During your session, documents can be sent to you that are either displayed in a separate window or are processed by another program, depending on the document type. If you have ended your session before the documents are delivered, they are delivered when the next session begins.
You see this dialog box only if a server component has problems processing data.
Further problems with similar files may occur during data transfer; we therefore recommend that you inform your system administrator immediately and provide the information from the dialog for diagnosis and correction.
