Faxing MSDS via Reprt Shipping batch jobs

Hello guru's,

I am new to EHS and have a question about faxing MSDS's via report shipping automatically. We have the jobs running and the outputs are getting generated correctly for email, print and fax, but for the fax outputs when I look at SOST the recipient which should show the country code and then fax number shows the customer name instead.

Although we don't have a lot of fax records and are moving to email I would still like to understand why it would not use the fax number maintained on the SR or ship to party?

Any ideas where to look?
