In pega we have several methods to propagate the data or update the data on the parent form child case. You can use the data transform by using the class pyWorkCover or you can take the page reference and set the data on the page or you can use the smart shape 'update case' to propagate the data.
But where to mention this data transform to update the pyworkcover. Can you please mention and also I need to propagate the same data to remaining sub cases I mean parallel cases. Thanks in advance.
