Hi,
We would like to setup a new field on bug issue type, only if 2 conditions are previously fulfilled on the bug:
Testing phase = FDR
Root cause = Data
In this case (when testing phase = FDR and Root cause = Data), the creating form should display a new field called "Data root cause" with the associated values: Data_BDR, Data_Master_Data, Data_Transactional_Data, Data_Reconciliation.
