Hi James,
Thanks for your reply. The child ticket is being raised from a parent ticket BPM. When the ticket is created in the parent BPM the parent request ID is inserted in to the external reference of the child ticket. I would then within the Child ticket BPM reference the custom field of the parent ticket and copy it over.
The parent BPM has the following node:
In the child ticket BPM
Custom H - &[global["flowcoderefs"]["getReqInformation"]["externalRefNumber"]["customFieldG"]]
Kind Regards,
Salma
