  Error Message
  WZ401 - Object type does not exist
  
  Cause
  This error occurs when the system tries to reference or use an object type that is not defined or does not exist in the SAP system. Object types in SAP are used to categorize and manage different business objects (e.g., material, customer, vendor, etc.) within various modules.
  Common scenarios causing this error include:
  
  The object type code being used is incorrect or misspelled.
  The object type has not been created or activated in the system.
  Custom object types have not been properly configured or transported.
  The program or transaction is referencing an object type that is not available in the current system/client.
  
  
  Solution
  To resolve the error, follow these steps:
  
  
  Verify the Object Type Code:
  
  Check the object type code being used in the transaction or program.
  Ensure it is correct and valid for the intended business object.
  
  
  
  Check Object Type Configuration:
  
  Use transaction SWO1 (Business Object Builder) to verify if the object type exists.
  Enter the object type name and check if it is active and properly defined.
  
  
  
  Create or Activate Object Type:
  
  If the object type does not exist, create it in SWO1 or import it via transport requests if it is a custom object.
  Activate the object type after creation.
  
  
  
  Check Transport Requests:
  
  If the object type is custom and missing, ensure that the relevant transport requests have been imported into the system.
  
  
  
  Check Program or Custom Code:
  
  If the error occurs in custom code, verify that the object type used in the code matches the existing object types.
  Correct any typos or incorrect references.
