• What is the cause and solution for SAP error message C5620 - You cannot convert the charge quantity unit to the material quantity unit ?

  The SAP error message C5620, "You cannot convert the charge quantity unit to the material quantity unit," typically occurs in the context of materials management or production processes when there is a mismatch between the units of measure for a charge quantity and a material quantity. This can happen in various scenarios, such as during the creation of production orders, goods movements, or when dealing with batch management.
  Cause:
  
  
  Unit of Measure (UoM) Configuration: The charge quantity and material quantity may be defined with different units of measure that are not compatible for conversion. For example, if the charge quantity is in liters and the material quantity is in kilograms, SAP may not be able to convert between these units without a defined conversion factor.
  
  
  Missing Conversion Factors: There may be no conversion factors defined in the material master for the specific units of measure involved. SAP requires these factors to perform conversions between different units.
  
  
  Incorrect Material Master Data: The material master data may not be set up correctly, leading to inconsistencies in how units of measure are defined and used.
  
  
  Batch Management Issues: If batch management is enabled, there may be issues with how batches are defined in terms of their units of measure.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master (transaction code MM03) and check the units of measure defined for the material in question.
  Ensure that the charge quantity and material quantity have compatible units of measure.
  
  
  
  Define Conversion Factors:
  
  If the units of measure are different, you may need to define conversion factors in the material master. This can be done in the "Units of Measure" view of the material master.
  Ensure that the conversion factors are correctly set up to allow for conversions between the charge quantity and material quantity.
  
  
  
  Review Configuration Settings:
  
  Check the configuration settings in the SAP system related to units of measure. This can be done in the customizing settings (transaction code SPRO) under Logistics > General > Master Data > Units of Measure.
  Ensure that the necessary settings for unit conversions are in place.
  
  
  
  Batch Management:
  
  If batch management is involved, ensure that the batches are defined with the correct units of measure and that they are compatible with the material quantities being processed.
  
  
  
  Testing:
  
  After making the necessary changes, test the process again to see if the error persists. If it does, further investigation may be needed to identify any other underlying issues.
