The Register table type contains a record of the range of transaction ID numbers for each batch of posted Ledger Entries. Register data provides an audit trail of the physical timing and sequence of postings. This, combined with the full details retained in the Ledger Entry, makes NAV a very auditable system, because we can see exactly what activity was done and when it was done:

The user views the Register through a tabular page, as shown in the previous screenshot. We see that each Register entry has the Creation Date, Source Code, Journal Batch Name, and the identifying Entry No. range for all the entries in that batch. Another NAV feature, the Navigate function, which we will discuss in detail in Chapter 4, Pages - the Interactive Interfaces, also provides a very useful auditing tool. The Navigate function allows the user (who may be a developer doing testing) to highlight a single Ledger entry and find all the other Ledger entries and related records that resulted from the posting that created that highlighted entry.
