HI Andreas ,
I urgently need help on this query.
Did you manage to run the code and create the results please .
Hi @MV04
In your results, shouldn't
123 | 5.62 | 01-Jun-09 |
be 4.88?
as table1 effectivedate look up is
123 | 4.88 | 01-Jun-09 |
So if the above understanding and assumption of mine is correct, the following should work
data table1;
format Effective_date date9.;
infile cards dlm= "," dsd;
input id rate Effective_date ddmmyy10.;
cards ;
