1. What is 2-way, 3-way, 4-way matching? Can you give me an example of 2 way matching? [Complexity **]

2-way matching:2-way matching verifies that Purchase order and invoice quantities must match within your tolerances as follows:

Quantity billed <= Quantity OrderedInvoice price <= Purchase order price(<= sign is used because of tolerances)Often used for services where no receiver is generated.

3-way matching:3-way matching verifies that the receipt and invoice information match with the quantity tolerances defined:Quantity billed <= Quantity received

4-way matching:

4-way matching verifies that acceptance documents and invoice information match within the quantity tolerances defined:Quantity billed <= Quantity accepted.(Acceptance is done at the time of Inspecting goods).
