How to collect records in crystal report using record selection formula to concatenate records -

-

what want collect records using record selection formula on basis of criteria selection.

if have 2 criteria's have 4 combinations using criteria selection. e.g.

if(cri1 <> 'all' , cri2 <> 'all') record fetched
else if(cri1 = 'all' , cri2 <> 'all') record fetched
else if(cri <> 'all' , cri = 'all') record fetched
else if(cri = 'all' ; cri = 'all') record fetched

(cri1 , cri2 parameter fields used in crystal report)

in same way 3 criteria's, have 8 combinations. is, n criteria's having '2' power of 'n' combinations means 10 criteria's having 2 power of 10 combinations (i.e. 1024) combinations.

well want know whether there way collect data in simpler way n number of criteria's. because more 3 criteria's confusing collect records.

** please on this..**
