Help me in pricing plss

Question

Hi frnds,
I am new to IPC of CRM.
I know there will be some pricing prod, cond types, records access sequence, but all these make confusion to me.
Could someone please give me an example and help me to understand the pricing.
For example, when i enter a product on sales order, how does the price comes?
If i want to give discount of 10% to a particular customer of a region how to do this? what code should i write in my IPC user exit?
Pls atleast give me one example from begininning to end till the price is calculated and displayed.
I read lot of docs but all have alot of stuff and it makes me not useful.
it will be great help if you explain in .
thanks in advance,
Niraja

Wanted to implmnt the below ABAP code in Java, im going very confusing here, can someone help me.
check preisfindungsart ne 'E'
   and   komp-kposn  ne '000000'
   and   xkomv-kinak ne 'A'
   and   xkomv-ksteu na 'EF'.
  CALL FUNCTION 'Z_GET_ROUNDING_FACTOR'
    EXPORTING
      vkorg    = komk-vkorg
      kdgrp    = komk-kdgrp
      bzirk    = komk-bzirk
      kschl    = xkomv-kschl
      kondm    = komp-kondm
      netpr    = komp-netpr
    IMPORTING
      rfactor  = w_zrfact
      quotient = w_zrquot.
No rounding required if the rounding factor is 1
  if w_zrquot = 0.
    check w_zrfact ne 1.
  endif.
  check w_zrfact ne 0.
  t_komv[] = tkomv[].
Determine tax total from prior conditions
  loop at t_komv where knumv = xkomv-knumv                  "
                 and   kposn < komp-kposn                   "
                 and ( kschl = 'ZTWS'             " Tax
                 or    kschl = 'ZRN4' ).          " Rounding
    if t_komv-kschl = 'ZTWS'.
      add t_komv-kwert to w_tax.
    endif.
    if t_komv-kschl = 'ZRN4'.
      add t_komv-kwert to w_rounding.
    endif.
  endloop.
Must add Tax value of current line which is in XKOMV
  t_komv[] = xkomv[].
  loop at t_komv where kschl = 'ZTWS'.            " Tax
    add t_komv-kwert to w_tax.
  endloop.
  w_tax_r  = w_tax.
  w_tax_r  = w_tax_r + w_zrquot.      " Add rounding quotient
  w_tax_r  = w_tax_r / w_zrfact.      " Rounding step 1
  w_tax_r  = w_tax_r * w_zrfact.      " Rounding step 2
  xkwert   = w_tax_r - w_tax - w_rounding.
