Documentation

Definition

In the reference table, an external data module stores the references of the external data integrated into one document, if the type of external data integration is a referencing type. Such a table is required for every Reference module, as long as the contextual data of the edited document do not uniquely refer to the referencing data.

The reference table must be created when developing an external data module. It must have the following components:

the structure N2REFHDR or N2REFHDRXT
all key fields of the external data to be referenced.

N2REFHDR is required for exteral data modules that supply simple documentation elements and simple structures, and N2REFHDRXT is required for such external data modules that supply multiple structures. These have the following components:

Client (MANDT)

Key (code) of the referencing document (REFDOK)

Reference key (REFKEY)

Sequential number of the reference (LFDNRREF)

Line reference (LINEREF) (only N2REFHDRXT)

It is a standard for references to parameterized documents to be stored in the table N2DOKREF.
