The Status and % Complete of the Subproject Proxy tasks in the parent project are not always in sync with the Progress and % Complete on the actual subproject. Using the Manual option for % Complete Calculation Method allows the user to have combinations of % Complete and Progress on the Sub-project that would not otherwise be valid based on the relational rules of a regular task. This can cause the Proxy Task's Status to be out of sync with what is really on the Sub Project's Progress.
STEPS TO REPRODUCE:
This is caused by: DE59681
Release : 15.9, 15.9.1
Component : CA PPM SAAS PROJECT MANAGEMENT
Fixed in 15.9.2
Workaround: Update the % Complete of the subproject at the project level to trigger an update to the proxy task. The task status will update as well based on the % Complete (not necessarily off of the progress set at the project level).
