When a new phase is created in OWB, existing tasks are getting auto populated under the same.
Steps to reproduce:
Expected result: The task will be converted to a phase without any child tasks under the same.
Actual result: The task will be converted to phase and earlier tasks automatically comes under the same.
Due to defect DE35699.
CA PPM 15.2
There is a simple workaround to avoid this problem. This issue happens only only the existing phases are kept collapsed in the OWB. If the existing phases are expanded, user will not be facing the same problem while creating new phases from OWB.
The defect DE35699 is being reviewed by the development team and they will check if this can be fixed in any of the upcoming releases of CA PPM.
