Indeed you can't access these columns statically (by just writting work area and component name) as they might not be included in the table structure, however you can easily access them dynamically (by providing this component name as a variable). For this you need a field symbol and the approach like


data l_field type string.
field-symbols <field> type any.

l_field = 'FIELD1'.
ASSIGN COMPONENT l_field OF STRUCTURE l_dyn_work_area TO <FIELD>.
<FIELD> = "now put your required value here to fill the 'FIELD1' in your strcture

If still not clear just do search around ASSIGN COMPONENT

Hi,

Here dynamically colums will be create and internal table created for that LFA1 table otherwise.

You can declare the types declaration.

TYPES:BEGIN OF TY_DATA,

LIFNR TYPE LIFNR,

END OF TY_DATA.

DATA: pannnn_ref TYPE REF TO data,

pnnnn_str TYPE REF TO cl_abap_structdescr,

pannnn_wa_ref TYPE REF TO data.

FIELD-SYMBOLS :<psnnnn> TYPE STANDARD TABLE,

<pannnn_wa> TYPE ANY,

<pacccc_wa> TYPE c,

<value> TYPE ANY.

data:dbtab type string value 'LFA1'.

CREATE DATA pannnn_ref TYPE STANDARD TABLE OF (dbtab). "TY_DATA that also we can give

ASSIGN pannnn_ref->* TO <psnnnn>.

CREATE DATA pannnn_wa_ref TYPE (dbtab).

ASSIGN pannnn_wa_ref->* TO <pannnn_wa>.

ASSIGN <pannnn_wa> TO <pacccc_wa> CASTING.

regards.
