Extend Maximo Formula functionality to include DELETE updates

Maximo Formulas currently update parent objects on INSERT and UPDATE events.  However, they are not updated with DELETE events.

There is functionality created by my team in the Job Plans application that calculates the “Total Manhours for job” as the sum of the hours estimated on the planned labor lines. 

The calculation works fine when lines are added to the job plan labor. If a line is deleted, it does not recalculate, leaving the total higher than the sum of the lines. The following steps can be used to replicate this.

Open a draft job plan, or select to revise an active job plan
Note the total labor planned (if any exists) and the hours in the Total Manhours field.
Add a new planned labor row; after save, confirm the total hours calculated correctly.
Delete a row of labor. Note: the calculated value does not change and is higher than the sum of the lines. 
Add a new row of labor; the total amount should recalculated and be correct again after an extra row is added.

How it was implemented
- From Database configuration > JOBPLAN object > Attributes tab
- User defined field was created NEW_MANHOURS, Duration and 8 in Length
- Add/Modify formula for Attribute = sum$joblabor$new_tothrscalc
- then NEW_MANHOURS was added on the job plan screen

IBM should strongly consider fixing this deficiency in their Maximo Formula offering.  The APAR created was canceled because development decided parent object changes aren't supported, yet INSERT and UPDATE are supported so this explanation appears false.  IBM should do the right thing and fix this.
