• What is the cause and solution for SAP error message SCM_MD_R3_PI026 - Alternative UoM &1 must not be defined as parallel UoM alternative ?

  The SAP error message SCM_MD_R3_PI026 indicates that there is an issue with the configuration of alternative units of measure (UoM) in the system. Specifically, it states that the alternative unit of measure (UoM) defined for a material must not be set as a parallel UoM alternative. 
  Cause:
  This error typically arises when:
  
  Incorrect Configuration: The alternative unit of measure for a material is incorrectly configured in the material master data. The system expects that certain units of measure should not be defined as parallel UoM alternatives.
  Data Inconsistency: There may be inconsistencies in the way units of measure are defined or used across different materials or in different contexts (e.g., purchasing, sales, inventory).
  Business Rules Violation: The business rules or settings in the system may dictate that certain units of measure cannot coexist as parallel alternatives.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Material Master Data:
  
  Go to the material master record for the affected material (transaction code MM03).
  Navigate to the "Basic Data" or "Purchasing" views and check the alternative units of measure defined for the material.
  Ensure that the alternative UoM is not set as a parallel UoM alternative if it is not supposed to be.
  
  
  
  Review UoM Configuration:
  
  Access the configuration settings for units of measure in the SAP system (transaction code OMN3).
  Verify the settings for the alternative UoM and ensure that they comply with the business rules and system requirements.
  
  
  
  Adjust UoM Settings:
  
  If the alternative UoM is incorrectly defined, you may need to remove it or change its configuration to align with the expected settings.
  If necessary, consult with your SAP functional consultant or system administrator to make the required changes.
  
  
  
  Test Changes:
