MBO Development link

There are some of the best practices that can be implemented while developing Maximo codes or writing queries.

Some of points from this link are:

1.  Avoid using Yes\No\Cancel Exception. It is memory intensive since it repeats.  If you are forced to use, call Yes\No\Cancel logic in the code as early as possible.
2. "not in()" in the query will take much time to execute than "in()".
3. Setting of Field Flag (example: making Readonly) should not be done in the init() of mbo. It should be done in the initFieldFlagsonMbo();
