For a task/checklist item to be displayed in an users dashboard the following criteria must be met

• The BP assigned to the Task/Checklist Item must be valid on the current date. If the BP validity period has expired the tasks will not be displayed.
• The status of the Task/Checklist Item should be 10 – Released or 11 – Released (Processing has begun)
• The parent node (can be project/phase/task/checklist header) must have one of the above statuses or 00 – Created.
• Plan start date and end date should be between 1st January 1900 and 31st December 9999 (highly unlikely you’ll fail this condition). Alternatively, both the dates should be initial, if any one is initial and the other is not, the entry will not be displayed on dashboard (E.g. Plan start date is 0, but end date is set to 31st Dec, 2050).

Tip: To debug how tasks/checklist items are selected, you can set a break point in method GET_TASKS / GET_CLI of class CL_PRP_RESOURCE_PROJECT.
