• What is the cause and solution for SAP error message CLMM078 - Object &, characteristic &: value "&" is already set ?

  The SAP error message CLMM078 indicates that there is an attempt to set a characteristic value for an object that has already been assigned that value. This typically occurs in the context of classification in SAP, where characteristics are used to define the properties of objects (like materials, equipment, etc.).
  Cause:
  The error occurs when:
  
  You are trying to assign a characteristic value to an object that already has that value assigned.
  There may be a logic error in the program or transaction you are using, where it attempts to set a value that is redundant.
  The characteristic is defined as unique for that object, meaning it cannot have the same value assigned multiple times.
  
  Solution:
  To resolve the CLMM078 error, you can take the following steps:
  
  
  Check Existing Values: 
  
  Go to the classification data of the object in question and check the current values assigned to the characteristic. You can do this using transaction codes like CL03 (Display Class) or CL02 (Change Class).
  
  
  
  Modify the Assignment:
  
  If the characteristic value is already set and you need to change it, you will need to first delete the existing assignment before setting a new value. This can be done in the classification view of the object.
  
  
  
  Review the Logic:
  
  If this error is occurring in a custom program or transaction, review the logic to ensure that it does not attempt to set the same value multiple times unnecessarily.
  
  
  
  Consult Documentation:
  
  Check the SAP documentation or help files related to classification and characteristics for any specific rules or constraints that may apply to your scenario.

  User Exits and BAdIs: If you are working with custom developments, check if there are any user exits or BAdIs that might be influencing the behavior of characteristic assignments.
