I have to validate a field that is vbeln. if vbeln, bukrs,lifnr and fkdat all these three are in table I sshould throw some error else I would allow..

(All the four fields are in y table)

CHAIN.
    FIELD: your_field
      MODULE validation.
  ENDCHAIN.

fkdat

from <table name>

into table <internal table>

where vbeln = vbeln.

if sy-subrc eq0.
