How To Fix KK749 - Mixed cost estimate exists: maximum of &1 explosion level(s) possible

SAP Error Message - Details

• Message type: E = Error

• Message class: KK -

• Message number: 749

• Message text: Mixed cost estimate exists: maximum of &1 explosion level(s) possible

What causes this issue?

The material cost estimate is to be exploded for one or more mixed cost
estimates. However, material explosion does not support the explosion
of mixed cost estimates.

System Response

The explosion of the material cost estimate is terminated.

How to fix this error?

The material cost estimate can only be exploded up to explosion level
&v1&. Restrict the explosion to no more than &v1& level(s).

Procedure for System Administrators

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

• What is the cause and solution for SAP error message KK749 - Mixed cost estimate exists: maximum of &1 explosion level(s) possible ?

  The SAP error message KK749, which states "Mixed cost estimate exists: maximum of &1 explosion level(s) possible," typically occurs in the context of cost estimating in SAP, particularly when dealing with mixed cost estimates in the Controlling (CO) module. This error indicates that the system has encountered a mixed cost estimate that exceeds the allowed number of explosion levels.
  Cause:
  
  Mixed Cost Estimate: The error arises when a mixed cost estimate (which includes both variable and fixed costs) is being processed, and the number of levels of detail (explosion levels) in the cost estimate exceeds the maximum limit set in the system.
  Configuration Settings: The maximum number of explosion levels is defined in the system configuration. If the cost estimate requires more levels than allowed, this error will be triggered.
  Complexity of the Cost Structure: If the cost structure of the product or service being estimated is too complex, it may lead to a situation where the number of explosion levels exceeds the configured limit.
  
  Solution:
  
  Check Configuration: Review the configuration settings for cost estimates in the SAP system. You may need to adjust the maximum number of explosion levels allowed. This can typically be done in the configuration settings under the Controlling module.
  
  Transaction Code: SPRO (SAP Project Reference Object)
  Navigate to: Controlling -> Product Cost Controlling -> Cost Object Controlling -> Define Maximum Explosion Levels
  
  
  Simplify Cost Structure: If possible, simplify the cost structure of the product or service. This may involve reducing the number of components or levels in the cost estimate.
  Review Cost Estimate: Analyze the specific cost estimate that is causing the error. Check if there are unnecessary components or if the structure can be optimized.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on handling mixed cost estimates and explosion levels.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Cost Estimate) and CK40N (Change Cost Estimate) to manage cost estimates effectively.
  SAP Notes: Check for any SAP Notes related to this error message for additional insights or patches that may address the issue.
  User Roles: Ensure that you have the appropriate authorizations to make changes to cost estimate configurations.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP Controlling for further assistance.
