SAP B1 Journal Voucher Creator and Poster Query

Hi Experts

I am new to SAP B1 query generator. Basically I am trying to fetch both Creator and Poster of Journal Voucher. I am able to fetch Creator Name via OBTD table but I am unable to identify which field in OJDT table contains Poster name (even though it is visible under "Creator" when I open General ledger report)

Request you to please assist in resolving this issue. Thanks.

Regards
