How to resolve a gap in task ID numbering

[Carlchat]

I have a Project 2003 schedule that's been published to Project Server. In
Project, the task IDs have a gap, like this:
1
2
3
8
9

Tasks 4 through 7 are not shown. The schedule has no filtering, sorting, or
grouping applied. I've tried resorting by ID but with no luck. The missing
tasks 4 through 7 are simply nowhere to be found in Project.

I mentioned that this schedule has been published to Project Server. There,
can see the mystery tasks 4 through 7 in the Project Center view.

Back in Project, I'd like to show the missing tasks 4 through 7, delete
them, and have Project correctly renumber the remaining tasks. Any
suggestions on how to accomplish this?

Thanks, Carlchat

Are there any external links? They can cause this behavior.

Bingo! That's exactly right. Tasks 4 through 7 did have external successor
links (I discovered this via the Tools/Links between projects command). I
deleted the external links there , the mystery tasks disappeared, and the
remaining task IDs renumbered correctly. Thanks!
