There is a parameter in spectrumgtw.cfg, Ticketing_System_Integrated_In, but is not clear what is the exact behavior it controls when its value is set to Spectrum.
Environment
UIM any version
Spectrum any version
Resolution
Ticketing_System_Integrated_In = Spectrum
With this change, this is the current behavior in regard to assignment:
Set assignee in UIM -> gets synced to Spectrum
Set assignee in Spectrum -> does not get synced to UIM and also does not get overwritten by UIM
Set new assignee in UIM -> gets synced to Spectrum and overwrites assignment set in Spectrum
