Decimal weight accuracy Packaged Item

Hi community,

by creating Packaged Item's by integration in OTM in some cases we have the weight to an accuracy of three decimal places as can be seen in the detail of the following transmission:

the system correctly creates the object, but breaks the weight to only two decimal places:

The question then is: can it be done in such a way that the weight has a decimal precision of up to three decimal places? Should some property/ preference be set on the system?

Thanks.
