LAG

I have a set of activities that I wish to put lag on. Out of two thousand activities, only 1000 need lag put on them. So global change would be out of the question.

Yeah

Thanks anyway for trying.

You have 1000 activities linked different ways. It is difficult to imagine a situation where each of those relationships will need a same amount of lag. If the lag is, for example, time between pouring concrete and striking formwork, and if you have forgotten to include this, and copied that series of activities for hundreds of sites, you have two choices: 1) work on one series and copy the the series again. 2) you won’t like it but if you are in the middle of the proejct and you are working on live programme, go on adding lag one by one.
