how to create internal table dynamically?

hi all

I have a particular internal table in memory area( thru EXPORT TO MEMORY ID ....)

how can i create an internal table of this type in another program at runtime ?

this internal table need not be a data dictionary type.

i.e., i need to create an internal table of type which

is stored in a particular memory-id.

Regards,

Naveen........

Hi,

Check this code :

TYPE-POOLS: slis. 


 FIELD-SYMBOLS: <t_dyntable> TYPE STANDARD TABLE,  
                <fs_dyntable>,                     
                <fs_fldval> type any.              
PARAMETERS: p_cols(5) TYPE c.    

DATA:        t_newtable TYPE REF TO data, 
             t_newline  TYPE REF TO data, 
             t_fldcat   TYPE slis_t_fldcat_alv, 
             t_fldcat   TYPE lvc_t_fcat, 
             wa_it_fldcat TYPE lvc_s_fcat, 
             wa_colno(2) TYPE n, 
             wa_flname(5) TYPE c.  

* Create fields . 

  DO p_cols TIMES. 
    CLEAR wa_it_fldcat. 
    move sy-index to wa_colno. 
    concatenate 'COL' 
                wa_colno 
           into wa_flname. 
    wa_it_fldcat-fieldname = wa_flname. 
    wa_it_fldcat-datatype = 'CHAR'. 
    wa_it_fldcat-intlen = 10. 
    APPEND wa_it_fldcat TO t_fldcat. 
  ENDDO.  

* Create dynamic internal table and assign to FS 

  CALL METHOD cl_alv_table_create=>create_dynamic_table 
    EXPORTING 
      it_fieldcatalog = t_fldcat 
    IMPORTING 
      ep_table        = t_newtable.  

  ASSIGN t_newtable->* TO <t_dyntable>.  

* Create dynamic work area and assign to FS 

  CREATE DATA t_newline LIKE LINE OF <t_dyntable>. 

  ASSIGN t_newline->* TO <fs_dyntable>.

 

DATA it_fieldcatalog TYPE lvc_t_fcat. 
DATA lr_table TYPE REF TO data. 
FIELD-SYMBOLS <lt_table> TYPE table. 

*-- Import the fieldcatalog 
IMPORT it_fieldcatalog TO it_fieldcatalog 
       FROM MEMORY ID 'CREATE_DYNAMIC_TABLE'. 
IF sy-subrc <> 0. 
  EXIT. 
ENDIF. 

*-- Create the dynamic table with the field catalog as structure 
CALL METHOD cl_alv_table_create=>create_dynamic_table 
  EXPORTING 
    it_fieldcatalog           = it_fieldcatalog 
  IMPORTING 
    ep_table                  = lr_table 
  EXCEPTIONS 
    generate_subpool_dir_full = 1 
    OTHERS                    = 2. 
IF sy-subrc <> 0. 
  EXIT. 
ENDIF. 

*-- Convert the reference into a table 
ASSIGN lr_table->* TO <lt_table>. 
IF sy-subrc <> 0. 
  EXIT. 
ENDIF. 

*-- Export the created table so that the function module can import it 
EXPORT lt_table FROM <lt_table> 
       TO MEMORY ID 'CREATE_DYNAMIC_TABLE'.
