• What is the cause and solution for SAP error message /SAPAPO/SCC151 - Dimensions of units of measure differ (Evaluation not possible) ?

  The SAP error message /SAPAPO/SCC151 Dimensions of units of measure differ (Evaluation not possible) typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is a mismatch in the units of measure (UoM) being used in a planning scenario. This error indicates that the system is unable to perform a calculation or evaluation because the dimensions of the units of measure involved are not compatible.
  Cause:
  
  
  Mismatched Units of Measure: The most common cause of this error is that the units of measure for the quantities being evaluated are different and cannot be converted. For example, trying to compare or calculate values in kilograms and pounds without a proper conversion.
  
  
  Configuration Issues: There may be issues in the configuration of the units of measure in the system, such as incorrect settings in the master data or in the planning books.
  
  
  Data Inconsistencies: Inconsistencies in the master data, such as the units of measure defined for materials, can lead to this error.
  
  
  Solution:
  
  
  Check Units of Measure: Review the units of measure used in the relevant master data (e.g., material master, location master) and ensure that they are consistent. Make sure that the units of measure being used in the planning books or queries are compatible.
  
  
  Conversion Factors: If different units of measure are necessary, ensure that appropriate conversion factors are defined in the system. This allows the system to convert between different units of measure correctly.
  
  
  Review Planning Books: Check the configuration of the planning books and ensure that the key figures and characteristics are set up correctly with compatible units of measure.
  
  
  Data Consistency Check: Perform a consistency check on the master data to identify any discrepancies in the units of measure. This can often be done using transaction codes like MM02 for material master or CIF for integration checks.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling units of measure in APO.
  
  
  Testing: After making changes, test the scenario again to ensure that the error is resolved.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
