How can I setup a default text in automatic email ?

SOLVED

Hello Everybody!

How can I setup a default text in automatic email that I am sending a report from purchasing order?

I have created a workflow rule  to do this. I put a default text in : Setup>Workflow Rules>Message. But, It hasn't worked. When I am sending an report from purchasing order It shows me the same text awalys "Deve encontrar o anexo no estado " (in email body). I found this text  in a table: "APLSTD" but, I dont know how I can  change it.

I have attached screenshots.

Could someone help me with this case?

Thanks in advance
