mbo is not recognized for Allow object creation script

 mbo is not recognized for Allow object creation script

If you are creating object creation script mbo is not recognized...

You need to use mboset instead of mbo 

so mbo.getOwner() should become mboset.getOwner()......

Maximo Migration Collection

This has been asked in various maximo interview questions and lot of developers don't know this because they don't use it much...

Well we develop components in Maximo or configure applications we maintain changes did for all task in Excel and give it to admin to extract. Admin extract them with the help of Object structures and migration groups..

we offcourse remove dependency at this time..

Now in migration collection we can define list of things we are modifying or changes we are doing or even we can enable an event on application so whenever a change is done like we create a new conditional expression in maximo this will be entered automatically in Collection application.

People don't use it much bcoz they don't know prior to development what all components they will modify..But as soon as developers get experience before doing the requirement or changes they know what all they will modify and start using maximo Migration collection application :)...

Maximo Table domain over Aln domain

Maximo Table  domain over Aln domain

sometimes we have requirement to filter aln domain, a way of it can be to create a table domain over the aln domain and apply list where clause.

Technically this design is not incorrent....

* Now their is a catch with this ... what suppose we want to further filter this with automation script...... when maximo build this list where clause 

domain type :- Table domain

ALN Domain :- Months

List where :-  domainid='MYMONTHDOMAIN' 

Automation script :- listwhere("month.startswith [J])

when we apply this to field that field might not respect your list where clause sometimes...so you might need reapply the domain in automation script on field..

so you in autoscript whereclause should be formed like

wherecaluse =domainid='monthdomain' and value in (value.statrtwith (J))

because maximo ignores what's coming with list where clause....
