• What is the cause and solution for SAP error message DDIC_ADT_DDLS091 - No AST could be generated ?

  The SAP error message DDIC_ADT_DDLS091: No AST could be generated typically occurs in the context of the ABAP Development Tools (ADT) when there is an issue with the generation of the Abstract Syntax Tree (AST) for a data definition or structure. This can happen for various reasons, including issues with the underlying data model, syntax errors, or inconsistencies in the data dictionary.
  Causes:
  
  Syntax Errors: There may be syntax errors in the ABAP code or data definitions that prevent the AST from being generated.
  Inconsistent Data Dictionary Objects: If there are inconsistencies or issues with the data dictionary objects (like tables, views, or types), it can lead to this error.
  Missing Dependencies: If the data structure relies on other objects that are missing or not activated, it can cause this error.
  Transport Issues: If the object was transported from another system and not properly activated, it may lead to this error.
  Version Compatibility: Sometimes, the version of the ADT or the underlying SAP system may not be compatible, leading to issues in generating the AST.
  
  Solutions:
  
  Check Syntax: Review the ABAP code or data definitions for any syntax errors. Use the ABAP editor to check for errors and correct them.
  Activate Objects: Ensure that all related data dictionary objects are activated. You can do this by navigating to the relevant objects in the Data Dictionary (SE11) and activating them.
  Check Dependencies: Verify that all dependencies for the data structure are present and activated. This includes checking for any missing tables, views, or types.
  Transport Management: If the object was transported, ensure that all related objects were also transported and activated in the target system.
  Clear Cache: Sometimes, clearing the cache of the ADT or restarting the ADT can resolve temporary issues.
  Update ADT: Ensure that you are using the latest version of the ABAP Development Tools. If not, consider updating to the latest version.
  Check System Logs: Review the system logs (transaction SLG1) for any additional error messages or warnings that may provide more context about the issue.
