When a letter is sent through snailmail and encounter an error, it used
to create an activity to the user to notify him that there was an error
with its letter.
When a user had this activity, he didn't have any clues of what was the
error and how to manage it. So we decided to better handle snailmail
errors and give the possibility to the user to easily fix the source of
the snailmail errors.
First to give a better feedback on the letters in errors, we've made
features similar to ones existing for emails:
- We add a mail message on the document that sent the letter, and put a
small paper plane icon, which is red when an error occurs (like the
envelope for email)
- As letters can be sent in batch, we've also added an entry in the
systray to easily manage the different documents having snailmail
errors like for emails.
Then we identified, the most common errors encountered with the
snailmail letters and give proper way to let the user fix them:
- Missing Required Field:
- The address is not complete, some of the fields are empty.
- We open a wizard allowing the user to modify the partner address
and we try to resend all letters having this error on the modified
partner.
- We also try to avoid this error, by opening the wizard before
sending the letter, but it only works for single documents, not
for batch.
- Trial/Credit Error:
- The user has not enough credits to send letters anymore.
- We open a wizard that give a redirection lnk to add credits on its
iap account.
- No Price Available:
- The destination country is not supported by any of our providers,
and we cannot do anything to send this letter.
- Format Error:
- The format of the pdf report send by the user is refused by our
providers, because some visual stuffs are not respected, for
example blank zone to print barcode or margins.
- We show a wizard to the user letting him check a setting option
that add a cover page in the envelope and the documents will be
send with this extra page containing the address.
- Unknown Error:
- This is not one of the listed error above.
- A wizard suggesting the user to contact support is displayed.
The cron that try to resend letters on error, has been addapted to only
try to send the error of type Trial/No Credit, because the account might
have been reloaded, and other errors, won't change if they have not been
fixed locally.
