AP check sorting issue

Question

Hi All,
We need to sort check printing depending on the payroll area. The scenario below present the clear picture of our requirement.
Say for eg, we have three payroll area
P1
P2
P3
Now if i payroll area is  P1 then the check
should be printed based on sort criteria decided for payroll P1, as show below. similarly
the sort criteria for P2 and P3 are different from each other.
1. If payroll area is P1 then sorting should be done on location, last name, first name.
2. If payroll area is P2 then sorting should be done on last name, middle name, first name
3. If payroll area is P3 then sorting should be done on location , last name, middle name, first name.
should this be done by modifying the SAP std check printing program or is there  any other way like some user exit...

Hi pankaj,
1. I don't know whether there is user-exit
  for this program.
2. Even if there is one,
  it won't provide the functionality u won't.
3 Don't Modify the SAP Standard Code.
4. Instead copy the program to Y/Z
   and then understnd the code
   and accordingly write your own code (patch)
  for sorting puprose.
