Typically, a failed send will be flagged in the message control table (NAST), and this table should be monitored closely. However, there are many reasons why a document hasn't gone through, and this can be the case with both outgoing faxes and e-mails from SAP. The solution to both is the same: After identifying the failed document, re-send it manually by going inside it in change mode and repeating the appropriate output. If an obsolete customer e-mail address was the culprit, a customer master change would also be required, along with an audit of any docs recently created for this customer.
If any underlying data has changed since initial issuance, a re-sent document may not appear identical to the (failed) original. Sometimes, as when address info has been corrected, this can be a good thing. After all, the new document is more accurate than the old one.
In other cases, such as when pricing info has changed, it might be a cause for serious concern. There are several ways to deal with this concern:
1) Limit the types of changes allowed on certain docs after creation
2) Set up a doc image archive via ArchiveLink and re-issue output from there instead of from the current doc; or
3) For highly sensitive docs, consider a more secure delivery method.
