Hi villas thanks for your suggestion. I ran a test in the shell and it works:
web2py Web Framework Created by Massimo Di Pierro, Copyright 2007-2020 Version 2.20.4-stable+timestamp.2020.05.03.05.18.50 Database drivers available: sqlite3, pyodbc, imaplib, pymysql WARNING:web2py:import IPython error; use default python shell Python 3.7.8 (tags/v3.7.8:4b47a5b6ba, Jun 28 2020, 08:53:46) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

BTW, having DocNum=='350' makes no difference.
