Regarding "BAPI_MATERIAL_AVAILABILITY" (important)

Question

Hi,
In my program, I use BAPI_MATERIAL_AVAILABILITY to get the <u><b>on-hand quantity in CSE.</b></u>
The following is my code:
    CALL FUNCTION 'BAPI_MATERIAL_AVAILABILITY'
      EXPORTING
        plant      = I_ZDAILY_MVMT-WERKS
        material   = I_ZDAILY_MVMT-MATNR
        unit       = 'CSE'
      IMPORTING
        av_qty_plt = bapi_onhand
        return     = return
      TABLES
        wmdvsx     = atp1
        wmdvex     = atp2.
    IF return IS INITIAL.
      READ TABLE atp2 WITH TABLE KEY bdcnt = 0
                                       req_date = sy-datum
                                       com_date = sy-datum.
     IF atp2-com_qty <> '9999999999.000'.
       I_ZDAILY_MVMT-ONHAND_VAL =  atp2-com_qty.
     ELSE.
        I_ZDAILY_MVMT-ONHAND_VAL =  bapi_onhand.
     ENDIF.
    ENDIF.
The problem is that if the commented section above is uncommented, i get extremely large and unreliable data (for example 163,333,333,333,333 - which doesn't make sense.)
On the other hand, when the commented sections are left commented, i get data that seems real.
Which is the right way and what am i doing wrong? How do i check if the data that i am getting is correct?
Thanks,
John

Hi,
What are the characteristics of  I_ZDAILY_MVMT-ONHAND_VAL?  Are you referencing bapi_on_hand with the section commented as being a correct value and I_ZDAILY_MVMT-ONHAND_VAL with the section not commented being an incorrect value?
