Mapping to two display fields for supplier table

Dear Experts,

I have want to show supplier ID and supplier name on UI screen so I’m made both the fields in supplier table as display fields and it worked.

But when I did this, the data (info record) is not passing and it is falling due structural exception.

The reason is source supplier ID is not able to map with destination supplier ID as there are two display fields

So my requirement is how to map source supplier ID to destination supplier table (supplier ID and Supplier name).
