Hi

Create the fieldcatalog thru the FM

 CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
       EXPORTING
            i_structure_name = in_tabname
       CHANGING
            ct_fieldcat      = it_fcat
       EXCEPTIONS
            OTHERS           = 1.

then append the number of dynamic fields you want to into the Fieldcatalog and then call on the following class

CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = it_fcat
    IMPORTING
      ep_table        = it_content.
  IF sy-subrc = 0.
    ASSIGN it_content->* TO <itab>.
  ELSE.
    WRITE: 'Error creating internal table'.
    STOP.
  ENDIF.

This will return you a table whose fields will increase decrease dynamically.

Hope that Helps

Hi Mrudula,

Check this code.

DATA: BEGIN OF str_itab OCCURS 0,

var1 TYPE i,

var2 TYPE i,

END OF str_itab.

CREATE DATA itab TYPE STANDARD TABLE OF itab.

By using 'create data' statement you can create internal table dynamically.

regards,

Rajesh.

Hi Mrudula,

In order to increase the size of the internal table , i.e. fields dynamically , you need to include or append structures to the respective internal table.

Hope this resolves your query.

Reward all the helpful answers.
