In Strategy 9.x users may want to delete some of the objects found in the object browser pane on the Strategy freeform SQL editor. However, when right clicking on any of those objects there is no delete option as shown below:

Here are the steps to delete these objects:
1. On Strategy Developer, select on the top toolbar menu 'Tools', select the 'Search for Objects' menu.

2. Once the object search window opens, on the top menu bar select 'Tools' and then 'Options'. Check the following options: 'Display hidden objects', 'Display Managed objects', and 'Display managed objects only'.

3. Click on `OK` and `Find now`. The list of freeform sql objects (managed by the system) should now show up. Right click on any of them and select `delete` to remove them.
