Hi, I have just created a new application in Manage based on a custom object. Its class is "psdi.mbo.custapp.CustomMboSet" and I have successfully created the relationships, domains, fields and non-persistent object for the CHANGESTATUS dialog etc. How can we implement the CHANGESTATUS function in this custom object without actually using a Java class? When I was trying to call the CHANGESTATUS function on the mbo from an automation script it gives an error "psdi.mbo.custapp.custommbo object has no attribute changestatus".

Any suggestions to implement a solution or workaround will be appreciated.

Thank you.

Hi Anurag,

I must admit that I'm not entirely sure whether this is doable without Java customization but I highly doubt that. I would love to hear from other community members what are your experiences?

Here is a couple reflections of mine.

Just by looking at other examples across Maximo to properly support status changes your MBO should extend psdi.mbo.StatefulMbo and implement abstract methods psdi.mbo.StatefulMbo#getStatusHandler, psdi.mbo.StatefulMbo#getStatusHistory and psdi.mbo.StatefulMbo#getStatusListName. Your object may need to have additional attributes as well.

Automation Scripting framework is powerful and allows you to define classes in runtime. Perhaps, except of being "hacky", this could be one way of providing your custom StatefulMbo implementation...

Hi Andrzej,

Thanks for the detailed reply, I appreciate you sharing your thoughts.

I agree that a fully native status implementation would typically require extending StatefulMbo and implementing those abstract methods. I wasn't able to implement those abstract methods directly, so I took a UI-driven approach instead by handling the requirement using an automation script without a launch point, triggered via a custom toolbar (change status) dialog. The script updates the project status directly on the parent MBO and records the audit details (changed by, date, memo) on OK.

In addition, I'm also running a separate automation script with an object launch point to auto-populate the non-persistent attributes from the persistent project object when the dialog opens. This keeps the UI consistent while avoiding direct Java customization. This whole function can only be triggered from the UI and will not work via integration or other methods.

I've attached screenshots of both scripts for reference.

Hi Anurag,

Fully agree with what Andrzej mentioned above. Everything that Change Status functionality does in Maximo is not possible to achieve from Automation Scripts, it depends of course on the customer requirements.

One thing which i believe can be difficult to achieve is the Change Status dialog being executed from the List tab, for multiple records, all the error handling, saving transactions,etc that is done in Maximo core.

Hope this helps.
