Web ADI: Ability to select LOV while using Query Content with Parameters

Hi Gurus,

As per current requirement when we use Oracle Web ADI Custom Integrator with content of SQL Query Which can allow to pass specific parameters while downloading data from application once data is download see those specific data and upload using same integrator.

Example : I want to find out for particular Asset which are retirement eligible for particular period or specific Asset , download using Custom Web ADI Integrator, review , upload after validating all values required to make asset retire. But Problem here for Data Range Parameters we could able select Date based calendar but for the optional Asset Number Parameter we are not able to select any Lov while downloading. Please see attached document which can explain more.
