assign component - dynamic field

Hey experts,

I want to do this:

ASSIGN COMPONENT (wa_dd08l-fieldname) of structure  <wa_deleted> to <ls_id>

but the (wa_dd08l-fieldname) is incorrect, I can't put there those parentheses.

The <wa_deleted> is a dynamic field symbol and I need to get the ID from it, I have the fieldname of the ID in wa_dd08l-fieldname, but

I can't use it in ASSIGN COMPONENT, so how could I get the value of the fieldname (wa_dd08l-fieldname) from <wa_deleted>?

Regards,

Robert
