Rounding decimals in RF transaction (pick by WO)

[TT17]

Hi,

I created a Warehouse Order that I need to pick. For that i'm using the RF transaction.
The HU I need to pick has 3 decimals, the warehouse order that I created also has 3 decimals in it corresponds to the quantity of the HU.

When I pick the HU with the RF transaction and I'm on the confirmation screen it shows the correct quantity and 3 decimals but when I confirm this an error message pops up that I need to pick the quantity rounded up to 1 decimal. 

So for example:
HU: 389,524 kg
WO also shows: 389,524kg
Confirmation screen says: 389,524kg
After confirming error says: Pick 389,5kg

Anyone has an idea where to look for this?

Thank you.

Regards.

TT
