PO Output determination using Plant as a condition

Question

Hi All,
I want to use PLANT (werks) as a condition in PO output determination. How do I do that?
Basically, I want to be able to send ORDERS IDoc only when the Plant is a certain value. Where can I check the plant information before sending the output. I have tried to add plant in a condition table and then in the access sequence which is referenced in the output type. I have created a condition record for this condition table with PLANT also.
But for some reason when I save the PO it does not create a output message (ORDERS IDoc). If I use any other PO header field (like purch org or purch gp) in the condition it works and generates the ORDERS IDoc.
Any help would be greatly appreciated.
Thanks,
Sneha

Thanks Narayan.
It goes into the code for the requirement that I created to check for Plant and here is the code... But the structure KOMPBEA does not get populated with any values. Is there some other structure I can use to check the value for PLANT?
FORM KOBED_979.
*{   INSERT         TSTK941598                                        1
  IF KOMPBEA-WERKS = 'T300'.
    SY-SUBRC = 0.
  ELSE.
    SY-SUBRC = 4.
    EXIT.
  ENDIF.
*}   INSERT
ENDFORM.
FORM KOBEV_979.
*{   INSERT         TSTK941598                                        1
PERFORM KOBED_979.
*}   INSERT
ENDFORM.
