Can i go with single dso?

i have to get data from Extractor 0fi_gl_14  for Keyfigures A,B,C

and from Extractor   0FI_TX_4   for  keyfiguresE,F,H

I have common info objects as Account document no and G/L aCCOUNTS in both extractors .

can i simply connect both datasources to one DSO and Then to cube and creat Bex Report?

or i need to creat separte dso for each?
