we need to write a custom function to call activity from data transform.

Use callActivity function from expression editor.

It is present in Pega-rules utilites function library.

callActivity available in Pega-Rules is a void return type function.

Thanks Ravi and Sahu! Yes, I checked that option from expression builder. But that can be used to call built-in function like update status. How can custom activities be called from DT?

You can call custom activities as well from data transform using callActivity() function.

Pass primaryPage and activityName to callActivity.

Syntax will be-

pega_rules_utilities.callActivity(PrimaryPageName, ActivityName, tools.getParameterPage()); 

would OOTB function pxExecuteAnActivity helps?

Solution: Use executeactivity function instead of CallActivity

hi,

can anyone give the example ?

i have tried , but failed :D.

what it should be used ? (screen shot)

use Param.Activity === @Utilities.pxExecuteAnActivity(PageName,ActiviyName) is DT
