Checking a DMM

The data movement model is a very flexible tool, which allows you quickly to develop your model without constraints. You can check the validity of your DMM at any time.

A valid DMM conforms to the following kinds of rules:

Each object name in a DMM must be unique within its namespace
Each replication process must be linked to at least one process using a process connection or to at least one database or XML document using a data connection

Note: We recommend that you check your data movement model before generating scripts or another model from it . If the check encounters errors, generation will be stopped. The Check model option is enabled by default in the Generation dialog box.

You can check your model in any of the following ways:

Press F4, or
Select Tools > Check Model, or
Right-click the diagram background and select Check Model from the contextual menu

The Check Model Parameters dialog opens, allowing you to specify the kinds of checks to perform, and the objects to apply them to. The following sections document the DMM -specific checks available by default. For information about checks made on generic objects available in all model types and for detailed information about using the Check Model Parameters dialog, see Core Features Guide > The PowerDesigner Interface > Objects > Checking Models.
