A Customer Posting Group is used to define which accounts receivable general ledger account to use when selling goods to a Customer.
Customer Posting Groups are maintained using the Customer Posting Groups page.
I used search to navigate to the Customer page. I used + New to create a new Customer

I reviewed the Invoicing tab for the new Customer
I clicked the + New link
I added code DOMESTIC and set Receivables Account to 15110 (Account Receivable, Domestic)
Customer Posting Group is set to DOMESTIC
I used search to navigate to the General Journal page
I selected Customer Alpine Ski House
I clicked the Preview Posting button
The preview showed 8 General Ledger entries, 1 Customer Ledger entry and 1 Detailed Customer Ledger entry
The first general ledger entry relates to General Ledger account 15110 Accounts Receivable, Domestic (per the DOMESTIC Customer Posting Group).
