  The SAP error message /CWM/MM100 Stock keeping units of measure &1 and &2 are different typically occurs in the context of inventory management or material management when there is a mismatch between the units of measure (UoM) for stock keeping units (SKUs) in a transaction or process.

  Cause:
  
  Different Units of Measure: The error indicates that the system is trying to process items that have different units of measure. For example, if you are trying to move stock from one location to another, and the stock is measured in different units (e.g., pieces vs. boxes), the system will raise this error.
  Configuration Issues: There may be a configuration issue in the material master data where the base unit of measure and the stock keeping unit are not aligned.
  Data Entry Errors: Incorrect data entry during transactions can lead to this error, especially if the user selects the wrong unit of measure.
  
  Solution:
  
  Check Material Master Data: Verify the material master data for the items involved in the transaction. Ensure that the units of measure are correctly defined and consistent. You can do this by using transaction code MM03 to display the material master and check the units of measure.
  Adjust Transaction Data: If you are entering data manually, ensure that you are using the correct unit of measure for the transaction. If you are moving stock, make sure that the source and destination stocks are in the same unit of measure.
  Convert Units of Measure: If necessary, convert the units of measure to match. This may involve adjusting the quantities or using a conversion factor if applicable.
  Review Configuration: If the issue persists, review the configuration settings in the SAP system related to units of measure. This may involve checking the settings in the customizing transaction SPRO under Material Management.
