Pass the value to the main report using a shared / global variable. Put the sub-report in the section above, but don't fully suppress it. Have the value calculated in the sub-report within a ""hidden"" section (with everything else suppressed in the sub report). Sub-report formatting: suppress blank sub report. Main report section formatting: suppress blank section. This way the sub-report is executed (so the shared variable is calculated properly), but produces no output. Because you are bringing out the shared value in a normal main report formula field, it should export to Excel nicely.
