Create a blank project
Insert the two projects that should be related
View of projects I inserted.
Select the two tasks required to be dependent, and click the create link button
Now you can see I red bolded the text. Also note the predecessor/successors.
Select File –> Close. The first item saved will be your master project.
I simply named my Master Project so it’s ovbious
Subsequent saves will be for the sub-projects. I simply selected Yes to All to save the task links I created.
Now I opened up just the Training Plan B project. Although you see the inter-dependency, you do not see bold text.
I then opened the master project, and here you can see the links as well as the Red Bold font was saved.
