Identify Header only documents

Hi,

I would like to know is there a way to identify header only(without line items) documents in FI.

i.e. technically what it means is entries will be there only in BKPF, where as there won't be corresponding line items entries in BSEG.

Scenario:

We are taking data by joining BKPF & BSEG to a target table. In case of header only documents, since the entries won't be available in BSEG, our join condition will fail and all such documents will be missed out while loading to target table.

Is there any way like a flag by which we can identify such documents?

Appreciate any help on this!

Thanks and Regards,
