Error message when opening a Roadmap:
API-1006 : The value ''null'' for Attribute 'startDate' is not in expected format or is invalid.
Clarity PPM 15.7
Clarity PPM 15.6.1
Somehow the link between Roadmaps and Fiscal Time Periods is broken or NULL. It means the ID supossed to be referencing to a Fiscal Time Period is no longer valid in the Roadmap table. It normally happens if a Fiscal Time Period is removed or deativated. Even though it is added again, the issue remains.
Please, open a ticket at Broadcom Support because it requires a manual intervention. It is not recommended on production environments. Ask for assistance on this issue in order to avoid other unexpected issues as side-effect.
