Answer / madhusudhan
1. Date Validation you can do with TESTD
2. Duplicate Records. There are two ways to delete this
a. Through SQL, after selecting the RRN numbers, you can
use the delete statement in SQL to delete the unwanted
record based on the RRN
b. Through RPG, but if you use the SETLL and READE, all
the records along with the duplicates will get deleted , so
you need to use one variable for count, once it reaches 1 ,
stop doing the delete.

Hi Riyaz, Sorry I'm not Sumathi,
I guess maybe we can use SQL to do that.
