Any functional module to get financial document based on billing document

Question

hi all,
do we have any functional module to get accounting document (bseg-BELNR) based on billing document (bseg-VBELN)?
i have a requirement to retrieve the clearing document (bseg-augcp) & date(bseg-augdt) from BSEG with billing document.
billing document is not a key, so i would like to retrieve the accounting document from any function module and use that to get clearing document (bseg-augcp) & date(bseg-augdt).
thanks.

        and AWTYP = 'VBRK'
        and AWKEY = billing doc.
      if sy-subrc EQ 0.
        select single * from bseg
        where bukrs = bkpf-bukrs
          and belnr = bkpf-belnr
          and gjahr = bkpf-gjahr.

          <data>-AUGDT = bseg-augdt.
          <data>-AUGBL = bseg-augbl.
