tax journal (Purchase transaction) missing supplier information

Hi,

I am creating a tax journal for the purpose of purchase transaction. I had populated the supplier name/site details/invoice information for which the tax journals were being passed. The tax journal has got created correctly, but it does not have any information of the supplier/site/invoice number etc on the journal. Can anyone please advise what might be missing here?

Regards,
