Making screen fields non-editable in standard SAP screen
I have a reuirement. In transaction code CAA2 I have to make the field 'Incoming payment method' (EZAWE) as read only/non-editable. This field is available in table FKKVKP. We can make this field as read only by performing some configuration setting. But this field needs to be disabled based on some validations.
For example EZAWE field should appear in changable mode when user has the role 'ZDJ: SUPER_USER' assigned to him. If the user does not hold this role the EZAWE fields needs to be disabled.
One more thing here I don't have to use screen variants for this.
