Inside the 820
Three segments to know
BPR
The total payment amount, method, and banking detail.
RMR
Maps each invoice being paid to what was applied against it.
ADX
The deduction itself: a reason code and an amount.

That reason code is what you're hunting for →
Reading the code
The code is a category, not an explanation
A shortage code and a pricing code look identical on the line: a number and a dollar amount.
Each family calls for different evidence: proof of what shipped, versus proof of what price was agreed.
Read the family wrong, and you pull the wrong document first.

Deduction families
Six cause families
Shortage
Received quantity was less than invoiced.
Pricing
Invoice price didn't match the PO.
ASN/EDI
The 856 was late, missing, or wrong.
Compliance/OTIF
Delivery missed the window.
Freight & Quality
Routing requirement or spec missed.

Which lines are worth pursuing? →
Deciding what to dispute
Two signals, not one
Frequency
One or two of the same code in a cycle is usually a one-off, worth a quick dispute.
The same code every cycle is a process problem, not a fluke.
Materiality
A $40 deduction often costs more in staff time to fight than it returns.
The same pattern repeated 200 times a quarter is a five-figure number.

What happens after you file →
After you file
Two deadlines nobody mentions
A draft dispute you don't submit expires automatically after 14 days.
A case marked "Supplier Action" auto-closes if you don't respond within 7 days.
Neither is the claim's actual dispute window. That's separate, and it varies by code.
