There is no EDIFACT D09B but you have only EDIFACT D09A in the wMEDI 6.5.2 module.
One more thing even in the WmEDI8.0.1 Module also I dont see EDIFACT D09B or A it has up to D08B ONLY…strange isn’t.
Since you are on wM6.5 and no SAG support you will get as it is EOS. So better you upgrade to IS 7.x/8.x versions and contact SAG on this schema issue:
