Email text generated by RSPPFPROCESS

Via RSPPFPROCESS we can generate emails containing PDF attachments of PO's recently created.

The email that is generated, however, has an abbreviated subject line and a single line of text for the body. Something to the effect of:

"Purchase Order No.: nnnnnnnnnnn

GB DE Terms Conditions April 2004.pdf GB DE Terms Conditions April 2004.pdf VSS Form Contractor Request Form.doc"

Because of the layout of the text, many of the users see it as spam when reviewing their emails. We therefore have a requirement to change this text.

As far as I can tell, this text is not taken from any Tasks nor from a Smartform. My feeling is that the program RSPPFPROCESS generates the text for the email before attaching the pdf of the PO to that email.

Does anyone know of a user exit/BAdI available to change the brief text generated on the email, or where in the program RSPPFPROCESS the subject line and text is generated?

Many thanks in advance for any help that can be given on this problem.
