'Changes to' operator missing in Flow trigger conditions

[JanRasehorn]

Hi guys,

after upgrading my PDI to Australia I miss the "Changes to" operator in the Flow Designer trigger conditions. There is a warning shown for the flows I created under Zurich, that the operator is not recognized and not supported.

Is there any other way intended by ServiceNow to limit the flow execution to situations when a certain value is set rather than just given?

Hi @JanRasehorn 

Its a known issue. Refer KB : KB2913413 Workflow Studio/Flow designer missing condition operator "'changes', 'changes to', and 'ch... 

Cause

This issue has been identified as a defect, and PRB2005619 has been logged to address the problem.

Resolution

The PRB2005619 is currently in investiagtion phase and in the meanwhile the customer can use the below workaround:

1. Add the property 'sn_flow_designer.predicate_builder_enabled' in the effected instance and set it to false. This enables the display of 'changes', 'changes to', and 'changes from' in the trigger condition operators.
2. After applying this workaround, the missing trigger condition operators should be visible.
