Comparing a Modified Process

This procedure describes how to use the Compare Process command.  The command enables you to compare two processes, one of which was originally copied from the other.  In addition, you can change the notes associated with the processes.

Compare Processes compares the contents of two PPR tree structures, where one of the selected tree structures was originally copied from the other.

For processes, this command reports:

• changed attribute values
• changed assigned items
• changed assigned resources
• new parent objects
• new child objects
• new sequence

For products, resources, and fasteners, this command reports:

• changed attribute values
• new parent objects
• new child objects

Compare Processes   also provides filtering capabilities to limit the objects or attributes to be checked. In addition, the Tools > Options > Digital Process for Manufacturing > Compare Tool tab allows you to set up to three pairs of attributes to be defined as compare conditions for processes, products, and resources.

• This command is only valid for PPR tree structures that were created via a copy. That is, one of the structures being compared was originally copied from the other.

• The two processes to be compared must both be open in the process windows before you start the command.

Compare Two Processes

1. Click Compare Processes in the PPR Tools toolbar.

2. Select the subtree in the PPR tree that is the original subtree (i.e., the one from which the second process was copied).

3. Select the subtree to be compared (i.e., the one you copied to create a modified process).

   The Compare Products - Filter dialog box appears.

   The Compare Process - Filter dialog box is used to determine what elements within the process are to be compared. The Attributes allows you to specify a single attribute by typing the name into the Single Attribute field, or specifying that All Attributes or No Attributes are compared. You can opt to have each, some, or all of following comparisons displayed (to have all comparisons displayed, click Activate All Comparisons): Check if assignment of items or manufacturing assemblies changed Check if assignment of resources changed Check if sequence changed Check if object was reparented Check if children were added or deleted In the Display Attributes section: Display all attributes is used to display a full list of all attributes, regardless of whether their values have changed. Display only values of changed attributes displays only those attributes with values that have changed. Display Summary Page creates an additional tab summarizing the changes.

4. Click OK.

   The Compare Process dialog box displays the output of the comparison.

   The Added Objects tab page lists any new objects that have been added to the copied subtree. The Removed Objects tab page lists any activities that have been deleted from the copied subtree. The Modified Objects tab page lists any activities that have been changed in the copied subtree. The Modified Objects tab page provides columns to indicate what has changed about each modified activity. Selecting a modified activity from the list discloses the changed attributes in the right frame of the dialog box, with the old and new values of the attribute. Double-click a modified activity in the list to highlight it and center it in the PPR tree view. In the Compare Process  dialog box, added and removed objects are always listed in the Added and Removed tabs, regardless of the options you chose in the Compare Process - Filter dialog box. Checking and unchecking options only has an effect on the Modified tab page.

   The result of the comparison is displayed beneath the Graphical Tree tab .

   The Summary tab provides a category by category summary of all comparisons.

   You can alter the order of the columns by clicking the Filter for displayed attributes button. The Attributes displayed in the summary page dialog box appears.  Use the right and left arrows to add or remove selected fields; use the up and and down arrows to alter the order. The possible attributes depend on the kind of process you have selected.  If, for instance, you have a process that contains wire harness data, wire gage and harness information are attributes that are available, in addition to those shown below.

Edit Comments of Assigned Change Orders

The Edit Comment to Change Order button in the Compare Process dialog box allows you to edit the Notes section of any assigned change order to be edited.

1. Click the Edit Comment to Change Order button.

   The Edit Change Order Notes dialog box appears.

   If more than one change order is assigned, the dialog box allows you to choose a specific change order.

   When you have finished editing the note, click OK; the Compare Process dialog box reappears. Any changes made to the notes of a change order are saved when the document used to perform the comparison is saved back to the database. If no change order is currently assigned to the compared object, you see the following error message.
