如何修改SAP Crystal Reports 2016 SP5中子报表的页面大小？

Hey there! I’ve run into this exact subreport page size problem before—those steps you tried make total sense, but subreports have a specific quirk: you need to edit their page settings as a standalone report, not from within the main report. Here’s how to do it right:

• First, open the subreport on its own. Don’t just click into it from the main report—navigate to where the subreport file is saved and open it directly (double-click it or use your reporting tool’s "Open" menu to select it).
• Once the subreport is open standalone, head to the Page Setup menu (this might be under the "File" tab, or a "Page Layout" section depending on your tool like Crystal Reports or SSRS).
• In the Page Setup window, first make sure you’ve selected a custom paper size if you’re using non-standard dimensions (sometimes it’s locked to Letter/A4 by default). Then adjust the "Horizontal" (width) and "Vertical" (height) values to what you need.
• Save the subreport, then go back to your main report. Right-click the subreport object and select "Refresh" or "Reload Subreport" to pull in the updated page size.

If you’re using Crystal Reports specifically, there’s one extra check:

• After setting the subreport’s page size, go back to the main report, right-click the subreport object and choose Format Subreport.
• In the Format Editor, go to the Subreport tab and make sure "Can Grow" is turned on. Also, match the subreport object’s width in the main report to the new page width of the subreport (or let it auto-adjust if that option’s available).

The reason your earlier steps didn’t work? When you right-click the subreport inside the main report and open Page Setup, you’re actually changing the main report’s settings—not the subreport’s. Resizing the subreport object in the main report just changes how much of it you can see, not the subreport’s own page dimensions.
