Set merge rule for all objects
The Actions - Set rule for all menu item in the compare and merge window opens the Set merge rule for all objects dialog box.
Use this dialog box to specify the configuration
merge rule and object order options.
If the dialog box is opened during the update of a
supported configuration and external tool is specified for
comparing and merging (in Designer options, on the Compare/Merge
tab, in the Supported configuration update pane, in the Compare
with "Merge with external tool" rule field), the Merge
rule pane in this dialog box includes the Merge with
external tool option.
