Re: Remember value from previous row?

You have to use a tPerlFlex.
I tried to use your variables in the following example.
# start part of your Perl code
The variables initialisation
my $oldComponentColumnValue='';
my $componentColumnValue='first date';

# loop
-> tPerlFlex_1 is the tPerlFlex component unique name in my example
-> tPerlFlex_1 because beg_date is my second value in the schema (starting from 0)
$oldComponentColumnValue = $componentColumnValue;
$componentColumnValue = $tPerlFlex_1;

I'm waiting for your feedback.
