You can if the item has a backroom location, but that's not best practice to use it to psych out sales accumulator. The better way would be to use the fill from stockroom feature and do a "fill" for all the locations. If you enter the capacity or greater for each location it will decrease the sales accumulator to 0 and not put a pull in.
As a preview we are working on some new replenishment changes that should help alleviate some of the floor replenishment issues, such as being able to edit capacities for locations. Also the way I suggested above as a best practice does require the item to be in the backroom which I realize could be troublesome in a few scenarios, we are also looking at ways to address this in our changes.
And just so we better understand the issue, is it that you are calling a store on behalf of a guest who wants an item your store doesn't have in stock and you are wanting the store to set it aside for the guest? And since the TM you called doesn't have a device you want to be able to assist them in quickly finding the item without them having to get a device?
As for the backroom, I'd imagine the use case would be being able to tell the other TM that they have some in the backroom so the TM could grab a device, find it back there and then TAKE it from the back? Backroom location wouldn't be all that helpful, right?
It'll be called "on the way" on MyDevice, so it'll appear in that same section, just now with the date included with the quantity!
