Extract date field from Taleo using TCC on basis of Requisition type

Hi Team,

I need to extract one field from TCC script on basis of requisition type.

If Requisition type is forecast then this field should return Business Required date in result file and if requisition type is confirmed then it should give Updated start date field data in result file.

Please help me with query to get this data using filter or any other option.

Thanks,

Vimal
