you can try to import from file / Directory service/qlikview entity .
i've implemented with reference of below article using excel file source as recipient
also from AD
Thanks for reply, I have seen the first 2 links articles. And I also need to confirm one thing.
For the "delete old recipients" function, If I have 2 tasks, the source is from one excel, but different sheet.
If I checked the delete old recipients function for both tasks. will it delete other task's recipients? That's I'm afraid.
Because now I already have imported too many users into my NP from different sources, so I'm afraid it will delete all my users..
