Access column of an internal table dynamically.

[Former Member]

Hi All,

How can I access the column of a table dynamically?

Ex: Data : columnname type string.

columnname = 'name'.

itab-columnname = 'test'.

Kind regards.

Hi Karim,

That is possible through field symbols. Try the following way

field-symbols <fs> type any.

Data : columnname type string,

columnname = 'name',

s_itab like line of itab.

assign component columnname of structure s_itab to <fs>.

Now <fs> Contains the value of the dynamic field 'name'.

Cheers,

you can do some thing like this..

field-symbols: <fs> type any.
Data : columnname type string,
          var(15).
columnname = 'NAME'.
concatenate 'ITAB-' columnname into var.
assign (var) to <fs>.
<fs> = 'test'.

Hi Karim,

It can be using the pointers concept, nothing but Field symbols

You need field symbols

I insert an example of a form using them.

In the example the fields are assigned dynamically
