We upgraded from v12.1.1 to v14.1
MSP 2013(without sp1) with 32bit Legacy Interface Clarity v14.1
The scheduler fails at receiving baseline details as shown in image below. This happened with more than 18 projects out of 25 project I tested.
I also looked at the difference in prj_baseline_Details table for same project in different environments.
In Dev I deleted and recreated the baseline and it worked. (has 375 rows)
In QA we still have the old baseline data as it is and it fails to Load (has 312 rows)
I am attaching the table here.
