DELVRY03, Idoc is not updating with text

I am using DELVRY03 IDOC type for my inbound IDOC, I need to update Country of origin field in delivery data item level. Using message type SHPCON , there is a segment to hold this value E1EDL35-HERKL, but it is not updating this value in the delivery.

Appreciate your help.

Thanks,
