API to update Target_Start_Date and Target_Finish_Date for Project in 12.2.8

Hello Experts,

We recently upgraded to 12.2.8 from 12.1.3

I am using PA_PROJECT_PUB.UPDATE_PROJECT to update project dates.

In 12.1.3, while using API, when I pass start_date and completion_date, it was updating start_date and completion_date as well as target_start_date and target_finish_date.

In 12.2.8, same API call, only updates start_date and completion_date but is not changing target_start_date and target_finish_date.

Do I need different API to change target dates ?

Thanks in advance,
