Have you checked out the newly updated AR TroubleShooting Assistant (search helper) for the Receipts Workbench?
Troubleshooting assistants are a user-friendly way of searching the Oracle Knowledge Base based on the problem symptoms, and quickly identifying the appropriate documents to follow to resolve the error. They are a perfect tool for functional users to troubleshoot their problems, or for those users who may be reluctant to use the standard searching functionality. Many products in the E-Business Suite have produced troubleshooting assistants for specific areas of functionality, and all follow the same methodology.
The Receivables Receipts Workbench provides a collection of solutions that pertain to the symptoms you indicate.
For example, let's suppose you are having issues with applying/unapplying receipts. Simply display the troubleshooting assistant and check the functional area in which you are experiencing the problem within Receipts Workbench, as below:
Once you have identified the functional area, you then select the symptom(s) that most closely describes your issue. In the example below, you have noticed the following error message when you attempt to apply a receipt.

If you select a symptom that is closely related to another symptom, even if you haven't selected the related symptom, both symptoms are highlighted in blue to flag the relationship, and to give you the opportunity to further classify and validate your issue.
As you select each symptom, the document with the most appropriate solution is displayed in the 'Solution(s)' column. You then drill down on each of the displayed documents and review to find the answer to your issue.
Try it and see - it is really easy!
