Dynamic access to work area fields

Former Member — Mon, 14 Jan 2008 11:59:12 GMT

I've got a DataBase table with 20 fields with different names.

field1

field2

field3.

....

field20

I'm using a work area to read values and i wanna read an specific field of this work area.

The problem is the following:

I don't know the name of the field i need to access, instead, i have it in a field symbol.

Is there any way i can get the value of this field???

Hi,

Try the following example

DATA: i_TAB LIKE PA0001 OCCURS 0 WITH HEADER LINE,

l_field(50) TYPE C,

l_fieldname(50) TYPE C VALUE 'UNAME'.

FIELD-SYMBOLS: <fieldxx> TYPE ANY,

<valxx> TYPE ANY.

ASSIGN l_fieldname TO <fieldxx>.

SELECT * FROM PA0001 INTO TABLE I_TAB.

LOOP AT I_TAB.

CONCATENATE 'I_TAB-' <fieldxx> INTO l_field.

ASSIGN (l_field) TO <valxx>.

WRITE <valxx>.

ENDLOOP.

Try this,

I am considering 'MARA' as my work area name, <fieldname> as the fieldstring with the fieldname.

FIELD_SYMBOLS : <value> type any.

DATA: fn type string.

concatenate 'MARA-' <fieldname> into fn.

assign (fn) to <value>.

Now the field string <value> will have the required value from the work area's appropriate field.
