Document Chains
When documents are created in ERP.net they usually form document chains.
For example, the basic document chain in CRM is:
Activity → Opportunity → Offer → Sales Order → Invoice Order → Invoice
The subsequent documents in the chain are usually automatically created, but can also be manually typed.
ERP.net tracks the relations between each document instance, so that the users can easily traverse the document chain up and down.

This feature can be especially useful for financials. Suppose you are investigating some financial statement. You open a Finance.Accounting.AccountingVouchers Entity:
From there you traverse up the document chain and consequently find Store Transaction, Receiving Order and finally the Purchase Order.
The saved navigation data helps you quickly spot the originating document:
