VAT Posting Setup

GETTable: VAT Posting Setup

eOne/core/v1.0/vatPostingSetup

"Read-only VAT posting setup. Each row is the intersection of a VAT business posting group and a VAT product posting group, carrying the rate applied and the accounts VAT posts to."

The matrix

Both group codes are already published on customers, vendors, items and document lines. This is the table that turns a pair of codes into a percentage:

GET vatPostingSetup?$filter=vatBusPostingGroup eq 'EU' and vatProdPostingGroup eq 'VAT21'

Blank is a valid group

Business Central treats a blank VAT business or product posting group as a real group with its own setup row, usually the zero-rated one. Filtering it out as missing data removes exactly the rows that explain why something posted no VAT.

Not the same as vatEntries

This is the rate card. vatEntries is what was actually posted. Build a VAT return from the entries and use this to explain them.
