Hi,
Posting groups in NAV links between Customers/vendors and Products financials to the General Ledger. For Sales and Purchases there are three types of posting groups.
1. General
2. Specific
3. Tax/VAT related
General Posting groups are used to post the sales and purchases to the General Ledger. (Income Statement or P/L accounts)
Specific Posting groups are used to post to the Receivables and Payables accounts (Balance Sheet Accounts)
VAT posting groups are used to post to the VAT accounts.
To access General posting groups setup you can search General Posting Setup and that matrix will show which G/L accounts will be used based on groups.
To access specific posting groups you can search Customer Posting Groups and Vendor Posting Groups.
