Cannot find either column "dbo" while generating view in SQL

Why each time I run this SQL code it always generates an error:

Msg 4121, Level 16, State 1, Procedure view_last_documents, Line 38 [Batch Start Line 9] Cannot find either column "dbo" or the user-defined function or aggregate "dbo.get_doc_owner", or the name is ambiguous.
