Hi All,

I wanted to know if we can override Private method of child class into parent class ? If yes how?

If no then is there any way to do below issue?

In FormletterParmData ->Reaarange () I have written some custom code which works fine in all condition but when I calls Batch job it is creating issue.

So I wanted to write same code in SalesFormLetterParmDataInvoice. but it is throwing error as this rearrange method is private in FormletterParmData class. Please suggest how to handle this?

1) You cannot override private method it contradicts OOP

2) What kind of issue do you have in batch? Could you please share some details

Adding custom code in the core classes itself is not a good Idea. Go for 'Eventing' or 'Inheritance' as the first place.

RE: Can we override private method in X++

In batch job, I have used some Sysglobalcache variables which I am setting from my custom batch jobs and my custom form doing sales invoice.

When I am calling formletterParmData->rearrange() from Batch it is not getting Sysglobalcache vaule(which I am setting from my custom form) and so the error was coming if I comment this code it will work fine.

so I decided to override this method in subclass i.e SalesFormLetterParmDataInvoice.

You are doing very strange things. AX can have hundreds of concurrent users and hundreds of batch thread running simultaneously and playing with global cache is the last thing you want to do. You need to pass your parameter all the way through from your custom form to sales invoice posting if form instantiate this process.

However if you are doing some setup in one form and need to reuse it on posting and this two processes are independent you can create new table, write values from a from to it and analyse it on posting.

You can not override the private method as it mentioned as private in code, but if you think that standard private method should be public then you can create Extension Request to Microsoft...

There is an alternate way to call private method using reflection... it the provided blog works for you please mark this answer suggested.
