About
- Part of: catalog building process
Used by: qryCtg_Sources_active
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.
