WmDB Converting Error Document List into String

I am new to webmethods. I am Using WMDB package with IS 4.6 to insert data. If the insert fails the error message is stored in $errors document list output variable for insert service. I Could not extract the error from this list to send a mail, If I map the document as attachment, the mail comes with null value. Any Easy way to convert the list to an string?.

Hello Rajan,
One of the ways is to Loop over the $errors and build the body of the mail and later send the mail.

Else, you can convert the $errors into a string directly by using the converttostring. For this you need to define a XML template of the record.
