SAP Cloud SDK : Event Trigger When Going to Field1 to Field2

Hi Experts,

Scenario : We have requirement on standard Account screen (QC) Quick Create when we enter the data into the fields under New Account screen (QC).

When we entered the Postal Code i need to check which event triggered and i need to fill some other fields.

1) Which event trigger when we move field 1 to field 2?

2) If no than any alternative way to achieve this ?

Regards,

Mithun
