Here I am using two tables to print data from RTF file.
Table:1
Invoice	              Date	       Amount
ForEachINV           INVDATE          INVAMT
choose
when inv_num
INVNUM
end when
End foreachinv

Table:2
Invoice	             Date	      Amount
ForEachINV           INVDATE          INVAMT
choose
when inv_num
INVNUM
end when
End foreachinv

->For first table in when condition I am using 
<?when:INVNUM=10000-1,10000-2?> 
It needs to render the first table and fill all the details.

->For Second table in when condition I am using 
<?when:INVNUM=10000-3,10000-4?> 

If this condition is met it has to render the second table and fill the all information.
