Function Module Problem

Former Member — Mon, 05 Dec 2011 14:47:07 GMT

Hello all,

I have a question to ask.

Have declared an internal table as follows:

types:tt_gps type table of ukv_gps with key ebeln.
data: gt_gps type tt_gps,
      gs_gps like line of gt_gps.

The Ebeln field is filled with values say 10 numbers.Now I want to use a select statement to put the corresponding Lieferant values into the itab gt_gps.

function zgps_read.
*"----------------------------------------------------------------------
*"*"Lokale Schnittstelle:
*"  TABLES
*"      GPS_TAB STRUCTURE  /BMW/UKV_GPS
*"  EXCEPTIONS
*"      SYSTEM_FAILURE
*"      COMMUNICATION_FAILURE
*"      NO_DATA
*"----------------------------------------------------------------------

  select /bmw/ukv_gps~llief into corresponding fields of table gps_tab  from /bmw/ukv_gps for all entries in
   gps_tab where ebeln = gps_tab-ebeln.
  if sy-subrc <> 0.
    message 'Nicht gefunden' type 'I' raising no_data.
    exit.
  endif.

endfunction.

Iam using in the FB,the same gps_tab as input and also filling the same gps_tab accordingly.

Thats not working properly.The gps_tab is getting filled with more than the needed values.

Regards

you couldl try something like:

function zgps_read.

*"----

""Lokale Schnittstelle:

*" TABLES

*" GPS_TAB STRUCTURE /BMW/UKV_GPS

*" EXCEPTIONS

*" SYSTEM_FAILURE

*" COMMUNICATION_FAILURE

*" NO_DATA

*"----

field-symbols <lfs_g> type /bmw/ukv_gps.

loop at gps_tab assigning <lfs_g>.

if <lfs_g> is assigned.

select llief into <lfs_g>-llief up to 1 rows "can select single instead?

from /bmw/ukv_gps

where vbeln eq <lfs_g>-vbeln.

endselect. "if can't do a select single (what is primary key?)

endif.

endloop.

at this point, gps_tab now contains the 2nd field for all VBELN entries that were found in the db table.

endfunction.

I don't think you can use the "FOR ALL ENTRIES IN" and "INTO CORRESPONDING FIELD OF TABLE" clauses on the same internal table gps_tab.

Try using different internal table for the INTO clause of the same type as gps_tab

Hi,

try to build a range-table and than modify during loop with field-symbols:



FIELD-SYMBOLS:
  <line>         TYPE /bmw/ukv_gps,
  <gps_line>  TYPE /bmw/ukv_gps.
DATA:
  lt_table  TYPE tt_gps,
  lrt_range TYPE RANGE OF ebeln.
  lr_range  LIKE LINE OF lrt_range.

lr_range-sign = 'I'.
lr_range-option = 'EQ'.
LOOP AT gps_tab ASSIGNING <gps_line>
  lr_range-low = <gps_line>-ebeln.
  append lr_range TO lrt_range.
ENDLOOP.

SELECT llief ebeln INTO CORRESPONDING FIELDS OF lt_table
  FROM /bmw/ukv_gps
 WHERE ebeln IN lrt_range.
IF sy-subrc <> 0.
  LOOP AT lt_table ASSIGNING <line>.
     READ TABLE gps_tab ASSIGNING <gps_line>
       WITH KEY ebeln = <line>-ebeln.
     if SY-subrc = 0.
* Modify directly the value in tab gps_tab
       <gps_line>-llief = <line>-llief.
     ENDIF:
  ENDLOOP.
ENDIF.

Kind regards,

Hendrik
