Analytics 10 Help, October 2013
Use WT.tx_i, WT.tx_id, and WT.tx_it parameters together. You must enable Visitor History in order to use the Invoice parameters.
Identifies the invoice number for the purchase. Webtrends Analytics 9 uses data stored in Visitor History to make sure that a page view with an invoice number is a new purchase and not the result of a visitor refreshing the page after making a purchase. If Webtrends Analytics 9 sees a page view with an invoice number, that page view is compared against the last three invoices for a visitor. If the WT.tx_i value does not match the last three invoices, Webtrends considers it a new purchase.
The Visitor Data Mart also recognizes this parameter. For more information, see Configuring Your Website to Collect Visitor Data Mart Data.
This parameter identifies the invoice number for the purchase. This value is used by the visitor history (in MLA) and by the eDBLoader (in MLW) to protect against a user hitting refresh after a purchase is made. This parameter is used to prevent the erroneous recording of purchases.
|Valid Value:||Alphanumeric string|
This parameter identifies the purchase invoice date (GMT-based) and is used to prevent the erroneous recording of purchases.
If the invoice date is three days older than the date of the visit, it is assumed that the hit is not an actual purchase but a view of a previously bookmarked or saved page. If the invoice date was less than three days than the date of the visit, the WT.tx_i parameter is used to determine if the hit is a valid purchase.
For example, a visitor makes a purchase. The purchase is accounted with an invoice date. The visitor saves a bookmark to the page. Five days later, the visitor goes to the bookmarked page. This causes another hit to be sent to SDC. However, the WT.tx_id parameter still contains the original purchase date. Webtrends analysis sees that the date of the hit is several days after the date found in the WT.tx_id parameter and determines that this is not an actual purchase.
|Valid Value:||Date. Both 2-digit and 4-digit years are recognized (mm/dd/yy or mm/dd/yyyy).|
This parameter identifies the purchase invoice time (GMT-based) and is used to prevent the erroneous recording of purchases.
This parameter helps determine when an invoiced purchase was made. This value is used along with WT.tx_id and WT.tx_i to determine if the purchase was a valid purchase or if this was a user refreshing the web page after a purchase or returning to the page to check status.
|Valid Value:||Time, in the format hh:mm:ss where “hh” is in 24-hour format (0=midnight, 23=11pm).|
