Posting Document not created (export data missing)

We are working on ECC 6.0 and during creation of Cancellation Billing document type IVS for the Intercompany billing, the document did not create Accounting document giving the Posting status as G - Posting document not created (export data missing). However checked the Foreign trade data and the system states that Foreign trade is complete.

Can any one suggest the solution for this?

Thanks.
