Problem Description:
I have a
browser enabled InfoPath form loading in a Form web Part in a webpart page with
another connecting web part. When users try to open the form they get:
"An error occurred querying a data source"
Sympton-1: Occasional
error when opening an InfoPath form
Sympton-2: InfoPath
timeout random error first time form is loaded
Sympton-3: An error occurred querying a data source
Sympton-4: There was an
error retrieving data from a datasource.
Click OK if you want to resume filling in the form. Possibly
you might want to check the form for errors.
Sympton-5: There was an
error retrieving data from a datasource. An entry has been added to the Windows
event log of the server.
Log ID: 7893
Troubleshooting:
Best suggestion / recommended one is check the
SharePoint ULS logs and find out the exact root cause behind this error
message. I also did the same and found out that it is happening because of data
connection time outs.
Resolution:
The Maximum data connection timeout value you
modified is used to override all data connection time out values that specified
within form template code. If you are not specified the time out value within
form template code, please increase the default data connection timeout in
Central Administration.
-Central
Administration
-General
Application Settings
-Configure
InfoPath Forms Services
-Increase the
time out value and try again.
If you have any queries/questions based on the above
mentioned information then please let me know. I would be more than happy to
help you as well as resolves your issues, thank you.
