Diagnosis
The transfer already contains a target number for IDocs. The targetnumber is: &V1&
The current IDoc contains a different target number, that is: &V2&

Procedure
Check settings in the EDI subsystem. You can generally assume that allIDocs that are made up from one transfer number are correctlytransferred to the IDoc interface of the SAP system. The last IDoc madeup by the EDI subsystem should contain the total number of IDocs fortransfer in the segment/field E1EDS01-SUMME (SUMID = 028).
If this information is contained in several IDocs, then mapping must bechanged.
