Hi Jennifer,
You are welcome to the SCN.
Hi think I have the solution for your problem.
1 . Insert the new items that you have with DTW
2. Change your Item prices file and use the column LineNum instead of the column Pricelist. If you want to update the pricelist 4, in the linenum put 3.
3. Also very important is the separator on the step 4 of DTW
This works but test it in a test Database.
Hope it helps.
Regards,
Augusto
