How To Get All The Required Fields Of Sobject Dynamically?

HI

I think there is no direct property available in Apex dynamic API to represent the required field. However, there is another way to know about it.
If any field has below three properties then it is the mandatory field.
1.                  If it is Creatable
2.                  If it is not nullable and
3.                  If it does not have any default value

Thanks

Correct use can use metadat Api

Here is the ex:

public static Map<String, Schema.DescribeFieldResult> getFieldMetaData( Schema.DescribeSObjectResult dsor, Set<String> fields) { // the map to be returned with the final data Map<String,Schema.DescribeFieldResult> finalMap = new Map<String, Schema.DescribeFieldResult>(); // map of all fields in the object Map<String, Schema.SObjectField> objectFields = dsor.fields.getMap(); // iterate over the requested fields and get the describe info for each one. // add it to a map with field name as key for(String field : fields){ // skip fields that are not part of the object if (objectFields.containsKey(field)) { Schema.DescribeFieldResult dr = objectFields.get(field).getDescribe(); // add the results to the map to be returned finalMap.put(field, dr); } } return finalMap; }

Thanks
