or patches related to the CK730 error.
  Costing Configuration: Review the configuration settings in the controlling (CO) module, particularly those related to product costing.
  
  By following these steps, you should be able to identify the root cause of the CK730 error and implement the necessary solutions to resolve it.
