SubReports in Master Reports left Blank Space when reacheas at the end of the page and starts on new

[mihir_amreli]

Hello All I have encountered very strange problem while using Sub report in main report. I have a Sub Report with column title and a detail section both of height 20px. when the sub reports record displays on the main report it prints as expected until when it reaches at the bottom of the page. what happened at that time is , sub report prints just column header and left blank space , then again starts on new page with column header and its detail.so, what i want to do is either print the whole sub report on same page or start whole report from new page .

I am attaching here the detail section XML.

Thank You

You can use splitType = immediate . Try with that.

Thank You

for your reply. it perfectly worked but the type is Prevent not immediate.

 

Code:

<band height="20" splitType="Prevent">

Hi,

Am also facing the same prb and using splitType="Prevent" didnt help me as I dont want the subreport to be generated on the next page.

I have attached the screen shot.

Please help as this code has to go to production in a few days.

Thanks in advance.
