In Acumatica 23R1, the way you add activities and tasks to a custom screen has changed. You can see a demo of this functionality on the Customers (AR303000) Screen
In version 22R2 and earlier, all the functionality was wrapped into a single dataview:
public CRActivityList<YourMainGraphDAC> ActivityList;
In 23R1 however, this has now been replaced by two graph extensions
public class YourCustomGraph_ActivityDetailsExt_Actions : ActivityDetailsExt_Actions<
YourCustomGraph_ActivityDetailsExt, YourCustomGraph, YourMainDAC>
{
}
public class YourCustomGraph_ActivityDetailsExt : ActivityDetailsExt<YourCustomGraph, YourMainDAC, YourMainDAC.noteID>
{
}
After adding those two graph extensions, you can also reference the following include file in your ASPX.
<!--#include file="~\Pages\CR\Includes\ActivityDetailsExt\ActivityDetailsExt.inc"-->
That will automatically add all the necessary elements to the ASPX page to recreate what was shown on the ‘Customers’ screen
