Delta download for pricing conditions

Dear All,

Can some one explain me how to set the delta download for particular Condition types from r/3 to crm?

Senario: In our project Delta download is activated and one condtion type(zxcc) is getting download by deltadownload in crm.

Now i want to add some more condition types in delta download like PR00,K004,ZBSO,ZCSS, now these are downloading

by initial download(manually).

how can i set this restriction in delta download? So how can i download only particular condtion types by delta download?

Kindly suggest.

Regards,

shoki.
