How to read data from field symbol containing Table

Question

I defined a field symbols for reading output of a BRF plus rule however since fielk symbol is of type any
I cannot read its contents
Any inputs are highly appreciated
Please see attachment explaining problem

Answer 1

Thanks a lot for your help
However It did not work for me as it started giving error incompatible types
Here is my code
constants:lv_function_id type if_fdt_types=>id value '3440B5B078B21EE3BC9EB53C42F84A45'.
data:lv_timestamp type timestamp,
      lt_name_value type abap_parmbind_tab,
      ls_name_value type abap_parmbind,
      lr_data type ref to data,
      lv_counter type i value 0,
      lr_target type ref to data,
      lx_fdt type ref to cx_fdt,
      lo_trace type ref to if_fdt_trace,
      lo_lean_trace type ref to if_fdt_lean_trace,
      la_z_string type if_fdt_types=>element_text,
      lv_role_name  type grac_role_name,
      lv_result type string.
field-symbols <la_any> type any.
field-symbols <role_name> type grac_s_od_role_detail.
field-symbols <system> type string.
   types:
    begin of ys_access ,
              role_name type  string,
              system_name   type string,
            end of ys_access .
  types:
    yt_access type table of ys_access .
field-symbols: <access_item> type table,
                <ls_req_access> type ys_access.
data con_name type if_fdt_types=>element_text.
data ls_any type ys_access.
* All method calls within one processing cycle calling the same function must use the same timestamp.
* For subsequent calls of the same function, we recommend to use the same timestamp for all calls.
* This is to improve the system performance.
* If you are using structures or tables without DDIC binding, you have to declare the respective types
* by yourself. Insert the according data type at the respective source code line.
* GET TIME STAMP FIELD lv_timestamp.
* Process a function and record trace data, passing context data objects via a name/value table.
* Prepare function processing:
ls_name_value-name = 'Z_STRING'.
la_z_string = 'P1'.
get reference of la_z_string into lr_data.
ls_name_value-value = lr_data.
insert ls_name_value into table lt_name_value.
* Create the data to store the result value after processing the function
* You can skip the following call, if you already have
* a variable for the result. Please replace also the parameter
* EA_RESULT in the method call CL_FDT_FUNCTION_PROCESS=>PROCESS
* with the desired variable.
