Cross-project-area links using 'Satisfies' link type disappear under Baseline
One answer
When you create links between project areas, the link information is not stored equally - each link consists of two ends and the project area containing the outgoing link end stores most of the information, while the other project area containing the incoming link end only stores a 'back link'.
Baselines are project area specific, which means that only the outgoing link end is fully captured in baseline data. If you look at both sides of the link, you should find only the outgoing link end is visible in a baseline
Comments
Is there any solution to display both outgoing and incoming links in the baseline?
I also tried to use other link pairs for cross-project area linking, but only the one using 'Satisfies' can't be shown in the baseline, it's quite strange
No - you would need to take a baseline in both project areas, but they are independent unless you have set up a Global Configuration.
In order to use custom links across projects you need to have them defined identically in both project areas, and with the same URI.
