Is Bundle ID Suffix the same as the bundle identifier in info.plist?

What is Bundle ID Suffix? Tutorials said to use Bundle ID from info.plist; I can notice Bundle identifier in info.plist, its value is com.yourcompany.$(PRODUCT_NAME:rfc1034identifier)

Should I type (com.yourcompany.$(PRODUCT_NAME:rfc1034identifier) as Bundle ID Suffix?
