Interface ITransactionProcessor

The main transaction processor for handling the core financial services engine processing of transactions within the system

See https://help.lemonedge.com/transactions/ for more information

This processor is responsible for calculating transaction, allocations, and gl entries according to the rules of the ITransactionCode and responding to UI events

Remarks

At its top level a transaction processor always deals with a root transaction entity.

Header transactions are top level transactions that all point to the root transaction (a header transaction itself)

Sub transactions are child transactions of a header transaction that contain detail at different entity levels along a path for the header transaction itself

All transactions, whether root, header or sub, are valid and can simply aggregated and reported on however they are required

Lastly a processor works with a root transaction, that stands alone by itself, or is part of a set with a (ParentItemID)
