  Error Message
  WTADDI303: No internal class number exists for class type & and class &
  
  Cause
  This error occurs when the system tries to find an internal class number for a given class type and class, but it cannot find any entry in the classification system tables. In SAP, classes are stored with an internal class number (CLINT) which is used internally by the system to identify the class. If this internal number is missing or the class is not properly maintained, the system cannot proceed with classification-related operations.
  Typical scenarios causing this error:
  
  The class has been created but not properly saved or activated.
  The class type and class combination does not exist in the classification tables.
  Data inconsistency or missing entries in the classification tables (e.g., KLAH, KSSK).
  The class was deleted or corrupted.
  The system is trying to access a class that is not yet created or incorrectly referenced.
  
  
  Solution
  To resolve this error, follow these steps:
  
  
  Check the Class Existence:
  
  Use transaction CL02 or CL03 to check if the class with the specified class type and class name exists.
  If it does not exist, create the class using CL01.
  
  
  
  Verify Internal Class Number:
  
  The internal class number is stored in table KLAH (Class Header).
  Use SE16/SE16N to check if the class type and class name exist in KLAH.
  If missing, recreate or restore the class.
  
  
  
  Recreate or Repair the Class:
  
  If the class exists but the internal number is missing or corrupted, try to recreate the class or copy it from a working system.
  Sometimes, changing and saving the class again in CL02 can regenerate the internal number.
  
  
  
  Check for Transport or System Issues:
  
  If the class was transported from another system, verify that the transport was successful and all related objects were imported.
  Check for inconsistencies in the classification tables.
  
  
  
  Run Consistency Checks:
  
  Use report RCLACHECK to check the consistency of classification data.
  Fix any inconsistencies found.
  
  
  
  Consult SAP Notes:
  
  Search SAP Support Portal for notes related to WTADDI303 for any known bugs or patches.
