How to access Dynamic deep structure componet?

[Former Member]

Hi all,

My question is here.

Structure A is deep structure.

Structure B is nested in Structure A.

However, a table type C is nested in Structure B.

How complex structure!

user will input the name of A from the screen.

now my code is here.

Data: lref type ref to data.

FIELD-SYMBOLS:<fs_serv> TYPE any,

<fs_logfm> TYPE any,

<fs_lt_data> TYPE ANY TABLE.

create data lref type of (input_name).

assign lref->* to <fs_serv>.

<b> ASSIGN COMPONENT 1 OF STRUCTURE <fs_serv> TO <fs_logfm>.

ASSIGN COMPONENT 1 OF STRUCTURE <fs_logfm> TO <fs_lt_data>.</b>

I think it works, but the 'BLACK' sentences is error.

I cannot access to structure B and table C.

Could any expert to help me with this?

Thank you.

Here you go ......

I am assuming all these are tables.

DATA : T_A TYPE A
DATA : T_B TYPE B
DATA : T_C TYPE c

LOOP AT T_A.
 T_B = T_A-B
* Here you can access B Contents

 LOOP AT T_B.
  T_C = T_B-C.
*Here you can access C contents
 ENDLOOP.
ENDLOOP.

Hi Ravi,

Sorry, I cannot specific A B and C.

Because structure name A is input by user I don't know.

For example, in selection screen.

User will input 'S_Service_Time' or 'S_Service_SLD', etc.

So I have to create data A dynamicly. And then Access to nested sturcture B.

Thanks,

Yan

Can you show the structures in detail, or put the code here.

Hi Ravi,

the sample code works,

but i define the structure in DDIC, not in program

I don't know whether it is the problem.

TYPES: BEGIN OF typ_c,

name(10) TYPE c,

age(2) TYPE c,

END OF typ_c.

data lt_c type table of typ_c.

types: Begin of typ_B,

people like lt_c,

end of typ_B.

types:

begin of typ_a,

company type typ_b,

end of typ_a.

data: lref type REF TO data.

data: name(5) type c.

field-SYMBOLS:

<fs_l1> type ANY,

<fs_l2> type any,

<fs_l3> type ANY TABLE.

name = 'typ_a'.

create DATA lref type (name).

ASSIGN lref->* to <fs_l1>.

ASSIGN COMPONENT 1 OF STRUCTURE <fs_l1> to <fs_l2>.

ASSIGN COMPONENT 1 OF STRUCTURE <fs_l2> to <fs_l3>.

clear name.

This sample is correct. But define the type in DDIC

cause the problem.

Thanks

Hello Ravi,

Thank you for push

I compare the sample code with my actual code.

I found I miss lref<b>->*</b> the 'BLACK' part.

I will give you awards.

Thanks
