Field symbol assignment problem

Former Member — Wed, 11 Oct 2006 08:03:08 GMT

FIELD-SYMBOLS:<fs1> TYPE ANY,

<fs3> TYPE ANY.

fieldcat_ln-fieldname = 'SOD_ID'.

fieldcat_ln-tabname = 'IT_DASHBOARD'.

fieldcat_ln-datatype = 'CHAR'.

APPEND fieldcat_ln TO fieldcat.

APPEND wa_fieldcatalog TO gt_fieldcatalog_tot.

CLEAR fieldcat_ln.

fieldcat_ln-fieldname = 'BUSAREA'.

fieldcat_ln-tabname = 'IT_JRM'.

fieldcat_ln-datatype = 'CHAR'.

APPEND fieldcat_ln TO fieldcat.

APPEND wa_fieldcatalog TO gt_fieldcatalog_tot.

CLEAR fieldcat_ln.

LOOP AT gt_jrm.

AT NEW busarea.

CLEAR lv_field.

CONCATENATE 'BUSAREA-' gt_jrm-busarea INTO lv_field .

fieldcat_ln-fieldname = lv_field.

fieldcat_ln-tabname = 'IT_DASHBOARD'.

fieldcat_ln-datatype = 'CHAR'.

fieldcat_ln-outputlen = 5.

APPEND fieldcat_ln TO fieldcat.

APPEND wa_fieldcatalog TO gt_fieldcatalog_tot.

CLEAR fieldcat_ln.

ENDAT.

ENDLOOP.

ASSIGN fieldcat TO <fs3>.

ASSIGN COMPONENT 'SOD_ID' OF STRUCTURE <fs3> TO <fs1>.

<fs1> = 'ZZZZZZ'.

Getting the dump at the the line high-lighted above.

Pls. tell me what's the problem here.

The FIELDCATALOG hasn't the field SOD_ID, so the statament ASSIGN COMPONENT 'SOD_ID' OF STRUCTURE <fs3> TO <fs1> fails, and you'll have a dump when u insert a value in <fs1> because it isn't assigned yet.

You should write:

ASSIGN IT_DASHBOARD TO <FS3>.

ASSIGN COMPONENT 'SOD_ID' OF STRUCTURE <fs3> TO <fs1>.

IF SY-SUBRC = 0.

<FS1> = 'ZZZZ'.

ENDIF.

the fieldcatalog is having SOD_ID as shown in the below code that I gave

fieldcat_ln-fieldname = 'SOD_ID'.

fieldcat_ln-tabname = 'IT_DASHBOARD'.

fieldcat_ln-datatype = 'CHAR'.

APPEND fieldcat_ln TO fieldcat.

CLEAR fieldcat_ln.

No! The table IT_DASHBOARD has field SOD_ID not FIELDCAT, fieldcat has only a record where the field FIELDNAME = 'SOD_ID':

or you write:

ASSIGN IT_DASHBOARD TO <FS3>.

ASSIGN COMPONENT 'SOD_ID' OF STRUCTURE <fs3> TO <fs1>.

IF SY-SUBRC = 0.

<FS1> = 'ZZZZ'.

ENDIF.

or you write:

fieldname = 'IT_DASHBOARD-SOD_ID'.

ASSIGN (FIELDNAME) TO <FS1>.

<FS1> = 'ZZZZ'.

1) u cant assign structure

assign fieldcat to <fs3> directly like that.

u can do like below.

data:dref type ref to data.

create DATA dref type fieldcat.

assign dref->* to <fs3>.

field-symbols: <fs1> type any.

assign component 'SOD_ID' of structure <fs3> to <fs1>.

<fs1> = 'zzzz'.

actually i need to create dynamic table

so even fieldcatalog is dynamic in nature.

when I gave

create DATA dref type fieldcat.

it's giving error

as fieldcatalog is declared as shown below....

DATA: fieldcat TYPE slis_t_fieldcat_alv,

fieldcat_ln LIKE LINE OF fieldcat, "Field catalog

when I was coding in ABAP Objects I moved the dynamic field catalog table as shown below....

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = gt_fieldcatalog_tot

IMPORTING

ep_table = ref

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

ASSIGN ref->* TO <tabx>.

CREATE DATA dref LIKE LINE OF <tabx> .

ASSIGN dref->* TO <fs3> .

But If objects are not used how to create

create DATA dref type fieldcat.

I can't understand you want to do:

create DATA dref type fieldcat.

U shouldn't need it, but only:

DATA: MY_TABLE TYPE REF TO DATA,

WA TYPE REF TO DATA.

FIELD-SYMBOLS: <TAB> TYPE TABLE.

FIELD-SYMBOLS:<fs1> TYPE ANY,

<fs3> TYPE ANY.

fieldcat_ln-fieldname = 'SOD_ID'.

fieldcat_ln-datatype = 'CHAR'.

APPEND fieldcat_ln TO fieldcat.

APPEND wa_fieldcatalog TO gt_fieldcatalog_tot.

CLEAR fieldcat_ln.

fieldcat_ln-fieldname = 'BUSAREA'.

fieldcat_ln-datatype = 'CHAR'.

APPEND fieldcat_ln TO fieldcat.

APPEND wa_fieldcatalog TO gt_fieldcatalog_tot.

CLEAR fieldcat_ln.

LOOP AT gt_jrm.

AT NEW busarea.

CLEAR lv_field.

CONCATENATE 'BUSAREA-' gt_jrm-busarea INTO lv_field .

fieldcat_ln-fieldname = lv_field.

fieldcat_ln-tabname = 'IT_DASHBOARD'.

fieldcat_ln-datatype = 'CHAR'.

fieldcat_ln-outputlen = 5.

APPEND fieldcat_ln TO fieldcat.

APPEND wa_fieldcatalog TO gt_fieldcatalog_tot.

CLEAR fieldcat_ln.

ENDAT.

ENDLOOP.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = fieldcat

IMPORTING

ep_table = MY_TABLE

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

ASSIGN MY_TABLE->* TO <tab>.

CREATE DATA WA LIKE LINE OF <TAB> .

ASSIGN WA->* TO <fs3> .

ASSIGN COMPONENT 'SOD_ID' OF STRUCTURE <FS3> TO <FS1>.

<fs1> = 'ZZZZZZ'.
