Shopping Cart Approval - Changing the email text

Hi

I am new to SRM and Workflow so would really appreciate your help on this.

I have been asked to make a change to the text in the email thats sent to the approver of the shopping cart. Please see the link below which explains the requirement.

[Screenshot of requirement|http://img115.imageshack.us/img115/5476/srmscapproval.jpg].

The requirement is to replace the text at the bottom of the screenshot (red should be overwritten by green)

I have identified the the WF task as TS14508044 which deals with the approval, but I am not able to trace where the text is read from.

I would appreciate if you could please point to some document that explains this.

Thanks & Regards

Prav
