Recently I ran across a curious problem in Microsoft Dynamics CRM. Our client has 3 CRM organizations, one for development, one for testing and one for production. In Figure 1 you can see that on the Case form in TEST there was a button in the command bar called Create Child Case, but it was missing in the DEV organization as shown in Figure 2.
All three CRM organizations had been updated to Service Pack 1, but the new functionality was only available on the TEST and PROD organizations.
To get the button to appear on the DEV Case forms, I had to go to Settings >> Administration and click on Install Product Updates as shown in the bottom right corner of Figure 3.
On the next screen, click Next to apply the updates.
You will see a warning that the update cannot be uninstalled. If you are sure you want to go ahead, then click Yes and wait for the updates to install. Note that while the updates are installing the Dynamics CRM Organization will not be available to users.
Once I did this, and the updates were installed, I navigated back to the Case form and the Create Child Case button was available.
Note that this should also add a new area to your Settings area called Service Management.
