What methods are called when a runbaseBatch process is executed?

It can be handy to have detailed knowledge on the runbaseBatch class. In this tutorial I will explain the calling sequence of the RunBaseBatch class with a query (select button).

We will start this process with a static construct function that will force the runbaseBatch process to run on the server. 

In the left column of below table is shown the method name of the runbase batch and the location where it is running. The order of the lines in the table is also the order AX will execute the methods.

(Note: The runbase mechanism calls sometimes methods twice, these duplicate call are removed from this list.)

Server construct	Our constructor will execute the new method
Server new
Server prompt
Server unpack
Server showdialog
Server pack
Client new	Reconstruct the class on the AX client
Client unpack	Get the values from the previous run
Client canGoBatch	Do we need to show the batch tab page
Client prompt
Client showdialog	Do we need to show dialog
Client caption	Set the caption of the dialog
Client queryRun	Get the query object (if exist)
Client showQueryValues	Do we need to query values on the general tab page of the dialog
Client showQuerySelectButton	Do we need to query select button on the dialog
Client showDefaultButton	Do we need default button
Client showClearButton	Do we need clear button
Client dialog	Build your dialog (don’t remove super otherwise you don’t see the batch tab page
Client dialogPostRun	Used to make additional modification to the dialog (field High), set overload methods

Finally our dialog appears on the screen.

Next we press the OK button. The next methods of the runbaseBatch will be executed:

Client getFromDialog	We get the values from the dialog , don’t remove super otherwise batch and select info is gone
Client validate	Check if all dialog values are valid
Client pack	Store the values in the SysLastValue table
Server unpack	Readout the values from the SysLastValue table
Server canGoBatch	Check if we have to run in batch
Server run	Run the process (can be from batch process)
