FI document no of MIGO

Dear Sirs,

Please help in finding FI document no that was generated by system while doing MIGO fo a particular purchase order.

i.e. let us suppose we had posted 100 MIGO for a particular purchase order, for which system provides two references,

1. material document no of MIGO

2. FI document no. of MIGO

we can access all 100 material document no through purchase order history in purchase document, but how to get all FI document of MIGO.
