Create a flag for 3 way match on the base of three columns but values are not in the same rows

3way-match.png

I have a scenario where we have A PO Doc created by one user.

If the same user creates a Mat doc and Invoice against the same PO which was created by the same user then I want to see a flag which should say Match for this "3 way Match" and if not then "No Match".

The record from the back end are not coming in the same row.

My datasource is SAP BW query.

Please see attached screen shot.

I appreciate the response.

Thanks
