Price list update by DTW

Hello

i checked 903392 - DTW_How to set PriceList field for the Items_Price object

1. I created template file

2. I want update this price list

3. Mapping rules (pricelist should be blank but i tried also when value was in)

4. Import 0 errors but price is still OLD. Data import from excel work corectly but here i cant control erros , i have over 1k indexes to import. Any advices?
