Importing Purchase Data get wrong result

Hi, Expert,

I Have importing Purchase Order OPOR & POR1 data using DTW and it return success .

But when I Check the result I found that field Printed and Series was different with my data.

I was set Printed to N but it become Y in OPOR Table

I was set Series to 75 but it become -1 in OPOR table

Please give me advice what is wrong

Thanks
