Those tables are transit type of tables and depending on your volume of data, there are lot of deletes and inserts all the time resuling index fragmentation(holes due to deletes) and space usage.
The rebuilding not only release the space but also reduces the index fragmentation. If you don't have table truncation option for such tables then it is much better to rebuid indexes on such tables at regular interval to release space and for better performance.
As regard quantification, you many release sufficient amount of space if your usage is higher. Here it was 7.3.4 database so no LMT involved.

Please explain why these indexes must be built.
What benefits do you see from it?
Are they quantifiable?

John What about gl_interface table indexes? I think indexes on all *interface( tables must be rebuild on a regular interval...I was building indexes on gl_interfaces and fnd_request* tables on monthly basis.

Hemant,
This applies on 11i only. I would rebuild all indexes supporting the WF_ITEM_ACTIVITY_STATUSES and WF_ATTRIBUTE_VALUES tables. I have been working on some AOL table(space) problems in the background and noticed that in 11i by default, we are not be purging _all_ the WF data that we should be purging. I believe the current Purge routine purges activity rows whose persistence has expired and are marked 'TEMPORARY' and ignores those that are COMPLETE (see below). My contention is that it should be deleting old rows that are COMPLETEd... (Fyi, this is 12+ million rows...) Notes 141853.1, 144806.1, 132254.1, 148705.1, 148678.1 may help.
You could check this using the following SQLs
select activity_status, count(*) from applsys.wf_item_activity_statuses group by activity_status;
select item_type,activity_status,count(*) from applsys.wf_item_activity_statuses where activity_status='COMPLETE' group by item_type,activity_status;
Once the 'correct' purge is complete, the 'holey' indexes will need to be rebuilt and the WF_ tables copied/truncated/recopied to shrink the HWM to reasonable levels.
Let me know what your install shows up. John Kanagaraj DB Soft Inc Phone: 408-970-7002 (W)

John,
I rebuild the FND_CONCURRENT_REQUESTS indexes every four months [and the table itself, occassionally]. This Saturday I will also be rebuilding some ALR indexes. Which WorkFlow Indexes do you rebuild ?
