This error typically arises during data migration or conversion activities, particularly when using SAP's Conversion Tools or during the execution of a specific migration project.
  Cause:
  
  Missing Configuration: The object type (OBART) and object number (J_OBJNR) are not defined in the required tables CNV_20551_OBJ and CNV_20551_DERIV. This could happen if the necessary configuration or mapping for the data conversion has not been set up correctly.
  Data Inconsistency: There may be inconsistencies in the data being processed, leading to the system not being able to find the required definitions.

  Check Configuration: Verify that the object type (OBART) and object number (J_OBJNR) are correctly defined in the tables CNV_20551_OBJ and CNV_20551_DERIV. You can do this by:
  
  Accessing the relevant transaction codes (like SE11 or SE16) to view the contents of these tables.
  Ensuring that the necessary entries exist for the object type and number you are working with.
  
  
  
  Define Missing Entries: If the entries are missing, you may need to create them. This typically involves:
  
  Identifying the correct object type and number that should be defined.
  Adding the necessary entries to the tables using appropriate transaction codes or through a custom program.
  
  
  
  Review Migration Settings: Ensure that the migration settings and parameters are correctly configured. This includes checking any mapping or transformation rules that may affect the object types being processed.
