• What is the cause and solution for SAP error message /CWM/MM101 - Stockkeeping/parallel units of measure &1/&2 and &3 are different ?

  The SAP error message /CWM/MM101 Stockkeeping/parallel units of measure &1/&2 and &3 are different typically occurs in the context of inventory management and material master data. This error indicates that there is a mismatch between the units of measure defined for a material in the system.
  Cause:
  
  
  Unit of Measure Configuration: The error arises when the stockkeeping unit of measure (UoM) for a material does not match the parallel unit of measure defined in the material master. For example, if a material is defined with a base unit of measure (e.g., pieces) and a parallel unit of measure (e.g., boxes), and there is a discrepancy in how these units are defined or used, this error can occur.
  
  
  Data Entry Errors: Incorrect data entry during the creation or modification of material master records can lead to inconsistencies in the units of measure.
  
  
  Material Master Settings: The settings in the material master for stockkeeping and parallel units of measure may not be aligned, leading to this error.
  
  
  Solution:
  
  
  Check Material Master Data: 
  
  Go to the material master record (transaction code MM03).
  Check the units of measure tab to ensure that the stockkeeping unit of measure and the parallel unit of measure are correctly defined and consistent.
  
  
  
  Adjust Units of Measure:
  
  If there is a mismatch, you may need to adjust the units of measure. This can be done by using transaction code MM02 to modify the material master record.
  Ensure that the conversion factors between the units of measure are correctly defined.
  
  
  
  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 Logistics > Material Management > Basic Settings > Units of Measure.
  
  
  
  Consult Documentation: 
  
  Refer to SAP documentation or help resources for specific guidance on handling units of measure and material master data.
  
  
  
  Testing: 
  
  After making changes, perform tests to ensure that the error does not reoccur when processing transactions related to the affected material.
