using dynamic fieldname while updating work area

[uttam_kumar4]

Hi All,

I am getting data from CDPOS and I have to show this on an ALV . Depending upon which field is changed we have to update that field in work area and other fields should remain same as current from actual table.

How can I use this .

I have to create the work area then append it to internal table.

Thanks & Regards,

Rahul

Hi..

Declare field symbols work as dynamic memory area where you create a pointer to your static memory area. When you update a field-symbol you're going to change the static area (HEAP/STACK memory)

You can move to a work-area and change your data. What's your purpose?

Hope to help

Bye

Hi Roberto,

I am writing this logic but it is not working.

loop at lt_cdpos into lw_cdpos_op.

READ TABLE gt_op_status INTO lw_op_current INDEX lv_current.

             CONCATENATE 'LW_OP_CURRENT-' lw_cdpos_op-fname INTO lv_value_one.

             ASSIGN lv_value_one TO <fs_any_new>.

<fs_any_new> = lw_cdpos_op-oldvalue.

endloop.

but it is not changing value of workarea field LW_OP_CURRENT-FIELDNAME.

Please check.
