The Engineer Change Order Dialog.

Summary

The Engineering Change Order dialog lists all modifications required to implement changes to one or more design documents, in order to satisfy the synchronization action requested. For example, you may be synchronizing the PCB document with its source schematics, or updating the parameters of placed components source schematics, with parameter information stored in source libraries or a company database. Whatever the specific action requested, the Engineering Change Order dialog allows you to browse, verify and ultimately execute the necessary modifications that comprise the ECO.

Access

To access this dialog, click Design » Update PCB Document in schematic editor or Design » Import Changes from in PCB editor.

Options/Controls

Modifications

Enable column - Shows which modifications will be included when the ECO is executed. Each entry in the list can be individually enabled/disabled. Alternatively, use the various right-click menu commands to enable/disable all entries in the list, all selected entries, or all entries of a particular modification type.
Action column - Each modification contains the specific action to be carried out, the object that will be affected by the action and the document upon which the modification will take place. The types of actions are dependent on what type of ECO needs to be done, such as Removing a net, Changing a footprint or Adding a room.
Affected Objects - List which objects are affected by the change.
Affected Document - List whhich documents are affected by the change.

Status

Check - Use the Validate Changes button to run a validation of all listed modifications in the ECO. The results of the validation will be shown in the Check column of the Status area of the dialog. A green tick means that the proposed change is supported and will be carried out upon execution of the ECO. A red cross means that the proposed change is invalid and will not be carried out when the ECO is executed.
Done - Clicking the Execute Changes button will effect all valid modifications. A green tick means that execution is successful.
Message - Shows the information of why validate or execute action fails.

Validate Changes - Click this button to validate the ECO before you can execute it. When an ECO is invalid (with a red cross in the Status column of the dialog), it means the required ECO is not possible for example, a component or a footprint could not be found because the required library is not loaded.

Execute Changes - Click this button to apply the ECO to synchronize the design documents. If the ECO is successful, the green tick appears on the Status Done column of the dialog.

Report Changes - Click this button to generate a report of Change Orders on affected documents of a design project.

Only Show Errors - Enable this option to only show Engineering Change Order errors and those that are validated changes will not show up. This option is good for reviewing a large number of entries and showing the list of errors only will enable you to quickly review and make necessary changes to your design.

If the Mode for a modification type has been set to Ignore Differences in the ECO Generation tab of the Options for Project dialog, then any design update that results in the action being of this modification type, will not be transferred to the Engineering Change Order dialog.
