routing data, and lot size) in the initital screen of the cost
estimate.

• What is the cause and solution for SAP error message CK738 - Quantity structure entries are ignored in a mixed cost estimate ?

  The SAP error message CK738 ("Quantity structure entries are ignored in a mixed cost estimate") typically occurs during the cost estimation process in SAP, particularly when dealing with mixed cost estimates. This error indicates that there are issues with the quantity structure entries that are not compatible with the mixed cost estimate being processed.
  Cause:
  
  Mixed Cost Estimate Configuration: The mixed cost estimate is designed to handle both variable and fixed costs. If the quantity structure (e.g., BOM, routing) does not align with the requirements for a mixed cost estimate, the system will ignore those entries.
  Inconsistent Quantity Structure: The quantity structure may have inconsistencies, such as missing components or incorrect quantities that do not match the expected format for a mixed cost estimate.
  Costing Variant Settings: The costing variant used for the mixed cost estimate may not be configured correctly to handle the quantity structure entries.
  Material Master Data: Issues with the material master data, such as missing or incorrect settings for costing views, can also lead to this error.
  
  Solution:
  
  Review Quantity Structure: Check the Bill of Materials (BOM) and routing for the material being costed. Ensure that all components are correctly defined and that the quantities are appropriate for a mixed cost estimate.
  Check Costing Variant: Verify the settings of the costing variant being used. Ensure that it is configured to handle mixed cost estimates and that all necessary parameters are set correctly.
  Material Master Data: Review the material master data for the materials involved in the cost estimate. Ensure that the costing views are properly maintained and that there are no missing entries.
  Use Standard Cost Estimate: If the mixed cost estimate is not necessary, consider using a standard cost estimate instead, which may not have the same restrictions regarding quantity structure entries.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on configuring mixed cost estimates and handling quantity structures.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CK11N (Create Cost Estimate with Quantity Structure) or CK40N (Change Cost Estimate) to analyze and adjust the cost estimates.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message or provide updates and patches.
  User Forums: Engage with SAP community forums or user groups to see if others have encountered similar issues and what solutions they have found effective.
  
  By following these steps, you should be able to identify the root cause of the CK738 error and implement the necessary changes to resolve it.
