I have retrieved a list of cases from a table, but the list contains duplicate data with the same IDs. How can I use the `pyRemoveDuplicatesFromPageList` function in my Activity to remove the duplicate entries?

My data is stored on the page `Primary.Response.Data`, and inside `Data`, there is an `ID` property

Hi @udaykumart16801936,

You can use OOTB function

@Utilities.pyRemoveDuplicatesFromPagelist(ListPage,PageListName,DuplicateCheckProperties) and pass the required mandatory parameters to remove duplicate items in the list.

In your scenario Configure like as this @Utilities.pyRemoveDuplicatesFromPagelist(Primary,“.Response.Data”,“ID”),

Please go through this
