Creating Key flex values of Stock Locator from Custom OAF Page

Hi,

I have created one custom OAF page for doing subinventory transfer. For creating a stock locator, I have created the Flex item in my oaf page and assigned STOCK_LOCATOR KFF to that field. When am trying to create the new KFF combination from here, its creating without specific organization and subinventory, whereas i need to map the new locator to specific organization and subinventory which are selected by user in the page.

Kindly check and give me some solution.

Thanks
