Unique ID Predecessors

[Robert Pickford]

Does this column work? It contains the same IDs as
Predecessors. Surely it should contain the Unique IDs of
the predecessor tasks.

Hi Robert,

The column definitely shows the UniqueID of the predecessors.
Note that unless you have moved or inserted tasks, ID and UniqueID are the
same.

Sorry, I missed out one important piece on information.
I'm dealing with a consolidated project. In that case the
Unique IDs are not the same as the IDs and Unique ID
Predecessors use the IDs not the Unique IDs.

eg
ID Name Unique ID Pred Unique
ID Pred
1 test 1 1
1 task 1 8388609
2 task 2 8388610 1 1
3 task 3 8388611 2 2
2 test 2 2
1 task 4 12582913
2 task 5 12582914 1 1
3 task 6 12582915 2 2

Is the a bug or a 'feature'.

Regards,
Robert

its a feature.

The UniqueID is unique only within each project. When you consolidate you
therefore may well get a specific UniqueID appearing in every sub-project.
In the consolidated project, UniqueIDs are made "really" unique by adding a
sub-project specific big number to each UniqueID.

The UniqueIDPredecessors field, on the other hand explicitly indicates which
project the predecessor is in, so doesn't need this big number added. For
example, a predecessor in the same sub-project will be something like "25"
while a predecessor in a different project will be "c:\pathname\test.mpp\25.

Hope this clarifies matters.
