Creating an internal table dynamically

Former Member — Fri, 17 Feb 2006 16:32:24 GMT

Hi Guys,

I have a requirement where in I need to create an internal table after user inputting.

I have a parameter where the user enters the Table Name.I need to create dynamic internal table for the table entered by the user.How can I do it??

<b>Note: This is a requirement for 3.1I Version.

So, cl_alv_table_create=>create_dynamic_table doesn't work here.</b>

Regards,

Vinod.

check this

FIELD-SYMBOLS :

<lt_data> TYPE table,

lp_table TYPE REF TO data.

Create internal table

CREATE DATA lp_table TYPE STANDARD TABLE OF (p_tab)

WITH NON-UNIQUE DEFAULT KEY.

ASSIGN lp_table->* TO <lt_data>.

Hi .. Check out this...

Sample code :

REPORT ZCLUST1 .

Example: how to create a dynamic internal table
The dynamic internal table stucture

DATA: BEGIN OF STRUCT OCCURS 10,

FILDNAME(8) TYPE C,

ABPTYPE TYPE C,

LENGTH TYPE I,

END OF STRUCT.

The dynamic program source table

DATA: BEGIN OF INCTABL OCCURS 10,

LINE(72),

END OF INCTABL.

DATA: LNG TYPE I, TYPESRTING(6).

Sample dynamic internal table stucture

STRUCT-FILDNAME = 'field1'. STRUCT-ABPTYPE = 'c'. STRUCT-LENGTH = '6'.

APPEND STRUCT. CLEAR STRUCT.

STRUCT-FILDNAME = 'field2'. STRUCT-ABPTYPE = 'd'.

APPEND STRUCT. CLEAR STRUCT.

STRUCT-FILDNAME = 'field3'. STRUCT-ABPTYPE = 'i'.

APPEND STRUCT. CLEAR STRUCT.

Create the dynamic internal table definition in the dyn. program

INCTABL-LINE = 'program zdynpro.'. APPEND INCTABL.

INCTABL-LINE = 'data: begin of dyntab occurs 10,'. APPEND INCTABL.

LOOP AT STRUCT.

INCTABL-LINE = STRUCT-FILDNAME.

LNG = STRLEN( STRUCT-FILDNAME ).

IF NOT STRUCT-LENGTH IS INITIAL .

TYPESRTING(1) = '('.

TYPESRTING+1 = STRUCT-LENGTH.

TYPESRTING+5 = ')'.

CONDENSE TYPESRTING NO-GAPS.

INCTABL-LINE+LNG = TYPESRTING.

ENDIF.

INCTABL-LINE+15 = 'type '.

INCTABL-LINE+21 = STRUCT-ABPTYPE.

INCTABL-LINE+22 = ','.

APPEND INCTABL.

ENDLOOP.

INCTABL-LINE = 'end of dyntab. '.

APPEND INCTABL.

Create the code processes the dynamic internal table

INCTABL-LINE = ' '. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field1 = ''aaaaaa''.'. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field1 = ''19970814''.'. APPEND INCTABL.

INCTABL-LINE = 'dyntab-field1 = 1.'. APPEND INCTABL.

INCTABL-LINE = 'append dyntab.'. APPEND INCTABL.

INCTABL-LINE = ' '. APPEND INCTABL.

INCTABL-LINE = 'loop at dyntab.'. APPEND INCTABL.

INCTABL-LINE = 'write: / dyntab.'. APPEND INCTABL.

INCTABL-LINE = 'endloop.'. APPEND INCTABL.

Create and run the dynamic program

INSERT REPORT 'zdynpro'(001) FROM INCTABL.

SUBMIT ZDYNPRO.
