SAP (AP and APP) payment approval process for check payment and other payments

Hi Gurus,

In my project that I am doing for a manufacturing plant, I understand that all the payments manual or automatic (check) would require an approval before release. Approval would be required from the supervisors, md, director. Different levels of approval will be required for a payment. I understand that we need to get a bit of help from workflow event tracking, but since I do not have any knowledge about the work flow management, could you please provide me the below inforamation:

1. What are the detailed configuration steps for starting and maintaining this approval process. Screenshots would be appreciated.

2. What are the things I should be careful on.

3. Please provide all the tcodes also. If somebody wants to send me the detailed process, my email address is tani2k6@gmail.com

Please treat this as an urgent request.

Regards

Urmila
