What Happens During Invoice Posting
During posting, these updates occur:
- 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.
