creating a type dynamically.

Hi Experts.

how can I create a type dynamically.

The number of its fileds depends on a user input (range field)

Regards

Hello Erdem,

Are you able to define the structures within your program, in a way then you can create some logic (which would include the range field)?

If I understood your point, then maybe you could try something this way:

TYPE-POOLS: SLIS.

DATA: G_REPID LIKE SY-REPID,

GS_PRINT TYPE SLIS_PRINT_ALV,

GT_LIST_TOP_OF_PAGE TYPE SLIS_T_LISTHEADER,

GT_EVENTS TYPE SLIS_T_EVENT,

GT_SORT TYPE SLIS_T_SORTINFO_ALV,

GS_LAYOUT TYPE SLIS_LAYOUT_ALV,

GT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,

FIELDCAT_LN LIKE LINE OF GT_FIELDCAT,

COL_POS TYPE I.

DATA: BEGIN OF ITAB,

FIELD1(5) TYPE C,

FIELD2(5) TYPE C,

FIELD3(5) TYPE P DECIMALS 2,

END OF ITAB.

DATA: BEGIN OF ITAB1 OCCURS 0.

INCLUDE STRUCTURE ITAB.

DATA: END OF ITAB1.

DATA: BEGIN OF ITAB_FIELDCAT OCCURS 0.

INCLUDE STRUCTURE ITAB.

DATA: END OF ITAB_FIELDCAT.

PARAMETERS:

P_PRINT AS CHECKBOX DEFAULT ' ', "PRINT IMMEDIATE

P_NOSINF AS CHECKBOX DEFAULT 'X', "NO SELECTION INFO

P_NOCOVE AS CHECKBOX DEFAULT ' ', "NO COVER PAGE

P_NONEWP AS CHECKBOX DEFAULT ' ', "NO NEW PAGE

P_NOLINF AS CHECKBOX DEFAULT 'X', "NO PRINT LIST INFO

P_RESERV TYPE I. "NO OF FOOTER LINE

INITIALIZATION.

G_REPID = SY-REPID.

PERFORM PRINT_BUILD USING GS_PRINT. "Print PARAMETERS

START-OF-SELECTION.

TEST

MOVE 'TEST1' TO ITAB1-FIELD1.

MOVE 'TEST1' TO ITAB1-FIELD2.

MOVE 'Value1' TO ITAB1-FIELD3.

APPEND ITAB1.

MOVE 'TEST2' TO ITAB1-FIELD1.

MOVE 'TEST2' TO ITAB1-FIELD2.

MOVE 'Value2' TO ITAB1-FIELD3.

APPEND ITAB1.

Here you can do some processing so that you get the resulting table entries to be displayed
