Passing value to Work area Column dynamically

[sanjana_lingras]

Hi Experts,

I have a requirement to pass value to work area field and field name will be dynamic.

Below are details :

1. Loop at string

2. split values according to offset and length

3. now first value for field lifnr is available in w_lifnr.

4. Now move w_lifnr to w_itab-lifnr ...........................            here  field lifnr of w_itab will be dynamic. it will vary in each iteration.

How can we change fields of work area dynamically and move respective values?

like w_itab-(w_field)   and w_field will have different value in each iteration like lifnr,vtweg,vkorg etc.

We cannot hardcode these values ,field name of w_itab needs to be passed dynamically.

Is there any way?

Regards,

Sanjana

Hi

You need to upload the defination of the strcuture W_ITAB, you can use the class CL_ABAP_STRUCTDESCR, somthing like

DATA: ABAP_STRUCT TYPE REF TO CL_ABAP_STRUCTDESCR.

ABAP_STRUCT ?= CL_ABAP_STRUCTDESCR=>DESCRIBE_BY_DATA( W_ITAB ).

Now in attribute COMPONENTS you'll have the fieldname of W_ITAB

But how to assign the fields to a certain value depends on your development

Hi Sanjana,

w_itab-(w_field) will not work.

Basically there are two options available.

1.

If w_field had not only the fieldname but tablename as well

like w_field = 'W_ITAB-LIFNR'.

then (w_field) = new_value would work.

2.

using a field-symbol

FIELD-SYMBOLS: <fs_field> type any.

ASSIGN COMPONENT w_field OF STRUCTURE w_itab TO <fs_field>.

<fs_field> = new_value.

Dear Sanjana,

use field symbols.

[sanjana_lingras]

This is not working.

I have the field name but values needs to be moved w_itab-(fieldname).

w_field = 'VKORG'

Now I want move <fs_string> value to w_itab-w_field (*** w_field will change everytime which will have dynamic values)

As Jörg says

you need to use:

ASSIGN COMPONENT W_FIELD OF STRUCTURE W_ITAB TO <FS_FIELD>.

IF SY-SUBRC = 0.

  MOVE <FS_STRING> TO <FS_FIELD>.

ENDIF.
