Could be issues with upper/lower casepack shelves located incorrectly. Could also be your fulfillment team not caring. Assuming there are no other normal scheduled people who works in your backroom? You have to be efficient in pulling, organizing your pulls by aisle etc. When my etl or tl pulls one for one batches they will pile the cart a mile high with a literal overflowing mound of mess. But if I only pull one layer of items, push, pull another layer of items, I can complete my one for ones twice as fast since I’m not rummaging through nonsense on the floor.
Fix your sales floor quantities and capacities when you push truck. My etl would tell you to fix them for every box every truck, but that would require several hours. Instead, I try to check a handful of boxes for every vehicle I push. Consistency will lead to extremely good metrics. Right now my district’s new DC has royally fucked the truck situation up. For a week or two now dozens of items per truck will not have a delivery date, not be on hand(but it belongs to our store) etc after the truck is acknowledged. Can’t do much about that.
If your daily audits, drastic counts, check dates and subsequent defects, sales floor quantities, sales floor capacities, flex ties are all done correctly meaning proper # fit for the size shelf and you’re actively filling all possible locations when pushing, backroom locations are all accurate and properly set up, then it’s probably just fulfillment LOL
