No, that doesn't look like IDocs. So the transmission of the IDocs must have been ok.
Can you select one of the IDocs in the target system in transaction WE05 and display the "Message" field of the last "Status Record"? Sometimes more error details as to what went wrong, can be seen here (or in one of the preceding status records). E.g. some problem in the ALE settings or a problem in the business application.
(Attached is an example of an IDoc that could not be posted, because the application layer (program SAPLVED4, subroutine BELEG_SPERREN) raised an error.)
