Problem in Mutiple Provider when identify characteristic.

Hi all,

The business scenario is: Three years' sales data are divided into four cube. There is a vip_number field in these cube. In order to join the vip informatin to the sales data, I created a Infoset for them.

Now I put a mutiple provider on the top of these infoset. But I can't continue when I doing idenify characteristic.

ZVIP_I01_F21 is the vip card create time.

ZVIP_I01_F4 is the sales time.
