Primavera P6 Enterprise Project Portfolio Management Cloud Service - Version and later
Information in this document applies to any platform.


After logging into Team Member, the following error occurs while loading the My Tasks page:

Clicking OK results in the page repeatedly attempting to load the Activity list.


The issue can be duplicated with the following steps:

  1. Login to P6 Professional.
  2. Create a project with a single Activity.
  3. Assign a Resource to the Activity.
  4. Enter a negative unit for the Activity's 'Remaining Units' (ex -10).  This will result in the Resource assignment inheriting a negative value. 
    (alternatively, assign a negative unit to the Resource assignment Remaining Units).
  5. Login to Team Member as the user tied to the assigned Resource.
  6. Note the error which occurs when loading the activity list.
