EDI document rejected by BizTalk

[ershad]

I’m trying to submit a EDI document to BizTalk but it is getting rejected
because of the following (error message as found in the Event Log):
The sender of the document is not recognized. Contact the system
administrator. (msgnr:0 segnr:0)(line:2 pos:1 filepos:362)sender: [][]
[9313938000631][ZZ][]sender: [][] [9313938000631][ZZ][]

Looking in the Parties folder in the BizTalk administration console I can
see that the following party has been created
EDI://9313938000631:ZZ:9313938000631

The EDI schema being used is EFACT_D01B_ORDERS.xsd and below is the message
being submitted to BizTalk.

No routing address is used in the UNB segment but it is specified in the
party: Try configuring it as 9313938000631:ZZ: (including the last colon).
