• What is the cause and solution for SAP error message KK748 - Mixed cost estimate in explosion level &1 for material &2 plant &3 ?

  The SAP error message KK748 indicates that there is a mixed cost estimate in the explosion level for a specific material in a particular plant. This error typically arises during the cost estimate process, particularly when dealing with materials that have different costing methods or when there are inconsistencies in the cost estimates.
  Cause:
  
  Mixed Costing: The error usually occurs when a material has been assigned different costing methods (e.g., standard costing and moving average costing) and the system is unable to reconcile these methods at the specified explosion level.
  Costing Variants: The costing variant used may not be set up correctly to handle mixed costs.
  Material Master Data: There may be inconsistencies or missing data in the material master records, such as the costing view or valuation class.
  Costing Run Configuration: The configuration for the costing run may not be set up to handle mixed cost estimates properly.
  
  Solution:
  
  Check Material Master: Review the material master data for the affected material. Ensure that the costing views are correctly maintained and that there are no inconsistencies in the valuation class or costing method.
  Review Costing Variant: Check the costing variant settings in the configuration. Ensure that it is set up to handle mixed costing if applicable.
  Costing Run Settings: Verify the settings for the costing run. Ensure that the parameters allow for mixed cost estimates if that is the intended approach.
  Recreate Cost Estimate: If necessary, try to recreate the cost estimate for the material. This may involve resetting the cost estimate and running it again to see if the error persists.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling mixed cost estimates and the relevant configuration settings.
