DTW error when import item master

Hi,

SAP Business One 9.0 (9.00.057) PL: 05

I try to import item master using DTW. I encountered error message "Sort Error-after map, please check the prepared data and delimeter".

I tried just 2 records also encountered the same error.

ItemCode ItemName ItemCode ItemName 321204060917 CAPRIFLOR PREMIUM BLUMENERDE 40 L 321207060917 CAPRIFLOR PREMIUM BLUMENERDE 40 L

I have no problem when import Chart of Accounts.

Thanks!
