• What is the cause and solution for SAP error message DDIC_ADT_DDLS404 - Dependencies cannot be calculated. Error while reading DDL metadata ?

  The SAP error message DDIC_ADT_DDLS404 indicates that there is an issue with reading the Data Definition Language (DDL) metadata, which is often related to dependencies in the Data Dictionary (DDIC). This error can occur in various scenarios, particularly when working with ABAP Development Tools (ADT) in Eclipse or when trying to generate or activate database objects.
  Causes:
  
  Inconsistent Data Dictionary: There may be inconsistencies in the Data Dictionary, such as missing or corrupted objects.
  Transport Issues: If objects were transported from one system to another, there might be dependencies that were not properly transported.
  Authorization Issues: The user may not have the necessary authorizations to read certain objects or metadata.
  Database Issues: There could be issues with the underlying database that prevent the system from reading the metadata correctly.
  System Configuration: Misconfigurations in the system or issues with the ABAP Development Tools setup can also lead to this error.
  
  Solutions:
  
  
  Check for Inconsistencies:
  
  Use transaction SE11 (Data Dictionary) to check for inconsistencies in the objects involved. You can also use transaction SE14 (Database Utility) to check and repair database objects.
  
  
  
  Transport Management:
  
  Ensure that all necessary objects have been transported correctly. Check the transport logs for any errors or warnings.
  
  
  
  Authorization Check:
