An end-user is not able to view an HTML report in the Offline platform when the Object Record Type (Account record type) field is defined.
The Object_RecordType_Id_vod__c is populated with the 15-digit Salesforce Id, instead of the 18-digit Record Type Id.
- Populate the Object_RecordType_Id_vod__c field with the SFDC 18-character Record Type Id based on the selected record type in the Object_RecordType_vod__c picklist.
- Ensure the user has Field Level Security (FLS) to the Object_RecordType_Id_vod__c and Object_RecordType_vod__c fields in the HTML_Report_vod__c object.
