Three Accounting Layers
Accounting layers provide different ways of segregating transactions within a single GL account to satisfy reporting requirements. The posting of transactions is controlled by associating daybook types with one of the three system-defined accounting layers: primary (labelled official in the system), secondary (labelled management in the system), and transient.
The primary layer is used for daily transaction posting.
Define one or more secondary layers to allow for adjustments required to meet different GAAP or IFRS requirements, or for management reporting.
The transient layer is used to temporarily post transactions pending approval, or to simulate postings.
GL entries can be moved from layer to layer by changing the daybook. You can use Mass Layer Transfer to change many transactions at one time. In reporting, multiple layers can be selected.
