Hi Jana,
Until the version 10.0.25, there is no way to reprint a label from it’s item id. If I’m understanding well, the workers are struggling with LPs when they want to perform a picking work.
First you can create a mobile device menu item Action code =”movement by template” and then insert a print instruction int the work template

Work template:

Second : There is a new feature you can take a huge advantage from without reprinting the labels.
Here is scenario that can be useful in your case:
picking work With selection of the LP from a list

After opening the work you want to execute, click on the new button “Location inquiry”
It opens a location inquiry form with the picking location of the work then click on ok
It opens the list of LPs within the location. Click on LP card
The app goes back to the picking work and brings the LP Number
Create an App Detours

- Create a mobile device step for this menu item under (Warehouse management> Setup > Mobile device >Mobile device step)
- Create an app Detour for the mobile device step
- Add a step confirmation
- Go to available detours (menu items) Fast Tab and select an available select “Location Inquiry”
- Click on select field to send
- send to detour the location
- Send back after detour LP
N.B : In order to use this feature you need to activate those features in the feature management workspace
In this order

- Warehouse app step instructions
- Warehouse management app detours
