Based on the document:
“PRC: How to Use 'Specify Skip Rule' Functionality in BPM to Ignore a Participant (Doc ID 2663059.1)”,
I performed the configuration, but it is not working as expected.

Specifically, when users “ORBPM-1” and “ORBPM-2” submit a requisition, I want to skip the rule assigned to a particular participant.
So, I configured the “Specify Skip Rule” with the following expression:
“ORBPM-1” and “ORBPM-2” are usernames set in user management.

contains('ORBPM-1,ORBPM-2', /task:task/task:payload/ns4:findReqHeaderDimensionResponse/ns4:result/ns2:EnteredByUsername)
