____________________________

 i want 600 as summation of both the columns FDAMT and ENCAMT.
is it possible to sum the FDAMT field on unique FDNo field basis ????

Insert a Subreport and Group on FDAMT.
Add a summary on FDAMT at grouplevel.
Sum({Data_.fdamt}, {Data_.fdamt})
Add a RunningTotal to count the no of records at each group.
#RTotalCount
Add a formula @distinctSum to calculate the distinct totals.
WhilePrintingRecords;
numbervar distinctSum;
distinctSum := distinctSum + Sum ({Data_.fdamt}, {Data_.fdamt}) / {#RTotalCount};
 
Now, using a shared variable you can pass this value to the main report!
Not sure, if this is the best solution.
