Create Event Alert in Sales Order after Prepayment Process in R12

 Hi All,

Order to Cash Cycle 

·  Enter the Sales Order

·  Book the Sales Order

·  Launch Pick Release

·  Ship Confirm

·  Create Invoice

·  Create the Receipts 

·  Transfer to General Ledger

·  Journal Import

·  Posting

After the book sales order - say customer has made a prepayment @ that time --

Steps:

go to Actions -> Payments -> check Prepayment -> enter the other details -> process payment -> View Receipt ..

Now using the tables how i can check this pre-payment  is for the particular sales order.

Thanks
