This is a very simple tip to create a dynamic internal table, ie. a table not defined until runtime, inside ABAP code.

OK, so it only references an SAP database table, but this should be good enough for most applications.

Code

There are a few declarations to make:

field-symbols: <table> type any.

types: fieldref type ref to data.

data: dyn_table type fieldref.

As for the actual code to generate the table:

create data dyn_table type (SAP Table).

assign dyn_table->* to table.

The table is now a field symbol which can be referenced in the normal way.

check this link it will be helpful

Try with the below code. This should work for you.

FIELD-SYMBOLS: <tab> TYPE STANDARD TABLE.

DATA: new_line TYPE REF TO data.

CREATE DATA new_line TYPE STANDARD TABLE OF (IO_TABLE).

ASSIGN new_line->* TO <tab>.

SELECT *

FROM (IO_TABLE)

INTO TABLE <tab>

WHERE ..

Hi Mahesh,

Compare with this code......


PARAMETER: tabname type dd02l-TABNAME.

DATA: stru_tab TYPE REF TO data.
FIELD-SYMBOLS <tab> TYPE table.

CREATE DATA stru_tab TYPE TABLE OF (tabname).
ASSIGN stru_tab->* TO <tab>.

Achyut
