Overview of Allow Model Bypass

You can specify whether users are required to select a model associated with a category when they create a change. As part of creating a change, users can choose whether to select a model, if you select or clear Allow Model Bypass for a selected category in the Change Category Manager dialog box. If Allow Model Bypass is selected, users have the option to skip, or bypass, the model application requirement and enter data manually in the Change dialog box.

You specify whether users are required to select a model for the category using the Allow Model Bypass option on the Category Detail tab of the Change Category Manager dialog box. Allow Model Bypass provides system administrators more control over the models applied to changes. If you clear Allow Model Bypass for a category, and there are associated models, users are required to select a model as part of creating a change.

Model selection summary The following table summarizes the possible combinations of models where Allow Model Bypass is selected, whether a default model is selected, and number of models per change category.

Examples

Restricting users to defined models

You create a change category named New_User, and two associated models, New_Hire and New_Manager. Assume since the majority of new users apply the New_Hire model, this model is defined as the default model. Therefore, when the change category New_User is selected to create a change, the default model New_Hire is automatically applied to the change. However, because there is more than one model defined for the New_User category, a user can select New_Manager from the Choose Models dialog box.
No restriction to defined models The New_Hire and New_Manager models are associated with the New_User change category, users are not restricted to defined models, but the default model is automatically assigned to a new change. New_User has Allow Model Bypass selected. As a result, when a user selects the category, the two models are listed and a Bypass button is available on the Choose Models dialog box. If a user chooses Bypass, no model is applied and the user completes the new change manually.
