Crystal reports 抑制节水晶报告中的行

所以我的两个子报告一个接一个地来了。在这种情况下，我得到了两行 一个接一个（一个来自子报表1页脚，另一个来自子报表2页眉）

---

现在，当有第二个子报告被搁置时，我需要抑制第一个子报告中的行。您有任何条件隐藏或显示子报告吗？您希望总是对SubRpt 1隐藏页脚还是有条件地隐藏页脚？

Hi All I have a report having two sub reports
In 1st sub report i have a line in report header and footer.
And in 2nd sub report i have a line in report header and footer.

I have not tried this solution but I think it will help.

    1] Create a global variable in your second sub report. 
    2] Set its counter to 0 and increment its value with the number of rows you are getting in  2nd sub report. 
    3] On 1st sub report go to format sub report and in suppress formula check whether global variable is greater than 0 if yes then it will suppress 1st sub report.

Not sure with the execution flow of crystal reports but its worth giving a try. let me know if you succeed.

Thanks,
Pratik
