Hi Jennie,
First, you can consolidate all Invoice Receipts / Credit Memo from MIRO (MM).
Then in SE16N using BKPF (FI Accounting Document Header), search for Reference Key (BKPF-AWKEY).
BKPF-AWKEY = Invoice Number + Year
example: 51000000012015
Then execute.
You can now see all Accounting Documents that are associated with MIRO Documents you specified.
Thanks!
