If you are creating a primary report based
on Table A and a subreport based on Table B:
The number of subreports that are run
is determined by the selection formula situation in the primary report:
If there is a selection formula
and it passes down range limits on Table A, the program runs a subreport only
for those records that satisfy range limit conditions (2).
If there is no selection formula,
or if the selection formula does not pass down range limits on Table A, the
program runs a subreport for every record in Table A (26).
The number of records read by each
subreport remains the same regardless of whether there was range limit
selection on Table A. Each subreport will read only those records in Table B
that match each record read in Table A (100).
