What Happens During Invoice Posting
       The updates that occur during invoice posting are described
         here.
   
      - For each invoice, debit, or credit transaction posted, if the transaction 
	 is an invoice or a debit, the system increases: 
	- the customer's posted balance by the sum of the total transaction amount
- the customer's sales YTD and sales PTD values by the amount 
		 of the transaction. 
		If the transaction is a credit, the system decreases the customer's posted balance, sales YTD, and sales PTD in the same manner. 
 
- The customer's Last Invoice Date field is updated with the invoice date for the transactions.
- New open items are created, one for each transaction that is posted.
- Entries are created in the General Ledger A/R Distribution (AR Dist) Journal.
- For each transaction, one journal record is created for the Accounts Receivable amount, and one transaction is created for each distribution record entered.
