Error in WBS-Bar ???

This ‘error’ is usually the result of improperly relating the hammocks. Check to see that all hammock predecessors are Start-to-start and than all successors are Finish-to-finish. Improperly coded hammocks default to starting on the data date and finishing on project completion. Good luck!

Hi,

I prefer use WBS instead of hammock. you do not need to link it to other activities with logic, and you do not need to worr y about out-of-sequence when updating the schedule

Although they could not solve the problem, thank you for first answers. Each idea is very welcome.

= The linking of the hammocks is checked more than once by several people. Normal Early Finish does not give this problem only Actual Finish. We checked this problem with 2 persons, each having about 10 yrs of experience with P3. Of course this does not mean that we are perfect, but I think most common errors such as wrong linking are recognized.

= Yes, I prefer WBS as well. The whole project works with WBS-Code and WBS-Bars. But in this case a hammock (for piling activities) combines 4 normal activities beeing in different WBS-Groups all around the project. I.e. that no WBS-Bar can combine those activities, only a hammock.

There is an answer to this on the Primavera knowledgebase.

Thank you

"WBS-Activities were not designed to summarize "summary type"

This is called the "FIX" for the problem !!!!!!!

Hello Hannes,
I had a similar problem with WBS bar extending till the end of the project.

It took me quite some time to discover why till I found it:
The hammocks had also a WBS code - I removed the code from the Hammock and the problem was solved, with the WBS bar showing the correct duration of contained activities.

I hope it helps.

One other caution. Don’t use Hammock activities under the WBS structure. That is: remove WBS codes from hammock activities.

I’ve noticed when you organise by WBS that some Hammock activities don’t appear (depsite filtering all activities) and that these hidden hammocks can throw out the WBS activitiy type.

Solution is, to orgranise by Activity Codes (rather than WBS) and then Filter all Hammocks, and null their WBS codes. Then re-organise by WBS structure and the WBS bars should better reflect the dates.
