VbzCart/tables/ord hold type

About

• Purpose: Admin-maintained table for different types of order-related events and how the order itself is affected by each event of that type
• Relates to: ord_event
• Background: See ord_event
• History:
  • 2008-12-27 Extracted from main "tables" listing, no design changes; no documentation yet, either
  • 2009-07-12 Removed isActive field; added "Hold" to field names for directional consistency (+1 always turns on an alert); preliminary documentation
  • 2009-10-18 changing type for alert flags from TINYINT to TINYINT(1); the default seems to be TINYINT(4)
    • BIT(2) would work, but there doesn't seem to be any clean way to represent -1
• Fields:
  • alert flags:
    • doHoldRstk - if TRUE, do not base restock requests on this order's items
    • doHoldChrg - if TRUE, do not make any debits from the customer for this order (wait for confirmation)
    • doContact - if TRUE, contact the customer before proceeding (do we need a separate "no payment" flag?)
    • doExamine - if TRUE, something about this order needs further examination (explanation in event notes)
    • It may be that we need a "doImport" flag, to indicate orders which need importing; doExamine is probably for more complicated issues which may take time/expertise to resolve. On the other hand, it may make more sense to detect un-imported orders in other ways, e.g. the fact that some fields will be NULL -- but it may be useful to have an explicit flag for this, e.g. to be able to signal that an order needs to be re-imported.

alert flags

The alert flag fields each have 3 possible values:

0 = no change

+1 = FORBID / TURN ON ALERT

-1 = ALLOW / TURN OFF ALERT

Each one affects the corresponding field in the order (not yet implemented as of 2009-07-12) as described above when an event of the type defined in this record occurs

If the order has any one of these flags set, then the order is "on hold".
