how to declare the internal table dynamically?

[Former Member]

I have a requirement to declare an internal table dynamically.

Example

data: itab like (CVDIMENTION) occurs 0.

• here cvdimantion is table name it will vary dynamically

Hi ravikumar,

1.

For this purpose,

in my program,

there is an INDEPENDENT FORM

whose inputs are

TABLE NAME / STRUCTURE NAME

and from those, it consructs dynamic table.

2. Here is the program.

the dynamic table name will be

<DYNTABLE>.

3. U can use this program (FORM in this program)

to generate any kind of internal table

by specifying TABLE NAME .

4.

REPORT abc.

FIELD-SYMBOLS: <dyntable> TYPE ANY TABLE.

FIELD-SYMBOLS: <dynline> TYPE ANY.

use method CREATE_DYNAMIC_TABLE Of class CL_ALV_TABLE_CREATE to create itab at different points in program based on a logic.

How to create a Dynamic Internal Table?

Dynamic Internal Tables

You can put a check depending on your condition you can pass the table parameters to the FM..Ex:-If condition1 is true. Perform gui_upload tables ITAB1.elseif condition2 is true. Perform gui_upload tables ITAB2.endif.Form gui_upload tables ITAB structure ....

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

FILENAME = LDF_FILENAME3 FILETYPE = LDF_TYPE1 HAS_FIELD_SEPARATOR = 'X' TABLES DATA_TAB = ITAB

EXCEPTIONS

FILE_OPEN_ERROR = 1 FILE_READ_ERROR = 2 NO_BATCH = 3 GUI_REFUSE_FILETRANSFER = 4 INVALID_TYPE = 5 NO_AUTHORITY = 6 UNKNOWN_ERROR = 7 BAD_DATA_FORMAT = 8 HEADER_NOT_ALLOWED = 9 SEPARATOR_NOT_ALLOWED = 10 HEADER_TOO_LONG = 11 UNKNOWN_DP_ERROR = 12 ACCESS_DENIED = 13 DP_OUT_OF_MEMORY = 14 DISK_FULL = 15 DP_TIMEOUT = 16 OTHERS = 17 .

IF SY-SUBRC <> 0.

MESSAGE E506 WITH 'UPLOAD' 'SY-SUBRC=' SY-SUBRC SPACE. ENDIF.
