What is the need and relationship between WBS Summaries vs Activity Type WBS Summaries in Primavera P6?A project with ~1000 tasks and 10 summaries. Under the “Activities”-tab you will see both the WBS-summary without an ID-number and immediately below a schedule activity with an Activty ID defined as “WBS Summary”. Under General – Activity also has the same start / finish dates as all the schedule activities under each summary.
Question 1: How are the 2 WBS-summaries levels related? What is the purpose, benefits and/or risks?All is well, until you check the schedule log after a “Reschedule”. The log indicates there are 101 activities without a predecessor and 101 activities without a successor. When checking the project, there are no activities with out a predessessor or successor except the start date and the completion date. The activity ID’s are not present in the schedule log, now remove the filter applied above and observe that all the remaining 100+100 errors/warnings are coming from the WBS-summaries.
Question 2: Should activity type WBS summaries be linked to task dependent activities?
Question 3: Will linking the activity type WBS summaries to task dependent activities remove the error / warnings from the schedule log - without predecessors / successors?
