How to get all the required fields of sObject dynamically?

Hi Prachi,

Well, Dynamic Apex API does not provide any direct property that will access required field but if any field is required they must have these three properties:-

a. It is creatable

b. It is not nillable.

3. It doesn't have a default value.

Example:-

Map<String, Schema.SObjectType> m = Schema.getGlobalDescribe();
Schema.SObjectType s = m.get('objectname');
Schema.DescribeSObjectResult r = s.getDescribe();
Map<String,Schema.SObjectField> fields = r.fields.getMap();

for(String field : fields.keyset()) {
Schema.DescribeFieldResult describeResult = fields.get(field).getDescribe();
if (describeResult.isCreateable() && !describeResult.isNillable() && !describeResult.isDefaultedOnCreate()) {
System.debug(field);
}
}

Hope this will help.

Thanks.
