Convert BI report into Crystal Report

Dear Sir,

I have drawn a structure in BI query onto Crystal Report,

my question is that, can I delete one single field from this structure on Crystal Report ?

'cause when I tried to delete one single field, the whole structure is deleted.

In addition, can I change the field name(text/description) on Crystal Report ?

Thank you very much for your help.

Best Regards,

Girai
