Circular relationship - cannot find task

[Peter M.]

Hello,

I keep getting folowing error in MS Project after logging in:

There is a circular relationship in task <TASK_ID> etc.

But, the problem is, I can't see a task with <TASK_ID> in any of views. When
I try to add a new task, it just jump to number of mentioned task_id +1 (e.g.
the problem is in task nr. 2091, the last task I can see is task nr. 2090 and
when I try to add new task it jumps to 2092)

Any suggestions ?

Regards,

Hello,

Delete all links from and to summary tasks. Taht will make your circular
relationship disappear.

I too had this problem.
This was compounded by another peculiar problem that I cannot see any task
in the Gantt Chart View. when I change view to Resource Usage - I can see the
tasks assigned to Resources - but the Gantt chart View is absolutely blank.
A look into MSP_TASKS table shows the task names though.
Can anyone help

Hi,

You are looking at a resource pool, not the project file.

I know where I am looking.
I have 250 odd project plans with me as system admin for the MS Project
Implementation in my organisation.
I have checked all possible views and this is a peculiar problem

Hi Vivek,

I'm not sure what you mean then
"When I'm looking at the resource usage view I can see the tasks"
Nope.
You see assignments, not tasks (that is the case in a pool which dsoes not
shopw tasks but which has the assignments)
Maybe a detail, but could be important for our discussions.
Anyhow,
Can't you see any task in any view or is it just in one view?
I mean how does the Tracking Gantt look like?

 

[Vivek ARORA]

I cant see tasks in any view
Tracking gantt is also blank.
I used a third party freeware Projette to view the project plan - it shows
correctly.
If you can give me your mail ID, I can send across the file (.mpp) to you to
have a look
I am at (e-mail address removed)

Thanks and Regards
Vivek

Hi,

My mail address can be decyphered by replacing AT by @ in:

(Never use a clear e-mail address in a public place to avoid spam)

I'm really curious.

When you cannot see a task it is an external task. Select Tools Options View
Show External Predecessors and Successors or copy the macros below to your
global and assign them to a button on your tool bar for frequent use.

I have found external tasks linked to other external tasks, which should
never happen.

Sub TurnOffExternal()
OptionsView DisplayExternalSuccessors:=False,
DisplayExternalPredecessors:=False
End Sub
Sub TurnOnExternal()
OptionsView DisplayExternalSuccessors:=True,
DisplayExternalPredecessors:=True
End Sub
