Diagnosis
There are already several transfers to which the IDoc could be assigned.Only a maximum of one transfer should exist that is suitable forincluding the IDoc.
Suitable transfers are transfers that are not closed, that is, for whichthe processing step has not yet started or for which the target numberhas not yet been achieved.
The following internal transfers would come into question for the IDoc:

• V1


• V2


• V3


• V4

System Response
The verification step does not assign the IDoc to a transfer andinterrupts processing. The IDoc ends with status 51.

Procedure
Close the transfers, for example by starting the processing step so thatonly one transfer remains that can include the IDoc. You can process theIDoc again afterwards.
