Invantive Studio shows these messages in common situations. The meaning and the way forward of each: - "Insert is not allowed." or "Update is not allowed.": the user lacks the right to change this kind of row, or the folder does not take new rows. See [[Invantive Studio/Repository/Concepts/Function Rights|Function Rights]]. - "You can not delete a list.": "Delete" was chosen on a folder; select a row instead. - "Are you sure you want to delete this item?": confirmation before a row is deleted. - "There are unsaved changes. Do you want to save them?": the main window is being closed while rows have not been saved. - "To show common properties all selected objects must be of the same type. Choose only objects of the same type!": nodes of different kinds were ticked in the tree. - "Can not navigate from node '...'.": "Go to Definition" was chosen on a node that does not refer to another row. - "Preview of data not available.": the data preview of a table or business object could not be read, for instance because the business object is not generated yet. - "This application runs only on the database platform 'Oracle RDBMS'.
