Transaction SCASE: setting workflow for credit limit requested

Dear All,

I need to configure a workflow for credit limit request approval on transaction SCASE, activating email notification (with attachments).

I read that I need to define process routes and link them to the approval matrix (I have a matrix with four approval levels according to amount).

How could I do this technically?

How could I define the approval matrix and link it to credit requested workflow and send it by email?

Thanks for support!
