Help Needed Biztalk2006 BAM Infrastructure : ActiveRelationShip Table has two extra feilds

Hi,

     BAM automatically createSQL infrastructure automatically when we execute BAM.exe .

    in Biztalk2004 the BAM_xxx_ActiveRelationShip table had only 3 columns.ie

1. ActivityID
2. Reference Name
3. Reference Data

   But when we execute same BAM.exe in Biztalk 2006  BAM_xxx_ActiveRelationShip has two additional columns.ie

1. ReferenceType
2. LongReferenceData

  I am unable to understand the significance of these two new columns. Can any body help me out by putting light on to this issue.

 thanks in advance
