Table - MDTB (Urgent)

Hi All,

In MD04 (Stock / req list), i see a '' next to a purchase requisition, indicating it has been firmed by the system. I would like to know in which table i can get information for all materials having this '' for a given plant. I tried joining the tables MARD & MDTB, but the field FIX01, is not showing the data. Kindly let me know the field & the table i will get this information from. Hope my problem is clear, look forward for your inputs.
