If material stock balance SC qty - R3 shud create PR

Question

The scenario is shud be like this:
If stock-material stock balance > SC qty -> R3 shud create Reservation.
If stock-material stock balance < SC qty -> R3 shud create Purchase Requisition.
But, unfortunately, R3 did not create PR for the second condition, and still create Reservation instead.
How do I make my condition works?

Hi
<b>Go to Transaction SE18</b>
Select the radio button for BADI Definitions.  There you need to give the BADI definition name.
Type the respective name -
You can either implement anyone of the BADIs to get this done.
<b>BBP_TARGET_OBJECTS
BBP_TARGET_OBJTYPE</b>
Then click on display button. a new window will open up.
On the top of that there will a menu item named - Implementation.
Click there and select the option to create and click there.
It will ask for creating a new implementation name.
Give any name starting with either Y or Z as the first charatcter, depends on your development system.
<b>Say i have given a name -
ZBBP_TARGET_OBJECTS  and then click ( enter  key ) ok button.</b>
Then <b>give the implementation na</b>me anything - badi for Preqs (Say).
then click on Interfaces tab,
<b>double-click on the method name displayed there. (in this case it should be DETERMINE_TARGET_OBJECTS )</b>
a new screen will be open up, then inside this
method ......
endmethod.
you can implement your code accordingly.
Like in my case, i have put the following sample code
<b>
method IF_EX_BBP_TARGET_OBJECTS~DETERMINE_TARGET_OBJECTS.
  data: w_item_data type BBP_BAPIPOGN.
  clear: w_item_data.
*--- loop through all items and for zero items set  to 2 for purchase requistion.
  loop at item_data into w_item_data.
     if w_item_data-C_AMT_BAPI = 0.
      w_item_data-OBJ_TO_GEN = '2'.
      modify item_data from w_item_data.
      clear: w_item_data.
     endif.
  endloop.
  clear: w_item_data.
endmethod.
</b>
<i>As you can see, if we change the value of the variable -
OBJ_TO_GEN =  2 (It creates a Purchase Requistion)
OBJ_TO_GEN =  3 (It creates a Purchase Order)
Here are the possible values
1     Reservation
2     Purchase Requisition
3     Purchase Order
4     Other usage for customer
5     Reserve
6     Reserve
7     Reserve
8     Reserve
9              Reserve</i>
Similarly, you can make your changes  in this code according to your requirement.
Hope this definitely help.
Pls reward suitable points.
