Extending Letter Record Types

The following refers to logic supported by letter extract process C1-LTPEX – Letter Extract. Refer to The Letter Extract Processes for more information.

Each record type has a business object that defines the format and the logic to extract records of that type. The BO Extract Record plug-in spot contains the logic to populate the record's data area. This plug-in spot supports multiple algorithms. Each business object is delivered with one algorithm configured for this plug-in spot that contains the logic to populate the record type’s elements.

As described in Letter Data Area Organization, there is a detail data area that contains the individual elements for a record type. If your implementation wants to extend a delivered record type, define a custom data area that extends the detail data area. The organizing data area should not be extended. To populate the custom data area, create an additional algorithm for the Extract Record plug-in spot. The record’s schema is passed into the plug-in spot so subsequent algorithms have access to values defined by previous algorithms.
