Hi,

It is possible..

Refer to the code below ..

i have tested it..

DATA: BEGIN OF IT_TEXT OCCURS 100.

INCLUDE STRUCTURE TLINE.

DATA: END OF IT_TEXT.

DATA: BEGIN OF PO_TEXT OCCURS 1,

AUFNR like CAUFV-AUFNR,

AUART like CAUFV-AUART,

GSTRP like CAUFV-GSTRP,

IT_TEXT1 like IT_TEXT occurs 0,

END OF PO_TEXT.

Also refer to this thread..

Hi Maran,

Yes its possible and in SAP is its called as DEEP table.

Its defined as you normally define a internal table using a structure. In this case you need to use a already defined internal table for defining the DEEP internal table.

Cheers

USE THIS WAY

DATA: BEGIN OF ITAB1 OCCURS 0.

FIELD1,

FIELD2,

END OF ITAB1.

DATA: BEGIN OF ITAB2 OCCURS 0.

FIELD3,

FIELD4,

END OF ITAB2.

DATA: BEGIN OF ITAB OCCURS 0.

FIELD1,

FIELD2,

FIELD3,

FIELD4,

END OF ITAB.

NOW BY USING SELECT AND READ QUERY U CAN POPULATED ALL THE DATA OF ITAB1 AND ITAB2 INTO SINGLE INTERNAL TABLE ITAB.

Hi,

These are called nested internal tables.

You can create the same in different ways.

TYPES : BEING OF TYPE_TABLE,

FIELD1 TYPE C,

STYLE TYPE LVC_T_STYL,

END OF TYPE_TABLE.

DATA : T_dATA TYPE TABLE OF TYPE_TABLE.

As STYLE points to a TABLE by itself, it becomes a nested internal table. Now, for every row of Field1, STYLE can have multiple rows.

Hi Maran

Internal table inside internal table means Nested Internal Tables

ya its possible

jus have a look overr

First Internal Table type

types: begin of itab1 occurs 10,

f1 type i,

f2 type n,

end of itab.

Second internal table type having first internal table as its component:

types: begin of itab2 occurs 20,

f3 type n,

itab type itab1,

end of itab2.

now you can deifin your internal table as

data itab_final type table of itab2.

Thanks

Hi Maran,

It is possible and it is known as DEEP Table.

Check this link

<a href="http://help.sap.com/saphelp_erp2005/helpdata/en/fc/eb366d358411d1829f0000e829fbfe/frameset.htm">Deep table</a>

Here is an example:

TYPES VECTOR TYPE HASHED TABLE OF I WITH UNIQUE KEY TABLE LINE.

TYPES: BEGIN OF LINE,

COLUMN1 TYPE I,

COLUMN2 TYPE I,

COLUMN3 TYPE I,

END OF LINE.

TYPES ITAB TYPE SORTED TABLE OF LINE WITH UNIQUE KEY COLUMN1.

TYPES: BEGIN OF DEEPLINE,

FIELD TYPE C,

TABLE1 TYPE VECTOR,

TABLE2 TYPE ITAB,

END OF DEEPLINE.

TYPES DEEPTABLE TYPE STANDARD TABLE OF DEEPLINE

WITH DEFAULT KEY.

The program defines a table type VECTOR with type hashed table, the elementary line type I and a unique key of the entire table line. The second table type is the same as in the previous example. The structure DEEPLINE contains the internal table as a component. The table type DEEPTABLE has the line type DEEPLINE. Therefore, the elements of this internal table are themselves internal tables. The key is the default key - in this case the column FIELD. The key is non-unique, since the table is a standard table.

Hope it helps...
