I cannot use TABLEUPDATE() since this is temporary cursor. I use this cursor to collect document rows.
For saving document, I use COPY TO and TABLEREVERT()

I added LOCK() command because without lock command, the same error occurs in REPLACE command. Using LOCK() I can output a friendly error message. However, error still occurs.
