Synchronise Update Handling

The Sales Order and Purchase Order imports support Synchronise update (differential) handling.

Acumatica does not return any intrinsic child/line ids when creating a transaction so you need to designate which field is used for the differential update.

The value which is mapped to UpdateComparisonField dictates the field - this field then maintains the unique (external) value assigned to each line.

Each existing line is then compared with a line in the IMan data, yielding the differential update.
