Technical Implementation Of Online Letter Display

Users can view an image of any letter that is sent to a customer if you plug plug-in an Online Letter Display algorithm on the Installation Record

Note: Some display algorithms rely on the extract algorithm on each letter template. Algorithms of this type format the records that contain the customer information that is passed to your printing software.

The system can make a call to an external system to retrieve a letter image. Many letter print vendors support this functionality.

The system provides an Installation – Online Letter Display algorithm type (C1GENLTTRURL) that can generate a dynamic URL.
  • The algorithm of this algorithm type supports dynamic variables such as the customer contact ID and static variable such a vendor or implementation supplied security key.
  • The algorithm constructs a URL including generating HASH or security keys.
  • The system displays the retrieved image in a separate browser session.
  • Refer to the algorithm type description for information about this algorithm type.

The system can interact with either document composition applications, or a reporting engine (such as BI Publisher).

The system provides an Installation – Online Letter Display algorithm type (C1-LT-DISP) that interacts with Documaker to render an online image of your letter. The following points describe what takes place when clicking Display Letter.
  • The algorithm based on this algorithm type calls the letter extract algorithm on each letter template.
  • The letter extract algorithm will construct the information that appears on the letter
  • The constructed information is passed to document composition software that will reconstruct the letter’s image in a PDF format.
  • The system displays the PDF in a separate browser session. Note that the client must have Adobe Acrobat Reader installed to view PDF files.
The system provides an algorithm that interacts with BI Publisher to render an online image of a letter. The following points describe what takes place when clicking Display Letter when these sample algorithms are used.
  • The sample Online Letter Display algorithm C1-ONLTR-RPT is executed.
  • This algorithm calls the letter extract algorithm. The sample letter extract algorithm C1-LTREX-RPT is supplied for displaying letters via BI Publisher. This is not actually extracting data because when you use BI Publisher, the report itself is responsible for extracting and formatting the data. The base product algorithm supplied returns the appropriate report code to the Online Letter Display algorithm, which in turn returns the report code to the customer contact page.
  • A user exit on the customer contact page invokes BI Publisher and displays the letter in a separate browser session.
