Lookup Object Report

Content

Hi Gurus,

We have maintained one stand-alone custom object which maintain the details of the promo-code. The promo-code value will receive from third party system and we load it under Contact's child object. 

Our objective is, we need to create one report for knowing the details of the promotion code in the Contact's child table report. But when I tried to create a report based on Contact's child object, I could not find the relationship with my custom object. Is it possible to create a report without any relationship with other object? 

Thanks,

Mohan
