About

Fields

  • ID_Supercede: Supplier Catalogs.ID of catalog which supercedes this one; NULL = this one is current
    • It can be set to point to the current record if the superceding catalog has not been entered or is not known.
  • isCloseOut:
    • TRUE = this catalog is a list of discontinued items no longer in print (closeouts)
    • FALSE = normal catalog; items will be marked as "in print"
  • WhenUpdated: When this record was last saved. This is actually significant for catalog building because it is copied to LCItem.Supp_LastUpdate. Presumably any time the record is edited, the editor would not leave the ID_Supercede field NULL if the catalog was not still current.
  • DateAvail: The approximate date of the catalog's effectiveness (e.g. "Spring 20xx" would be 20xx-03-15 or so, or date received if earlier)
  • DateExpires: The approximate date when the catalog is no longer expected to apply (e.g. "20xx Catalog" would be 20xx-12-31)

History

  • 2017-06-18 Changed engine from MYISAM to InnoDB; added LastUpdate
  • 2017-06-19 Added DateExpires

Notes

  • A "source" is usually a printed catalog from a supplier, though it can also be the manufacturer's web site on a particular date.
  • To discontinue a supplier, set ID_Supercede=ID for all active sources; the catalog will then show only current stock as available.
