Hi @danoj  Please find the template of the custom processing screen code. hope this helps!

 


  public class BulkSOProcess : PXGraph<BulkSOProcess>

        public PXCancel<MyFilterDAC> Cancel;

Thanks for the sample code.  By comparing the code sample with what we had, we could see that the delegate methodology update was missed.

Working great now...
