Price Field Changeable while creating the Shopping cart

Question

Hi We are in SRM 4.0 and follow a classic scenarios.
For some materials we run program EBP_GET_BACKEND_PRICES
and get the prices from the backend, how ever while creating a shopping cart if the price differs we need to change the price but the field is grey.
how do we change the price ????
EX - My MAP in R/3 for Material A is  100 Rs. how ever while I create a shopping cart the price i need to enter is 102 how do I change the  price.
can anyone throw light on this.
regards,

Nimish,
for this you have to change the standard code.
In screen communication structures, there is a flag "price_changeable" that controls the edit mode of price field.
You have to change the standard logic to implement your behaviour in FORM price_changable_set from include LBBP_SC_APPF92:
  IF es_item-mode EQ gc_display OR
    ( es_item-rfq_ind EQ gc_yes AND es_item-price IS INITIAL ).
    CLEAR: es_item-price_changeable.
  ELSE.
    IF NOT es_item-catalogid IS INITIAL OR
       es_item-price_origin EQ c_price_origin_f OR
       iv_scenario EQ c_sc_generic_soco OR
       iv_scenario EQ c_sc_generic_history OR
       iv_scenario EQ c_sc_generic_workload OR
       ( es_item-price NE es_item-gross_price AND
         NOT es_item-price IS INITIAL ).
      CLEAR: es_item-price_changeable.
    ELSE.
      es_item-price_changeable = gc_yes.
    ENDIF.
  ENDIF.
