• What is the cause and solution for SAP error message MH020 - Specify a comparison price unit for the content unit ?

  The SAP error message MH020, "Specify a comparison price unit for the content unit," typically occurs in the context of materials management, particularly when dealing with the handling of materials that have different units of measure. This error indicates that the system requires a specification of a comparison price unit for the content unit of a material.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Missing Configuration: The material master record does not have a defined comparison price unit for the content unit. This is often the case when the material is set up with multiple units of measure, but the necessary relationships between these units are not properly configured.
  
  
  Incorrect Unit of Measure Settings: The unit of measure settings in the material master may not be correctly defined, leading to confusion in how the system calculates prices based on different units.
  
  
  Data Entry Errors: During the creation or modification of the material master, the user may have omitted to enter the required comparison price unit.
  
  
  Solution:
  To resolve the MH020 error, you can follow these steps:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM02 for change or MM03 for display).
  Navigate to the "Purchasing" or "Basic Data" views.
  Ensure that the "Base Unit of Measure" and "Alternative Units of Measure" are correctly defined.
  
  
  
  Define Comparison Price Unit:
  
  In the material master, ensure that the comparison price unit is specified for the content unit. This can usually be done in the "Purchasing" view under the "Unit of Measure" section.
  If the content unit is, for example, "liters" and the base unit is "pieces," you need to specify how many pieces are equivalent to one liter in terms of pricing.
  
  
  
  Check Unit of Measure Conversion:
  
  Ensure that the conversion factors between the different units of measure are correctly set up in the system. This can be done in the "Units of Measure" configuration.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct settings, refer to SAP documentation or consult with your SAP functional consultant for guidance on how to set up units of measure and pricing correctly.
  
  
  
  Testing:
  
  After making the necessary changes, test the material by attempting to create a purchase order or perform the action that previously triggered the error to ensure that it has been resolved.
