  Cause:
  This error usually indicates that the system is unable to recognize or find the specified object reference type. This can happen due to several reasons:
  
  Missing or Incomplete Object Definition: The object you are trying to reference may not be defined in the system, or it may be incomplete.
  Transport Issues: If the object was recently transported from another system, it may not have been fully activated or may be missing dependencies.
  Authorization Issues: The user may not have the necessary authorizations to access the object.
  System Configuration: There may be inconsistencies in the system configuration or issues with the Data Dictionary itself.
  
  Solution:
  To resolve the DDIC_ADT_DDLS030 error, you can try the following steps:
