Hi,
Yes, this should be possible and I think it would work quite well with the process you have today.
You can add a barcode to the paper Warehouse Pick list, using the Warehouse Pick No. or another unique reference. This would normally need a small customization to the pick list report.
The other part is Tasklet. You would need to check with Tasklet if the scanned value can be used to find or filter the Pick Order based on the Warehouse Pick No. This can depend on the Tasklet version and how its configured.
So basically the process would be:
Print Pick No. as a barcode → scan it in Tasklet → find the matching pick → start picking.
I would first check with Tasklet which field they recommend for this. Once thats confirmed, your BC partner/developer can add that field as a barcode on the pick list.
So yes, the BC side should be possible. The main thing to confirm is how Tasklet can use the scanned Pick No.
Thanks,
Sanket
