Using KFF to query accounting rules

Question

Hi gurus,
We have a requirement to query some accounting rules based on code combination flex field values (which in turn should search by ccid).
I have a standard page which has a VO and it shows some 500+ records and literally there is no search functionality. Client wants a new search region with the ability to search with Accounting flex field values.
Users should be able to click on the flex field option and in the pop up window, they should be able to query a code combination and then that value should be used for query criteria when they click on a newly created 'Find' button. This submit action should append some query criteria to the existing standard VO and filter the records.
Can you give me some pointers on how to achieve this.
I am mainly looking for inputs on flex field.
I can able to create a separate region in mds and have added that as a personalization to the standard page and I can see the custom search region. Need to add KFF which is where I am stuck :)
Many Thanks
Vinod

Hi  Carol,
According to your description, my understanding is that  you want to pass values to an InfoPath  data connection (your  Web Service) using XPathNavigator .
For your issue, you need to get the innerxml of your data connection.Here is the code you can refer to:
String oProjectName = xformNav.innerxml;
wsNavigator.SelectSingleNode("/dfs:myFields/dfs:queryFields/ns7:Validate/ns7:projectName", NamespaceManager).SetTypedValue(oProjectName);
