• What is the cause and solution for SAP error message CM_EHPRC_COD_COMMON001 - Substance &1 already assigned; select another substance ?

  The SAP error message CM_EHPRC_COD_COMMON001 indicates that the substance you are trying to assign or use in a particular context is already assigned to another entity or process within the system. This is a common issue in SAP's Environment, Health, and Safety (EHS) module, particularly when dealing with substance management.
  Cause:
  
  Duplicate Assignment: The substance you are trying to assign is already linked to another object, such as a product, material, or another substance.
  Data Integrity Rules: SAP enforces data integrity rules to prevent the same substance from being assigned to multiple entities simultaneously, which can lead to inconsistencies in data management.
  Configuration Issues: There may be configuration settings in the EHS module that restrict the assignment of substances.
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Use transaction codes like C223 (for checking substance assignments) or C201 (for checking material assignments) to see where the substance is currently assigned.
  Review the substance's details in the Substance Management area to identify its current associations.
  
  
  
  Select a Different Substance: If the substance is indeed already assigned and cannot be reassigned, you will need to select a different substance that is not currently in use.
