How to create a BADI for the sceanrio

Question

Hi abapers,
I have a scenario as follows.
I create a Transaction where in i put the details of the product and quantity for a particular project's site. The amount gets calculated based on the products  unit value and its displayed in net value field. Now the user saves the transaction and a number gets generated. If the net value amount is less than 500 then the user can approve , if its greater than 501 and less than 1500 then a mail should be generated to his superior who is able to approve and ifs amount is greater than 1501 then a mail should be generated to the top of hierarchy who should approve it.
Now the real challenge is if the same project card  has more than 1  new request and the amount is less than 500 the user should not be able to approve  instead it should generate a mail to his hierarchy for approval  since  the site has already been exceeded its limit of approval. bcoz earlier 500 and current 400 which will make it to greater than 500.similarly for the hiearchy.How do i go about  it.
Now i want to create a BADI  on the save event of transaction to check the net value amount as well as check for earlier amounts saved for the particular site.
Any help will be appreciated.

r u using ECC 6.0 or 4.7 if 4.7 u can create badi defintiion directly form se18 transaction
and define the interface and its methods , once u define them activate them
and to use in ur code u create an instance of ur badi name
and then use
                 cl_exithandler=>get_instance  method in instance name parameter just pass ur badi name and this will create a badi defintion in ur code, and an oen can implement it
if u r usign ecc6.0 then u can either create new badis usign enhancments or classical badis
for clasical badis just go to menu  utilites and create classical badis and follw the sam eprocedure
