@mayshoonlettzaw81

your question is very unclear (at least for me) and possibly that is why no one has responded. Can you explain your use case and what are you going to do more clearly?

Hello, thanks for your suggestion. I want to carry the CustomNote field value from purchase order screen »  purchase receipt screen » tax and bills adjustment screen. Can anyone help me please.

Best Regards,

May

Again I am not sure what are these three fields but assuming they are custom fields which are added to those tables, you have a few options to develop them:

1.  Add a PXDBDefault attribute to the driven DAC fields or Row Persisting or Persisted event of the graph to read from base if users won’t be changing them on subsequent screens 

2. Add a PXDefault attribute to the driven DAC fields or a Field Defaulting handler to the graphs to set the values and allow users to modify if needed before save.
