external sub-routine internal table

Former Member — Tue, 19 Aug 2008 18:34:02 GMT

Hello,

I am passing an internal table to an external sub-routine using the statement

PERFORM import_if
              IN PROGRAM zrpcetmx0 USING display_table-pernr
                                         seqnr_table-seqnr
                                         fldid
                                         CHANGING zl_table.

I declared the internal table like this in the main program

DATA zl_table TYPE zl_struc OCCURS 0 WITH HEADER LINE.

When I am trying to append the internal table zl_table in the sub-routine 'import_if' in the program ZRPCETMX0, it is giving a syntax error as ' "ZL_TABLE" is not an internal table'.

Please help me. As I see it, zl_table is an internal table right !

TABLES declared with the OCCURS 0 must be the in the first place in the parameters of the subroutine.

Like:


PERFORM import_if
              IN PROGRAM zrpcetmx0 
TABLES Z_Itable            "<<
USING display_table-pernr
           seqnr_table-seqnr
             fldid.

Subroutine must be:


FORM import_if.
TABLES Z_Itable            "<<
USING display_table-pernr
           seqnr_table-seqnr
             fldid.

ENDFORM.

when I am trying to pass the internal table with body zl_table[] as you said, the following syntax error is showing up.

"In unicode programs, the following characters cannot appear in names, as it does here in the name zl_table[]"

any other way to this perform ..

my friend suggests giving it as

      PERFORM import_if
              IN PROGRAM zrpcetmx9
              USING display_table-pernr
                    seqnr_table-seqnr
                    fldid CHANGING zl_table structure zl_struc.

I could not get that correct for the "structure zl_struc" part.

Thx in advance.

this is working for me..

REPORT  ZTEST_FORMTEST.


data: it_flight like TABLE OF sflight with HEADER LINE,
      wa_flight type sflight.

PERFORM test_form inprogram ZTEST_FORMTEST2 USING wa_flight
                 CHANGING it_flight[].

check it once from your end..

REPORT  ZTEST_FORMTEST2.


form test_form USING wa_flight type sflight
               CHANGING flight type sflight_tab1.



endform.

hello vijay,

I did change and see in the sub-routine (form)

FORM import_if
  USING $pernr
        $seqnr
        $fldid
        $wa_ztab TYPE zl_struc
  CHANGING zl_table TYPE zl_struc.

but the syntax error is ' The type "zl_struc" is unknown'.

Do I have to declare the structure in the sub-routine as well?

Also you in your example gave the sub-routine a different structure in the changing part, was that intentional?

form test_form USING wa_flight type sflight
               CHANGING flight type sflight_tab1.

the above one, we did not use sflight_tab1 structure anywhere right?

the code in the main program is like this

   PERFORM import_if
              IN PROGRAM zrpcetmx9 USING display_table-pernr
                                         seqnr_table-seqnr
                                         fldid
                                         wa_ztab
                                         changing zl_table[].

Thanks a lot for your help vijay .. once again

FORM import_if
  USING $pernr
        $seqnr
        $fldid
        $wa_ztab TYPE zl_struc
  CHANGING zl_table TYPE zl_t_struc.  "<------this should be table type

zl_t_struc should be table type, which can be exists in side the program or Global dictionary level se11 also.

you can also do this...this works inyour case

PERFORM import_if
              IN PROGRAM zrpcetmx9 USING display_table-pernr
                                         seqnr_table-seqnr
                                         fldid
                                         wa_ztab
                                         changing zl_table[].

FORM import_if
  USING $pernr
        $seqnr
        $fldid
        $wa_ztab TYPE zl_struc 
        CHANGING zl_table TYPE  type standard table.

Hi,

i think you are sending table structure which is not available globally then it should have some reference in called program

lets try this piece of code, u will understool

calling program

REPORT ZTEST_1.

data: begin of itab occurs 0,

line(10).

data end of itab.

itab-line = '1'.

append itab.

perform imp_sub in program ZTEST_2 TABLES itab.

REPORT ZTEST_2.

data: begin of itab1 occurs 0,

line(10).

data: end of itab1.

data w_line(10).

form imp_sub TABLES ITAB2 STRUCTURE ITAB1.

LOOP AT ITAB2 INTO W_LINE.

WRITE:/ W_LINE.

ENDLOOP.

endform.

this is how it works, no need to create any structure globally. Hope you got.

regards,
