@jinnypt,

Does this work for you ?

"your search terms for getting the fields "
| streamstats current=f window=1 last(at) as prev_at, last(bt) as prev_bt,last(ct) as prev_ct,count as rownum by name reset_on_change=true
| eval at=coalesce(at,prev_at),bt=coalesce(bt,prev_bt),ct=coalesce(ct,prev_ct)
| eval a=if(at=="ok","Y","N"),b=if(bt=="ok","Y","N"),c=if(ct=="ok","Y","N")
| where rownum=1
| table name,a,b,c,at,bt,ct

Or run anywhere example with if instead of coalesce in case you have "" instead of a null value

      count as rownum by name reset_on_change=true
