Solved!

Clever colleagues sorted it out for me. Tau will be used as an id. For each
unique tau I now calculate t1 and t2 and merge with lambda(t1) and Fl(t2).
The sum (for each unique tau) of lambda(t1) * Fl(t2) is stored in a dataset
with tau. As I know tau for each item, the lambda-Fl sum is easily added to
each and every item.

I also skipped the macro and do the summary for each period k later in the
program.
