Trending @Accenture; Priority in Workday

Imma recent joinee and have done around 1.5 months in current project. Recently been hearing a lot about setting priorities in Workday. (ie, from my batchmates, HR meets etc.)

Tried asking my AM (immediate supervisor) but they replied "We've not received any such details from the lead. You can ignore it".

So how important is it to fill this (as the deadline is near) and what exactly is it. If you're aware, please enlighten the fresher.

Thanks.
