Here you can add, edit, or remove EBMS Message Properties settings for the identified B2 B Profiles.
By Selecting "Synchronize Edits", any changes you make will be reflected, if possible, among all EBMS Message Properties settings for B2 B Profiles having the same name within the same domain, unless the changes are being made to newly added rows.
New rows are treated as their own group. This is to protect existing values from being arbitrarily changed to blank values found within new rows.
