How To Fix CKBA312 - Mixing ratio of the valuation types is not 100 %

SAP Error Message - Details

• Message type: E = Error

• Message class: CKBA - Message Pool for Development Class CKBA

• Message number: 312

• Message text: Mixing ratio of the valuation types is not 100 %

What causes this issue?

For mixing ratio &V1&, it was specified in Customizing that the usage
probabilities should be maintained in percentages. Material &V2& has a
split valuation, and the mixing ratio is maintained for valuation
types. For this reason, the usage probabilities are maintained on two
levels: procurement alternatives and valuation types.
The total of the usage probability at the valuation type level is not
100 %.

System Response

The usage probabilities must total 100 %.

How to fix this error?

Either ensure that the total is 100 %, or use a mixing ratio that does
not require usage probabilities to be maintained in percentages.

• What is the cause and solution for SAP error message CKBA312 - Mixing ratio of the valuation types is not 100 % ?

  The SAP error message CKBA312, which states "Mixing ratio of the valuation types is not 100 %," typically occurs in the context of inventory valuation and cost accounting. This error indicates that the system has detected an inconsistency in the mixing ratios of different valuation types for a material. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Valuation Types: In SAP, materials can have multiple valuation types (e.g., standard price, moving average price). Each valuation type should have a defined mixing ratio that sums up to 100%.
  Incorrect Configuration: The mixing ratios for the valuation types may not have been configured correctly in the system.
  Data Entry Errors: There may be errors in the data entry for the mixing ratios, leading to a total that does not equal 100%.
  Material Master Issues: The material master data may not be set up correctly, particularly in the accounting view where valuation types are defined.
  
  Solution:
  
  
  Check Mixing Ratios: Go to the material master record and check the mixing ratios for the relevant valuation types. Ensure that the total mixing ratio equals 100%.
  
  Transaction Code: MM02 (Change Material)
  Navigate to the Accounting view and check the valuation types and their respective ratios.
  
  
  
  Adjust Ratios: If the ratios do not sum to 100%, adjust them accordingly. Ensure that the sum of all mixing ratios for the valuation types is exactly 100%.
  
  
  Review Configuration: If the issue persists, review the configuration settings for the valuation types in the system. This may involve checking the settings in the Customizing (SPRO) for Material Management and Cost Accounting.
  
  
  Consult Documentation: Refer to SAP documentation or help files for specific guidance on managing valuation types and mixing ratios.
  
  
  Test Changes: After making adjustments, perform a test transaction to ensure that the error no longer occurs.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM02 for changing material master data and CK11N for creating cost estimates.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Roles: Ensure that you have the necessary authorizations to make changes to material master data and configuration settings.
  Training: Consider training sessions or resources on SAP Material Management and Cost Accounting to better understand the implications of valuation types and mixing ratios.
  
  If the problem continues after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP MM (Material Management) and CO (Controlling) modules for further assistance.
