Receipt API's in Oracle APPS R12

Receipt API in Oracle Receivables

Autolock box provides a functionality to create receipts using interface method. Recent versions of oracle applications, especially 11.5 onwards, Receipt API is getting used as they are flexible to the user’s need, and customization across all kinds of interfaces, loading.
Here are the receipt APIs used in 11i applications:

ar_receipt_api_pub.Create_cash
ar_receipt_api_pub.Apply
ar_receipt_api_pub.Unapply
ar_receipt_api_pub.Reverse
ar_receipt_api_pub.Apply_on_account
ar_receipt_api_pub.Unapply_on_account
ar_receipt_api_pub.Activity_application
ar_receipt_api_pub.Activity_unapplication
ar_receipt_api_pub.Apply_other_account
ar_receipt_api_pub.Unapply_other_account
ar_receipt_api_pub.create_misc
ar_receipt_api_pub.set_profile_for_testing
ar_receipt_api_pub.Apply_Open_Receipt
ar_receipt_api_pub.Unapply_Open_Receipt

I already have added sample script for receipt creation and application in earlier post.
