To find the current user's default record type for Opportunity, the developer can use the DescribeSObjectResult and RecordTypeInfo classes.
Option A: Use Opportunity.SObjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate through them until isDefaultRecordTypeMapping() is true.
Correct Approach.
// Get describe result for Opportunity
Schema.DescribeSObjectResult oppDescribe = Opportunity.SObjectType.getDescribe();
// Get list of RecordTypeInfo
List<Schema.RecordTypeInfo> recordTypeInfos = oppDescribe.getRecordTypeInfos();
// Iterate through RecordTypeInfo to find the default one
Id defaultRecordTypeId;
for (Schema.RecordTypeInfo rtInfo : recordTypeInfos) {
if (rtInfo.isAvailable() && rtInfo.isDefaultRecordTypeMapping()) {
defaultRecordTypeId = rtInfo.getRecordTypeId();
break;
}
}
Reference:
Options Not Applicable:
Option B and C: Methods mentioned do not exist in the API.
Option D: Create the Opportunity and check the Opportunity.RecordTypeId before inserting.
The RecordTypeId is not automatically populated before inserting.
Conclusion:
To find the current user's default Opportunity record type, the developer should use Option A.
