To access QMOS in the PDA, you can either find it under the Reverse Logistics menu, or just type in QMOS under RF Apps and hit enter. It'll then ask you the location found (usually sales floor or backroom, try and be as accurate as you can), and then the reason why (out of temp, damaged, outdated). Then just scan (or you can enter the 4-digit PLU for produce only), enter in the quantity, hit Y or N to confirm the quantity or make a change, and then you're done! There are some things that have chargeback privileges that you have to defect out using SDEF, and a message will pop up saying that when you scan the item, but I usually just took those up to the service desk. Also, there are some things that when you go to scan them out, it'll say "enter a quantity in eaches from 6 to 99". I'm not sure why it does that or what it means (I notice it does that a lot for baking items), but I usually just took those to the service desk as well to have them defect out in there.
As far as opening, are you working in a Pfresh store acting as a PA that morning? This was my routine for weekend opens when we came in at 6a (and this was never very rigid as there is always something that comes up, but this was my general rundown):
6a-7a: Deep cull, write down DPCIs for TPCs
7a-8a: Process QMOS, then work ambient, produce, and meat autofills. I also made sure bananas were filled before the store opened just because it was our first impression the way our open market was set up. Then I'd go up to Food Ave and fill my sanitizer bottle right before the store opened, then first break at 8a (or after morning huddle).
8:20a - 10:30a: Complete SDA task lists, and QMOS outdates. Then work on cooler and freezer autofills (we don't have trucks on the weekends, so our flow TM isn't around to push those).
10:30a-11a: I took lunch at 11, so depending on how long it took to push the cooler and freezer autos, I'd use any downtime after that to enter my TPCs in the computer, random cleaning tasks, or fill milk and/or bananas again depending on time.
11:30a-2:30a: If it was a Saturday, which is an order day for us, I'd do the order first thing after lunch. If not and I wasn't able to fill milk before lunch, I would do that next. Then it's just working on CAFs and other little things until you clock out.
PAs are the first in line responsible for ordering, so if Sunday is an order day for your store, then yes, you would be the one placing the order. It's not too hard. Make sure you order bananas, and then you're just basically ordering any outs you have, and anything you're running low on and might run out of before your next delivery. When in doubt, find your CTL, or an LOD.
And then the biggest thing is just setting up your closer for a great evening. Stay on top of pulls, don't leave your QMOS or trash behind for the closer to take care of, keep bananas and milk relatively full, just things like that. I can't tell you how many times I came in to close on a weekend to morning autofills (which meant a packed metro rack of push) still sitting around at 2:30, bananas and/or milk are empty, opener left a cart full of cardboard behind. Granted, there was also a huge lack of accountability in my section, but it's very disheartening to walk in and already be way behind just 10 minutes in to your shift.
I probably just threw a lot of info at you, so if you have any more questions, ask away! There's a handful of current and former PAs here to help out 🙂
