Add line to type ref to data field - type table

[Former Member]

HI All,

I have field that is defined as type ref to data ,and the type of it is table with data inside of it lr_data.

I have the also the table type of lr_data and I want to add additional line to the type ref to data field.

How can i do that ?

For example

 TYPES: BEGIN OF bank_list,
         country_key type string,
         bank_key    type string ,
         bank_name   type string,
         bank_city  type string    ,
       END OF bank_list.

data lt_bank type table of bank_list.

data lr_data data  ref to data.

Now lr_datae is  type lt_bank " in _Runtine
and contain 4 entries .

I get the lr_data with 4 entries and I want to add new entry to the table.

How can I do that?

Thanks,

Joy

Joy Stpr,

I do not know if I understand the question but see if code below can help:

TYPES: BEGIN OF bank_list,
        country_key TYPE string,
        bank_key    TYPE string,
        bank_name   TYPE string,
        bank_city   TYPE string,
      END OF bank_list,

      begin of ref_data,
        data type ref to data,
      end   of ref_data,
      ty_t_ref_data type STANDARD TABLE OF ref_data.

DATA:
     lt_bank TYPE TABLE OF bank_list,
     lw_bank LIKE LINE OF lt_bank.

DATA:
     lr_data TYPE ty_t_ref_data,
     lw_data LIKE LINE OF lr_data.

field-symbols:
     <f_bank_line> like line of lt_bank.

lw_bank-country_key = 'BR'.
INSERT lw_bank INTO TABLE lt_bank
          REFERENCE INTO lw_data-data.

INSERT lw_data INTO TABLE lr_data.

loop at lr_data into lw_data.
  UNASSIGN <f_bank_line>.
  assign lw_data-data->* to <f_bank_line>.
  if <f_bank_line> is assigned.
    write: <f_bank_line>-country_key.
  endif.
endloop.

HI Bruno,

The issue here is that I need to add new line (with new bank as you write down )to the table lr_data but its not working .

Thanks,

Please explain the problem with the code you have written, Its really hard to understand what you are asking

HI Bruno,

The issue here is that I need to add new line (with new bank as you write down )to the table lr_data but its not working .

lr_data is not defined as table but type ref to data can have table there during RT this is the problem here .

In your example you define it as table.and when I want to do append i got an error said that lr_data

is not defined as table so i cant use insert/append.

Thanks,

Joy

I hope the below code clears your doubt.

field-symbols:<fs_tab> type any.
field-symbols:<fs> type any.
field-symbols:<field> type any.
data:wf_refl type ref to data.

assign lr_data->* to <fs_tab>. "<--
create data wf_refl like line of <fs_tab>.
assign wf_refl->* to <fs>.

Now assume that <fs_tab> has two fields field1 and field2.

to append a row to <fs_tab>.

do 2 times.
assign component sy-index of structure <fs> to <field>.
if sy-subrc = 0.
<field> = 'ABC'.
else.
append <fs> to <fs_tab>.
endif.
enddo.

HI

I use your code but how I insert all the fields to the same line in the table ?

ASSIGN COMPONENT 'BANK_KEY'  OF STRUCTURE <fs> TO <field>.
  <field> = '123'.

   ASSIGN COMPONENT 'BANK_NAME'  OF STRUCTURE <fs> TO <field1>.
  <field1> = 'My Bank'.

  ASSIGN COMPONENT 'BANK_CITY'  OF STRUCTURE <fs> TO <field2>.
  <field2> = 'My city'.

Thanks,

Joy
