     itab-vbeln       length 10
select tdobject into table it_stxh
    from stxh
    for all entries in  itab
    where ( tdid = 'Z006' and tdspras = 'E'      and tdname+0(10) = itab-vbeln and tdobject = 'VBBK' ).
tdname+0(10) = itab-vbeln  ???

Answer 1

When you define the first Internal Table ITAB, define vbeln as the same type of stxh-tdname.
Eg.
  data: begin of itab occurs 0,
          vbeln like STXH-TDNAME,
          erdat like vbak-erdat,
          end of itab.
START-OF-SELECTION.
Select VBELN
          ERDAT
  from vbak
  into CORRSPONDING FIELDS of table itab.
Then you can directly use  this ITAB in the next query
  select tdobject into table it_stxh
  from stxh
  for all entries in itab
  where ( tdid = 'Z006' and tdspras = 'E' and tdname = itab-vbeln
  and tdobject = 'VBBK' ).
Pls reward it if it is useful.
