Last night helped a netizen (VB-VC) to see the problem of crystal reports. She said that the sub-report data will not be displayed.
In her local computer can display, it is displayed on the server.
At the beginning, it was initially a server cache. Later, check the parameters first in the sub-report, OK.
I let her first remove the conditions. I still haven't shown on the server.
Determine the data source problem of the sub-report.
It turns out that she only fills the main report in the program. There is no filling of the sub-report. So there is no data at all.
But the program does not report an error, but it is only displayed. It should be prompted to have no presence.
Solution: You can set the data source as the test environment on the server can also be established on the server.
From 10:30 in the evening, it will be in the early morning.
