How to create custom WebADI LOV that returning values to multiple columns

Dear Experts,

I am on R12 and created an WebADI with following columns (by desktop integration manager):

SUPPLIER_NUM, SUPPLIER_NAME

I have created a table validated LOV on SUPPLIER_NUM. The LOV will display SUPPLIER_NUM & SUPPLIER_NAME. User can choose the value and the SUPPLIER_NUM can be populated into the Excel ADI supplier number column.

I would like both SUPPLIER_NUM & SUPPLER_NAME columns being populated at the same time when user select the value on the LOV. Anyone know how can it be achieved.

Below is my current setup:

COMPONENT:

table-column-alias: SUPPLIER_NUM, SUPPLIER_NAME

table-column: SUPPLIER_NUM, SUPPLIER_NAME
