VbzCart/procs/Upd Titles fr TitleIttyps

About

• Purpose: Updates some fields in _titles
• Input: qryCat_Titles_Item_stats, grouped by ID_Title
• Output: _titles (update)
• History:
  • 2010-11-10
    • Added DROP PROCEDURE for easier maintenance.
    • Created in database (procs were not ported from L48 to Rizzo).
  • 2011-12-24 this was in a recursive loop: this→_titles→Upd_TitleIttyps_fr_Titles→_title_ittyps→this, so changed source from _title_ittyps to qryCat_Titles_Item_stats.
