Hi,

so at first i got a warning to use runOperation instead of Run

BP Rule: [BPUpgradeCodeRunBaseRunCalled]:
Methods should call the test.runOperation()method instead of the test.run() 
method on Runbase derived classes.Change the code from calling run to call runOperation.

when i switched to .RunOperation, i got the warning specified in the question (Method Runbase.canRunInNewSession must be overridden)

How to fix it?

Hi junior AX,

You can override canRunInNewSession method and return false. You can check the class AssetBudgetUpdate_Journal as an example.

protected boolean canRunInNewSession() { return false; }

Hi junior AX,

Please check this blog. Just override the canRunInNewSession method in your batch class.

Hi Gunjan and Will Wu

The class is not Mine. So if i override the method to false. Would that affect the class? ( the class didn't use this method so i guess it's set to true be default)
this method is used in form, so i wanted to call the logic from another class internally

and what does this method run in new session means?

Hi junior AX,

How is the method used on a form? Please check this thread for a detailed explanation regarding this method.

Hi Gunjan,

I mean there is a button on the form that calls a class as shown below

static void main(Args _args) { AAClass class; ; if (!_args || (_args && !_args.record())) { // logic } class = AAClass::construct(); class.getLast(); class.initFromArgs(_args); if (class.prompt()) { class.run(); class.refreshDataSource(); } }

so what i need to do is that i need to call the logic of this button in another class. so here's what i did:

public void AAMethod(AATable2 _table2) { AATable1 table1; while select table1 where table1.Id == _table2.Id { if( !table1.Id1) { Args args = new Args(); args.record(table1); AAClass class = AAClass::construct(); class.getLast(); class.initFromArgs(args); if (class.prompt()) { class.run(); } } } }

so my question is:

1. if I override canRunInNewSession to false, would that affect the actual button logic?

2. what does canRunInNewSession do?

3. what does if prompt() in the code mean?

1. No

2. I'm not 100% sure, but based on the name, and the comments above that method in RunBase class, it controls whether the class can run in a new session (=asynchronously, instead of your current user session) when you don't run it in batch. You can play around with it and try

3. prompt() method prints the dialog. If user clicks OK on the dialog, the method returns true. Otherwise it returns false and you should not run your logic.

Hi Nikolaos.

since i'm not using the button on the form and i copied the logic to call it by code. Then i don't need to add if class.prompt() right? i should call the run method directly right?

if (class.prompt()) { class.run(); }

but how come when i call it by code it enters class.run even though no dialog appears and i don't click ok?

Could be. Since we haven't seen any code from that actual class, we can't know.

Also, I suggest you to debug it to find more answers. Please share your learnings with us. Thanks!
