Assign entry.attr(counter1).attrval(counter2) to var issue

Question

Hi Friends,
we create a register procedure in OID PROVISIONING.
however. i got an error message as ORA-06502: PL/SQL: numeric or value error: NULL index table key value.
After debuging, we found that issue result assign null value .
when we assign as
user_vals(counter2) := entry.attr(counter1).attrval(counter2);
or l_xxx := entry.attr(counter1).attrval(counter2); again
It seems that that we can not assign entry.attr(counter1).attrval(counter2) to other var two time in procedure.
It is server configuration issue or code issue.
Thanks

Del,
You can distinguish dynamically generated Column headers by following option,
Distinguish categories of columns based on Restrictions (Actuals, Plan, Variance etc) and Concatenate those fields with Text Variables ("Jan 2008" + 'Actuals').
Try it out and let me know your inputs.
