Working with Multi-Select Array Field with setParentIncidentFields

[michaelsysec242]

Hello all,

I have an array of various IPs, and I want to set them to a case field using the setParentIncidentFields command. When defining the argument of values ${my.ips} only the last value is saved. I have tried join or split but to no success. Can anyone recommend what I can do to save multiple values here without overwriting the existing value. On the XSOAR we used to use Setincident and there is an option for multi-select append boolean. What transformer should I use so that every value is saved directly ?

Many thanks,

MR
