Request form parameters issues

 I have developed a custom report and i deployed it in E-business Suite in Payable responsibility

also i created many parameter for this report for example

 (organization_id , supplier_no , supplier_site_no,Date_info)

after that i designed LOV or value set for every parameter through the responsibility System Admin. in oracle EBS

1- What i need now is how to reference column in value set or LOV with the previous LOV

for instance :

the first LOV that retrieve the supplier_no as following :

   

  select VENDOR_ID,segment1,VENDOR_NAME  

                from ap_suppliers 

the second LOV that retrieve the supplier_site as following
