PO Creation of free goods for intrastat reporting

All,

Due to intrastat reporting restrictions, when we are creating a PO with a free good we need to mark the item as "Free Good" on the item overview, and set the "Business Transaction type" to 41 on the "Origin / Destination / Business" tab of the "Import" tab.

However, we also need to set the "Statistical value" on the "Decleration Values" tab but this field is greyed out.

The help message says:

The system determines statistical values on the basis of condition records with condition types GRWR and GWLB (subcontracting).

However it does not say where I can set this value. Does anyone know where I can set this value per material?

Many Thanks,

Colm
