+      This table is a denormalized mix of all invoices and credit notes data.
+
+      It is built by creating a snowflake schema for the invoicing area and 
+      another one for the crediting area. In both cases, the cardinality is 
+      *:1 between line items and documents, and *:1 between documents and 
+      contacts. Then, the invoice and credit note side get unioned to be stored
+      in a single structure. The only transformation that happens differently 
+      across both is that credit note amounts get their sign reversed (* -1) so
+      that aggregations happen naturally (credit amounts subtract from invoice
+      amounts). The final granularity of the table is on the line item level.
+      Invoice and credit note records can be told apart through the 
+      document_class field.
+
+      The word _document_ in the context of this table encompasses both invoices
+      and credit notes.
+
+      The source of amounts is identifiable by their prefix. `line_` amount 
+      fields come from the line items data, while `header_` fields come from the
+      document level data. Aggregating line fields can be done without worries. 
+      Document level data can't be summed or averaged since it's duplicated per
+      line item, so be careful with it.
+
+      Most fields are not documented here: you can find more details in upstream 
+      models.
