• What is the cause and solution for SAP error message /CWM/QM005 - Units of measure of material &1 and &2 must be the same ?

  The SAP error message /CWM/QM005 indicates that there is a mismatch in the units of measure (UoM) for two materials involved in a transaction or process. This error typically occurs in scenarios such as goods movements, inventory management, or quality management where two materials are being compared or processed together, and their units of measure do not match.
  Cause:
  
  Different Units of Measure: The most common cause is that the two materials have been defined with different units of measure in the material master. For example, one material might be in kilograms (kg) while the other is in grams (g).
  Configuration Issues: There may be configuration settings in the system that do not allow for conversion between the two units of measure.
  Data Entry Errors: Incorrect data entry during the creation or modification of material master records can lead to this issue.
  
  Solution:
  
  
  Check Material Master Records:
  
  Go to the material master records for both materials involved in the transaction.
  Verify the units of measure defined for each material. You can do this by using transaction code MM03 (Display Material) and checking the "Basic Data" and "Purchasing" views.
  
  
  
  Adjust Units of Measure:
  
  If the units of measure are indeed different and should be the same, you may need to change one of the materials to match the other. This can be done using transaction code MM02 (Change Material).
  Ensure that the conversion factors are correctly set up if you need to maintain different units of measure.
  
  
  
  Review Configuration:
  
  Check the configuration settings in the system related to units of measure. This can be done in the SPRO (SAP Project Reference Object) transaction under the relevant logistics area.
  Ensure that the system allows for conversions between the units of measure if necessary.
  
  
  
  Consult Documentation:
  
  Review any relevant documentation or guidelines provided by your organization regarding the handling of materials and units of measure.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test transaction to ensure that the error does not occur again.
  
  
  
  Related Information:
  
  Unit of Measure Types: SAP allows for different types of units of measure (base unit, alternative unit, etc.). Understanding these can help in configuring materials correctly.
  Conversion Factors: If you need to work with multiple units of measure, ensure that conversion factors are defined in the material master.
  Quality Management: If this error occurs in the context of quality management, ensure that the quality inspection plans and specifications are also aligned with the correct units of measure.
  
  By following these steps, you should be able to resolve the error message /CWM/QM005 and ensure that the units of measure for the materials involved are consistent.
