Add and Enable the OMStdBundleActivationBackCompatibility Custom Setting

Before upgrading to Order Management 109.0.3 or later, you must add and enable a custom setting that allows for backward compatibility with older versions. You only need to do this once. The next time you upgrade, you won't have to do this step.

1. Click the Setup button at the top right of your org. If you're already in Setup, then you can skip this step.
   
2. In the Quick Find box, type Custom Settings, then click Custom Settings.
3. Find XOMSetup, and click the Manage link next to it. If you don't see XOMSetup, then click the X from among the letters at the top of the screen to filter out most of the options.
   
4. Click the New button at the top of the list.
   
5. Enter the following information in the fields:

   • In both the Name and Key fields, type or paste OMStdBundleActivationBackCompatibility

   • In the Value field, type or paste true

6. Click Save.
