Dear all,

I made some changes to this sample program from

My requirement now is the field-symbol should be generated from the internal table.

----

FORM CREATE_TABLE *

----

Create dynamic table *

----

FORM CREATE_TABLE USING MY_TAB TAB_NAME.

DATA L_STUFF TYPE TY_STUFF.

CREATE DATA DATAREF TYPE (MY_TAB).

ASSIGN DATAREF->* TO <FS>.

DESCR_STRUCT_REF ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <FS> ).

CLEAN_TABLE IT_FIELDCATALOG.

LOOP AT DESCR_STRUCT_REF->COMPONENTS ASSIGNING <COMPONENT>.

WA_FCAT-FIELDNAME = <COMPONENT>-NAME.

WA_FCAT-REF_TABLE = MY_TAB.

WA_FCAT-REF_FIELD = <COMPONENT>-NAME.

APPEND WA_FCAT TO IT_FIELDCATALOG.

ENDLOOP.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

EXPORTING

IT_FIELDCATALOG = IT_FIELDCATALOG

IMPORTING

EP_TABLE = DATAREF

EXCEPTIONS

OTHERS = 1.

ASSIGN DATAREF->* TO <DYN_TABLE>.

L_STUFF-TABNAME = TAB_NAME.

CREATE DATA L_STUFF-TDREF LIKE LINE OF <DYN_TABLE>.

ASSIGN L_STUFF-TDREF->* TO <DYN_WA>.

ENDFORM. "CREATE_TABLE

DESCR_STRUCT_REF ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <FS> ).

CLEAN_TABLE IT_FIELDCATALOG.
"<--Are you getting the components in this, is the loop success....check it once also change the fieldcatalog code..

LOOP AT DESCR_STRUCT_REF->COMPONENTS ASSIGNING <COMPONENT>.
 wa_fcat-fieldname = <component>-name .
    wa_fcat-datatype = <COMPONENT>-_kind.
    wa_fcat-inttype = <COMPONENT>--type_kind.
    wa_fcat-intlen = <COMPONENT>--length.
    wa_fcat-decimals = <COMPONENT>--decimals.

APPEND WA_FCAT TO IT_FIELDCATALOG.
ENDLOOP.
