Help regarding User Exit EXIT_SAPMP56T_001 - ZXTRVU01 for tcode PR05

Hi All,

Am using a user exit for the Tcode PR05 tcode. when we click the tcode PR05 and enter the PERNR, it shows all the trips relted to that pernr. But on the Currency column, it does not show that currency which is saved for the trip.How do i change the currency in the PR05 screen to my own. The exit for it is ZXTRVU01.
