• What is the cause and solution for SAP error message M5021 - Units are different - function will be performed w/o reference to units ?

  The SAP error message M5021, which states "Units are different - function will be performed without reference to units," typically occurs in the context of materials management and inventory management processes. This error indicates that there is a mismatch in the units of measure (UoM) between different components or data entries in a transaction.
  Cause:
  
  
  Unit of Measure Mismatch: The most common cause of this error is that the system is trying to perform an operation (like a goods movement, inventory adjustment, or order processing) where the units of measure for the materials involved do not match. For example, you might be trying to transfer a quantity in kilograms while the system expects it in grams.
  
  
  Configuration Issues: There may be issues with how the units of measure are configured in the material master or in the transaction itself.
  
  
  Data Entry Errors: Incorrect data entry during the transaction can lead to this error, such as entering a quantity in a different unit than what is expected.
  
  
  Solution:
  
  
  Check Units of Measure: Review the units of measure for the materials involved in the transaction. Ensure that they are consistent and compatible. You can do this by checking the material master data (transaction code MM03) for the relevant materials.
  
  
  Adjust Transaction Data: If you are entering data manually, ensure that you are using the correct units of measure. If necessary, convert the quantities to the expected unit of measure.
  
  
  Review Configuration: If the issue persists, check the configuration settings in the SAP system related to units of measure. This can include checking the settings in the material master, as well as any relevant customizing settings in the IMG (Implementation Guide).
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling units of measure in your version of SAP.
  
  
  Testing: After making adjustments, perform a test transaction to ensure that the error does not reoccur.
  
  
  Related Information:
  
  Material Master Data: The material master contains all the information about a material, including its units of measure. It is crucial to ensure that the data is accurate and consistent.
  Unit of Measure Configuration: In SAP, units of measure can be defined and configured in the system. This includes defining base units, alternative units, and conversion factors.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), MM02 (Change Material), and MIGO (Goods Movement) to troubleshoot and resolve issues related to materials and units of measure.
  
  If the problem continues after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in materials management.
