Tracking for E-Mails 
Use
If you include links to Web sites in your E-mails, you can insert a tracking ID enabling you to monitor whether the recipient actually branches to the Web site. When the E-mail is sent, the tracking ID is replaced with a GUID identifying the business partner/campaign combination. When the business partner branches to the Web site, this GUID can be read and used, for example, to trigger information enabling the business partner to be greeted by name. In the case of SAP Internet Sales, this personal greeting is automatic.
Integration
The subsequent mailing list that can be called up for a given marketing campaign contains a counter as to how many times the business partner branched to the Web site from the E-mail. Note, however, that if an E-mail contains more than one link, there is no way of determining which link was used. For more information, see Mailing Lists.
Prerequisites
·
The internet address must
be indicated as such in the text editor by using the 
pushbutton. This also holds for HTML
E-mails.
· The tracking symbol "++" or “##” must be appended directly to the internet address, that is, without blanks.
With "++" tracking, you can directly track visits to your own site.
With "##" tracking, you can indirectly track visits to a foreign site from your site via a hidden redirect server page.
· The internet address must refer to a Web page from which a function module in the CRM System can be called up per remote function call (RFC). At this point, the Web page must transfer the identifier from the Web page to the function module CRM_IM_BP_DATA_GET_TO_MAIL. The identifier can be found after MIG=......
One way of calling up CRM_IM_BP_DATA_GET_TO_MAIL per RFC is by using the service ISAB2C in CRM Internet Sales. If, in transaction se80, you call up the Internet Service ISAB2C and view the template PORTAL_B2C, you can copy the point at which CRM_IM_BP_DATA_GET_TO_MAIL is called up (stored in the flow logic) and use it as a template for your own pages.
