There are two ways to change data on your master schedule from the lookahead module. One is through progressing your lookahead activities. Outbuild will take the weighted average of that progress and reflect it in your master plan. The other way to change data is by submitting a modification request for more or less time at the lookahead level in Outbuild. Plan administrators will see these modification request tickets in the master plan and will have the option to preview, accept, or reject the request.
