I want to create customize report with different load cases which only shows max values of all load cases.

If i am selecting option of report type as summary it will show all load cases values and than give max value also.

Please guide if i only wnat to seee max(of different load cases for particular node) value how this is possible.

The max-only report is currently not available in the Static Output processor for Custom Reports; however, if your selection of load cases is somewhat predefined for a particular job (say, all OPE cases), you could do this in the Load Case Editor by creating an additional load case that would list the set of "predefined" load cases, and for the Combination Method select "Max" (or "Signed Max" if you prefer). Then run analysis, and in the Static Output processor simply select your "max" load case for report.
