How to declare workarea?

[Former Member]

I declared this dynamic internal table as shown:

field-symbols: <tab> type standard table.

What code should I write to declare workarea of my internal table that i declared?

DATA <work area> LIKE LINE OF <tab>.

OR

DATA <work area> TYPE <standard table>.

I tried this code.

field-symbols: <tab> type standard table.
DATA wa LIKE LINE OF <tab>.

But I got this error http://img230.imageshack.us/img230/6861/screenog1.png

How do i solve this problem or should I use other codes?

Hi,

Sorry for my earlier reply. But the table which you defined using field-symbols you must need to assign.

i.e. for eg.

ASSIGN <internal table> TO <tab>.

only after this declaration <tab> become specific table type.

You can define generic work area like below.

FIELD-SYMBOLS <work area> TYPE any.

and now you can use as a work area of the internal table using ASSIGN keyword.

Hi Atish,

I have this input field called IO_TABLE and a button. When the user key in the database name into IO_TABLE and press the button, the records/data in the database will be written out.

So i need to dynamically create an internal table to store the database entered in my IO_TABLE.

Hi,

So you can use the same table name to dynamically create a work area as I shown above.

Define

FIELD-SYMBOLS <work area> type any.

Now use this to dynamically create the work area.

Yes I tried that. But I can't call this workarea when I tried create a table control using wizard. So what other method should I use to display the record of the table I enter at my IO_INPUT?

Hi

Check Below..

TYPES DECLARATION..

BEGIN OF g_ty_conditions,

knumh TYPE konh-knumh,

vakey TYPE konh-vakey,

kbetr TYPE konp-kbetr,

kopos TYPE konp-kopos,

END OF g_ty_conditions .

INTERNAL TABLE

DATA g_t_conditions TYPE TABLE OF g_ty_conditions WITH HEADER LINE .

WORK AREA

DATA g_r_conditions LIKE g_t_conditions .

Hope It Helps.
