BI Publisher bursting report Output stores in which table

 Hi gurus,I need to develop a functionality where in need to cut report output into multiple pieces based on the customer/invoice.

 

Like if i generate Pdf output of XML publisher report, then I need to cut again this report as per invoice number related to customer.

 

I know that bursting does this part and emails out. Based on the group it will trigger those emails to customer. Here i want to capture all those invoice wise pdf files into any clob custom table, which i will create. But I am not aware whether this files will be stored any else in the server of Oracle applications.
