• What is the cause and solution for SAP error message /SAPAPO/SCC153 - & nondimensional unit (Conversion not possible) ?

  The SAP error message /SAPAPO/SCC153 typically relates to issues in the SAP Advanced Planning and Optimization (APO) module, particularly concerning the handling of units of measure (UoM) in the system. The specific error message "nondimensional unit (Conversion not possible)" indicates that there is a problem with converting units of measure, which can occur in various scenarios, such as during planning, data transfer, or when executing certain transactions.
  Cause:
  
  
  Unit of Measure Configuration: The error often arises when there is a mismatch or incorrect configuration of units of measure in the system. This can happen if the system is trying to convert between units that are not compatible or if the conversion factors are not defined correctly.
  
  
  Missing Conversion Factors: If the necessary conversion factors between different units of measure are not maintained in the system, SAP will not be able to perform the required conversions.
  
  
  Data Inconsistencies: Inconsistent or incorrect data entries in master data (like material master, location master, etc.) can lead to this error.
  
  
  Non-Dimensional Units: The error specifically mentions "nondimensional unit," which suggests that the system is encountering a unit that does not have a defined dimensionality, making conversion impossible.
  
  
  Solution:
  
  
  Check Unit of Measure Settings:
  
  Go to the relevant configuration settings in SAP and verify that the units of measure are correctly defined.
  Ensure that the conversion factors between different units are properly maintained.
  
  
  
  Maintain Conversion Factors:
  
  Use transaction codes like CUNI (Maintain Units of Measure) to check and maintain the conversion factors for the units involved in the error.
  
  
  
  Review Master Data:
  
  Check the material master and other relevant master data for any inconsistencies or incorrect entries related to units of measure.
  Ensure that the units of measure used in planning and execution are consistent and correctly defined.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific error message for any additional guidance or patches that may address the issue.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the error no longer occurs and that the system can handle the conversions as expected.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
