While creating report the object is not visible. Checked the Allow Reports at object level. Any guess?

Hi Nitish,

If you have allowed report at object level,then a kind of possible problem is after creating the report type, some fields are missing in the report builder. This is because of custom fields have not been added to the report type.
To resolve this, Go to Setup > Create > Report Types.

Click on your Custom Report Type. At the bottom under Fields Available for Reports click Edit Layout. Then drag and drop the fields you want to display on report from right hand side panel and save it.

Thanks
