Can not delete table in SQVI

Hi,

As my purpose,I insert vendor master table,LFA1,ADRC,LFM1 and LFBK to get vendor master data.

I executed my quick view composed successfully.

Now I do not want bank details of vendors, so I wanna delete table LFBK.

SQVI gave the message "Tables of joins can no longer be deleted in QuickView".

Could you give me some advice?
