Integration points
Every module boundary a stream crosses is an interface. The ones marked straddle your scope — you are changing one side and not the other, which is the interface most often missed at scoping and found during testing.

Procure-to-Pay
One side of this is outside your scope
Supply Chain Management→Financial Accounting
Requisition-to-Receipt

Procurement
Nothing in scope blocks these — they can start together.
Accounts Payable
Unblocked once the phase above is standing.
Sequence is a delivery judgement rather than a fact about the taxonomy. These are proposals from common tier-1 ordering — argue with them.
