Hi Rob,
Try the following.
Step 1. Stop the webservice
Step 2. On the BODS Designer window right click on the Realtime job that is used for the webservice and select properties. This will open the properties dialog box as shown below.
In the properties window, un-check the "Use Collected Statistics" checkbox. Click on OK and Save the job.
Step 3: Restart the webservice
This should prevent the job from using collected statistics.
Do let me know the outcome.
kind regards
Raghu
