VbzCart/docs/queries/qryItms to restock

Details

• Returns: List of items where we need more of them, either to fill orders or to meet minimum stock levels. Accounts for restock items already requested and items currently in stock.
• Requires: Template:Vbzcart/query
• Used by:
• History:
  • 2008-11-18 created for new restocking process
  • 2008-11-19 added additional fields from revised union query
  • 2008-11-22 various quantities need to be SUMmed, else we got the wrong answer (probably just the first matching row)
• Notes: It might be a good diagnostic to run this query without the final "HAVING" clause (or with QtyToGet<0) and look for anything that doesn't make sense. Hopefully most of the negative numbers are overstocked items and unclosed restock requests (they should be closed).
