Can you pleae let me know whether GWRW condition type is relevant for INTRASTAT reporting ?
GRWR is the value of the goods at the moment they cross the border, both during import and export (e.g. MM PO´s and SD sales orders).
GRWR condition-percentage depends on the incoterms like EXW, FOB, CIF etc. and based on that they will multiply the price by the GRWR condition-% (usually something like 97% to 100% varying form incoterm to another)
In intrastat reporting the GRWR value will automatically be picked up by the intrastat selection/reporting programs in SAP to report the border-crossing value (together with other intrastat data) to the authorities that receive the intrastat report, usually the countries customs- or tax-department.
