• What is the cause and solution for SAP error message WTADDI418 - No class types maintained ?

  SAP Error Message:
  
  WTADDI418 No class types maintained
  
  Cause:
  This error occurs in SAP when you try to perform an action related to classification (such as assigning a class to an object, or using class types in a transaction), but the system does not find any class types maintained in the relevant customizing settings. Essentially, the system expects certain class types to be defined and available, but none have been maintained/configured.
  
  When does it typically occur?
  
  When working with Classification System in SAP (e.g., assigning classes to materials, equipment, functional locations, etc.).
  During configuration or usage of Object Types that require class types.
  When setting up or using WT (Work Time) or Time Management related classification.
  In some cases, during Personnel Administration or Organizational Management if classification is involved.
  
  
  Solution:
  
  
  Maintain Class Types in Customizing:
  
  
  Go to the SAP Customizing Implementation Guide (IMG):
  
  Transaction: SPRO
  Navigate to:
  
  Logistics - General ? Classification System ? Class Types ? Define Class Types
  
  
  
  Check if the required class types are maintained.
  
  
  If not, create/maintain the necessary class types relevant to your business process.
  
  
  
  
  Check Object Type Configuration:
  
  Ensure that the object types you are working with are linked to the correct class types.
  Sometimes, the error arises because the object type does not have any class types assigned or available.
  
  
  
  Check Authorization:
  
  Verify that the user has the necessary authorizations to view or maintain class types.
  
  
  
  Transport and System Consistency:
  
  If this error appears after a transport or system copy, verify that the customizing for class types has been transported correctly.
  
  
  
  
  Additional Information:
  
  Class Types define the category of classes in SAP Classification (e.g., 001 for Material Classes, 002 for Document Classes, etc.).
  Without class types, you cannot create or assign classes to objects.
  This error is a configuration issue, not a runtime or program error.
  If you are unsure which class types to maintain, consult your functional consultant or SAP documentation related to your module (e.g., MM, PM, HR).
