Bar Code scanning - Production Picking List Journal

I am looking to setup bar code scanning on production picking list, i.e. using a USB scanner to scan the labor hours and material as it passes by different operations during production. 

below setup has been made: 

1. Organisation Administration -> Setup -> Bar code setups

2. Assigned bar codes to an item under Product Information Management -> Manage Inventory -> Bar Codes.  

3. Finally create a moment order to test the item scanning and its working fine.

However when trying to scan the same item from Production Picking List its giving the below error. 

Any help would be appreciated to resolve the issue.

Regards,
