Hi,

In the onchange of the corresponding field you can write a function like this.

@api.onchange('field_name')
def set_caps(self):        
    val = str(self.field_name)
    self.field_name = val.upper()

string.upper() will capitalize the entered string

Thanks

Shouldn't you check if the value if not null (None) before transforming it?

Hello Kundan,

You can use onchange method to capitalize your field (Permanent Change)

In above image i have shown

customer is the field name that you want to capitalize, and you need not to check whether field is empty or not because empty field won't show any difference

Hope this will be helpful for you
