Hi All,

i am developing a class which will populate the fieldcatlog automatically . so pass the internal table to my class it_table. now i want to create the field catlog for the same..i have written a code as below.. but it dumps at the ASSIGN it_table-> TO <t_dyntable>.* it_table is of type any

Can any onehelp me out with this..

DATA: wa_fieldcat TYPE lvc_s_fcat,

it_fieldcat TYPE lvc_t_fcat,

it_tabdescr TYPE abap_compdescr_tab,

wa_tabdescr TYPE abap_compdescr,

ref_table_descr TYPE REF TO cl_abap_structdescr,

p_table TYPE char30 VALUE 'IT_TABLE'.

DATA: dref TYPE REF TO data.

DATA: newtable TYPE REF TO data.

DATA: newline TYPE REF TO data.

FIELD-SYMBOLS: <t_dyntable> TYPE STANDARD TABLE,

<fs_dyntable> TYPE any,

<fs_fldval> type any.

FIELD-SYMBOLS: <table> TYPE STANDARD TABLE,

<line> TYPE ANY.

ASSIGN it_table->* TO <t_dyntable>.

CREATE DATA newline LIKE LINE OF <t_dyntable>.

ref_table_descr ?= cl_abap_typedescr=>describe_by_name( p_table ).

it_tabdescr = ref_table_descr->components[].

LOOP AT it_tabdescr INTO wa_tabdescr.

CLEAR wa_fieldcat.

wa_fieldcat-fieldname = wa_tabdescr-name .

wa_fieldcat-datatype = wa_tabdescr-type_kind.

wa_fieldcat-inttype = wa_tabdescr-type_kind.

wa_fieldcat-intlen = wa_tabdescr-length.

wa_fieldcat-decimals = wa_tabdescr-decimals.

APPEND wa_fieldcat TO it_fieldcat.

ENDLOOP.

Hi Neha,

Modified program as below:

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

EXPORTING

IT_FIELDCATALOG = it_fieldcat

IMPORTING

EP_TABLE = IT_NEWTABLE.

ASSIGN IT_NEWTABLE->* TO <FS_T_DYNTABLE>

Create dynamic work area and assign to FS

CREATE DATA IT_NEWLINE LIKE LINE OF <FS_T_DYNTABLE>.

ASSIGN IT_NEWLINE->* TO <FS_DYNTABLE>.

Thanks

Hi Neha gupta,

You should use data object which is referenced to a field symbol in the ASSIGN statemnt on the lefthand side.

ASSIGN it_table->* TO <t_dyntable>.

Here it_table is not a data object. newtable is a data object you have already created in your pogram.Try with it instead of it_table.Another issue is it_table is not recognizable as variable in your program.it is a name of constant value which is assigned to p_table variable.

i hope , it will help you to sort out this problem.
