Hiding Calculations in Subreports

크리스탈 리포트에서 미리 값을 계산 필요가 있다.

이때 subreport을 이용하여 데이터를 공유하여 가져오면 된다.

값데이터를 화면에 보여주지 않기 위해서는 다음과 같이 하면된다.

Fortunately, there is a way to hide the subreport but still have it run:

1. Create your subreport, and use the Section Expert in the subreport to hide or suppress all sections.
2. Return to the main report, select the section that holds the subreport and use the Section Expert to suppress the section if blank.
3. The subreport will be hidden in the report, but the calculations will still be performed.
