Hi Experts,

      DATA: BEGIN OF line,
         col1 TYPE i,
         col2 TYPE i,
      END OF line.

DATA: itab1 TYPE TABLE OF line WITH HEADER LINE INITIAL SIZE 0.

Hi Poorna,

To get the runtime details of any variable there is a RTTI functins available.

for your querry checkout the cl_abap_structdescr class and its usage.

You need to create a structure variable as

Data itab1_struct like itab1.

and then call the abovt method with itab1_struct as an exporting parameter in the call statement.

In return you will get name,kind,length of the individual components of the structure you want to know at runtime.

Explore more in the RTTI (Real Time Type Identification) functionality in the help documentations for other details.

try out with following code.

you need to use DESCRIBE statement to have internal table details.

DATA: BEGIN OF LINE,

COL1 TYPE I,

COL2 TYPE I,

END OF LINE.

DATA ITAB LIKE HASHED TABLE OF LINE WITH UNIQUE KEY COL1

INITIAL SIZE 10.

DATA: LIN TYPE I,

INI TYPE I,

KND TYPE C.

<b>DESCRIBE TABLE ITAB LINES LIN OCCURS INI KIND KND.</b>

WRITE: / LIN, INI, KND.

DO 1000 TIMES.

LINE-COL1 = SY-INDEX.

LINE-COL2 = SY-INDEX ** 2.

INSERT LINE INTO TABLE ITAB.

ENDDO.

<b>DESCRIBE TABLE ITAB LINES LIN OCCURS INI KIND KND.</b>

WRITE: / LIN, INI, KND.

Hi,

To get internal table info you can see the "where used list" and to get the internal table column names you can use a function module called GET_COMPONENT_LIST .

CALL FUNCTION 'GET_COMPONENT_LIST'

EXPORTING

PROGRAM = sy-repid

FIELDNAME = 'WA_WBS'

TABLES

COMPONENTS = res1

.

'WA_WBS' - structure name to get column names

res1 - data res1 type table of rstrucinfo with header line.
