VbzCart/tables/cust charges

About

• Notes:
  • Batches are needed for batch-mode card processing. This was useful when credit cards were debited using PTC, which dialed in the charges using a modem (and hence you wanted to do as much offline as possible), but it's not necessary for PayPal. Will migrate later if it seems useful. Non-batch-mode charges can leave ID_Batch set to NULL.
  • I've decided that the field Resolved in the MS Access version should be a separate table listing unresolved charge records; this shouldn't be something that needs to happen when code is working properly.
• Fields:
  • AmtSold and AmtShip are necessary for PayPal Virtual Terminal, which wants to know these amounts separately. Presumably other card processing systems may also want this information.
  • AVSAuthChar: it's not clear whether any software besides PTC returns this code. It's also not clear what it means. Only Visa cards ever seem to return this code.
  • WhenDecided and isAccepted was WhenAuthorized and WhenRefused in Access
  • WhenHeldUp is specifically for old orders where the data which would complete the charge record is missing, and I don't want to fill it in with bogus data just to get it out of the queue. I can imagine that it might be useful for suspending charges due to technical difficulties, but I can't think of a scenario in which some other solution wouldn't be more appropriate. Still: set the timestamp in this field (and make a note!) if you need to pull a charge out of the queue without completing it.
