Unable to add function in filter criteria of extract rule

Hi,

I am using pega v8.1.2 and I am not able to add any function for the selected property in filter criteria in extract rule. Could anyone suggest me the possible solution for this?

@MagudeeswaranM9816 I guess in Pega 8.1.2 there is no support to add functions either in the value or in the field of BIX extract rule. I checked in 8.3 and I am able to add functions in both the places and able to save the rule successfully. Attaching the screen shot and reference article related to product for your reference. Unless function builder option appears functions cannot be added.
