Assign statement does not work...

aris_hidalgo — Wed, 17 Sep 2008 06:45:18 GMT


Hello Experts, 

I am trying to pass the value of a field to a field-symbol but it does not work.
Please check my code below:

TYPES: BEGIN OF t_itab_name,
            itab_name TYPE char30,
           END OF t_itab_name.

DATA: lt_itab_name  TYPE STANDARD TABLE OF t_itab_name,
      wa_itab_name  LIKE LINE OF lt_itab_name.

FIELD-SYMBOLS: <fs_itab> TYPE table.

REFRESH lt_itab_name.
    DEFINE m_fill_itab_name.
      wa_itab_name-itab_name  = &1.
      append wa_itab_name to lt_itab_name.
      clear wa_itab_name.
    END-OF-DEFINITION.

    m_fill_itab_name 'ZSD_OUTPUT_ACQ'.
    m_fill_itab_name 'ZSD_OUTPUT_RET'.
    m_fill_itab_name 'ZSD_OUTPUT_NET'.

LOOP AT lt_itab_name INTO wa_itab_name.
      TRY.
          ASSIGN (wa_itab_name-itab_name) TO <fs_itab>.
        CATCH cx_sy_assign_cast_illegal_cast
              cx_sy_assign_cast_unknown_type
              cx_sy_assign_out_of_range.
      ENDTRY.
ENDLOOP.

Hope you can help me guys. Thank you and take care!

instead of statment

ASSIGN (wa_itab_name-itab_name) TO <fs_itab>.

Write

Assign wa_itab to <fs_itab>.

Also while defining the type of <fs_itab>

FIELD-SYMBOLS: <fs_itab> TYPE t_itab_name.

it should work now.

Hi,

Please use below code:

TYPES: BEGIN OF t_itab_name,

itab_name TYPE char30,

END OF t_itab_name.

DATA: lt_itab_name TYPE STANDARD TABLE OF t_itab_name,

wa_itab_name LIKE LINE OF lt_itab_name.

FIELD-SYMBOLS: <fs_itab> type char30.

REFRESH lt_itab_name.

DEFINE m_fill_itab_name.

wa_itab_name-itab_name = &1.

append wa_itab_name to lt_itab_name.

clear wa_itab_name.

END-OF-DEFINITION.

m_fill_itab_name 'ZSD_OUTPUT_ACQ'.

m_fill_itab_name 'ZSD_OUTPUT_RET'.

m_fill_itab_name 'ZSD_OUTPUT_NET'.

LOOP AT lt_itab_name INTO wa_itab_name.

TRY.

ASSIGN wa_itab_name-itab_name TO <fs_itab>.

CATCH cx_sy_assign_cast_illegal_cast

cx_sy_assign_cast_unknown_type

cx_sy_assign_out_of_range.

ENDTRY.

ENDLOOP.

Jana

Hi Bikas,

I cannot declare my field-symbols as the same type as my itab because I need to pass the value from the field-symbol to a FM parameter that has a TYPE TABLE.

Re: Assign statement does not work...

Former Member — Wed, 17 Sep 2008 06:55:06 GMT

Hi,

Plz code this way:

FIELD-SYMBOLS: <fs_itab> type char30.

thanx.

JozsefSzikszai — Wed, 17 Sep 2008 06:55:58 GMT

hi,

I think the problem is that the internal tables ('ZSD_OUTPUT_ACQ' and the other two), are not defined in the program, so you want to assign a field symbol to non existing objects.

hope this helps (some)

Hi Guys,

Like I said earlier, I cannot declare my field-symbols as type CHAR30 or like my itab because the value from the field-symbol will be passed to an FM parameter that has a TYPE OF TABLE.

So thats why I declared it as TABLE. Below is the complete code:

Hi,

to what do 'ZSD_OUTPUT_ACQ', 'ZSD_OUTPUT_RET', 'ZSD_OUTPUT_NET' refer??

the assign will only work if these are available at runtime..

Regards

Re: Assign statement does not work...

JozsefSzikszai — Wed, 17 Sep 2008 07:02:58 GMT

as I said above, ZSD_... is not declared as internal table, that is the problem. The line:

lt_output_acq TYPE STANDARD TABLE OF zsd_output_acq

indicates that it is type, which is not sufficient for the ASSIGN

Re: Assign statement does not work...

Former Member — Wed, 17 Sep 2008 07:04:14 GMT

Hi,

You have to declare type char30 and declare another varaible as Table and pass to that varaible , Second varaible pass to FM.

Hi Guys,

Those are custom tables that someone created that I need to use for fieldcatalog.

Re: Assign statement does not work...

JozsefSzikszai — Wed, 17 Sep 2008 07:07:37 GMT

just put a breakpoint on the ASSIGN statement and check how ZSD_OUTPUT_ACQ (and the other two) looks like during runtime. Looking at the code, it does not look like an internal table

Re: Assign statement does not work...

aris_hidalgo — Wed, 17 Sep 2008 07:10:51 GMT

Hi Eric,

Those are custom tables created in SE11 that I need to use as reference for the structure of my fieldcatalog so that is why I am passing it to the parameter 'i_structure_name' of FM 'REUSE_ALV_FIELDCATALOG_MERGE'.

Re: Assign statement does not work...

Former Member — Wed, 17 Sep 2008 07:13:11 GMT

Try using this way :

FIE

LD-SYMBOLS: <fs_itab> TYPE ANY table

thanx.

Re: Assign statement does not work...

JozsefSzikszai — Wed, 17 Sep 2008 07:14:25 GMT

OK, I see. But in this case you don't need the ASSIGN. You just pass the name of the table to the FM REUSE_ALV_FIELDCATALOGE_MERGE as you did. You can comment the line with ASSIGN (and everything else which belongs to it)
