Vendor Posting Groups
GETTable: Vendor Posting Group
"Read-only vendor posting groups, and the payables control account each one posts to. The code is already published on the records that carry it; this is what the code means."
Why you need it
The posting group code appears on masters and documents throughout this API. What it does not tell you is which G/L accounts it directs postings to, and that mapping is the whole point of a posting group.
With this feed a report can tie a subledger balance back to the control account it posts to, and show the chart-of-accounts consequence of a master-data choice.
Reconciling payables
payablesAccount is the account vendor balances land in, and the same tie-out applies as for receivables: group vendorLedgerEntries by vendorPostingGroup and compare to the G/L.
