Unexpected partial reaults in Select statment.

Question

Hello all.
I've encountered a problem which i cannot explain:
When i write a query which look like this:
types: begin of ty_vbfa,
        vbelv type vbelv,
        posnv type posnr_von,
        vbeln type vbeln_nach,
        posnn type posnr_nach,
        rfwrt type rfwrt,
       end of ty_vbfa.
types: begin of ty_vbrp,
        vbeln type vbeln_vf,
        vgbel type vgbel,
        netwr type netwr_fp,
        ntgew type ntgew_15,
       end of ty_vbrp.
data: gt_vbfa          type table of ty_vbfa.
data: gt_vbrp          type table of vbrp.
and then:
select vbelv vbeln
      into corresponding fields of table lt_vbfa
      from vbfa
      where vbtyp_n in (lv_vbtyp_n_m, lv_vbtyp_n_n, lv_vbtyp_n_o, lv_vbtyp_n_s).
    sort lt_vbfa by vbeln.
    delete adjacent duplicates from lt_vbfa comparing vbeln.
    select *
    into corresponding fields of table gt_vbrp
    from vbrp
    for all entries in lt_vbfa
    where vbeln = lt_vbfa-vbeln.
I get 52000 results from vbrp.
but if i define the itabs like that:
data: gt_vbfa          type table of ty_vbfa.
data: gt_vbrp          type table of vbrp.
i get 67000 results which matches the number of results if i make the same query through se16.
What is the reason for that? is it something connected to the way those records are written in the DB (DB2)?
Kind regards.
Motty.

Hi Motty
I beleive you are fetching the records from VBRP for the entries present in table it_vbfa.
did you check whether the table lt_vbfa has values or not?
before using for all entires always chech the table whether it is empty or not And use all the primary keys fot vbrp
define the other primary keys as constants and use them in where condition with greater value to their initial value.
like: suppose you have fld1 fld2 fld3 as primary key in table it_vbfa,
define them in constants statement as:
Constants: c_fld1 type vbrp-fld1 value initial,
           c_fld2 type vbrp-fld1 value initial,
           c_fld3 type vbrp-fld1 value initial.
check not lt_vbfa is initial.
sort lt_vbfa.
select * into corresponding fields of table gt_vbrp
    from vbrp
    for all entries in lt_vbfa
    where vbeln = lt_vbfa-vbeln and
          fld1 gt c_fld1 and
          fld2 gt c_fld2 and
          fld3 gt c_fld3  .
It might be possible because you are selecting data in gt_vbrp for all entries present in it_vbfa thats why you are getting diffrent number of recordds.
I hope you will figure it out now.
thanks
