Linking two fields in a dictionary view to the same field

Question

My DBA asked me if I knew how to do this without resorting to ABAP code, and I said I'd ask you guys over here.
A customer wants a view on several tables.  Vendor name from LFA1 is one of the
columns in the view.
He has two other columns in the view which can hold two different vendor numbers at the same time.
He wants the view to automatically bring in the names from LFA1 from both of them.
My DBA knows how to do this directly in DB2, of course, but can it be done in native SAP dictionary ???
Reason he's asking is because he suspects the customer wants to use the view directly in SQLQuery, where there's no chance for an ABAP code intercept.
Or is there?  Are there ABAP exits in dictionary views?  Or in SQLQueries?

Hi
We can straight away write a select statement to a database view similar to a TABLE in ABAP
see the sample views VIAUFKS and VIAUF_AFVC
and see the select statement below for this view
CLEAR: i_ord.
  REFRESH: i_ord.
  SELECT aufnr            " PM Order No
         equnr            " Equipment Number
         tplnr            " Functional Location
         auart            " Order Type
         aedat            " Order Date
         swerk            " Maintenance Plant
         werks            " Plant
         ktext            " Order Text
         kokrs            " Controlling Area
         objnr            " Object Id
         kostl            " Cost Center
    INTO TABLE i_ord
    FROM viaufks
    WHERE aufnr IN s_aufnr AND
          equnr IN s_equnr AND
          tplnr IN s_tplnr AND
          swerk IN s_swerk AND
          aedat IN s_date  AND
          auart IN s_auart.
