Get the Variable Name dynamically

[prabhu_s2]

Hi

I want to get the variable name dyncamically. Here is a small example:

Data: T_HeadNr type string.

Data: Var_Name type string.

I want to move the name of the field T_HeadNr i.e. "T_HeadNr" to Var_Name and not the content of T_HeadNr.

any inputs is highly appriciated,.

If you define the fields within a stucture you can use the code

data: i_components type standard table of rstrucinfo.

data w_repid type syrepid.

w_repid = sy-repid.

call function 'GET_COMPONENT_LIST'

exporting

program = w_repid

fieldname = 'ST_RECORDS'

tables

components = i_components.

i dont want this 'ST_RECORDS' to be hardocded. this is my requirement. i need to pass the name dynamically to this f/n module !!!

tell me if this helps

data: begin of myitab occurs 0,
  number type i,
  name(30),
 end of myitab.


data: INT_TABNAME(40).
INT_TABNAME = 'MYITAB'.

* Insert internal table fieldname into itab
DATA : IRSTRUCINFO LIKE RSTRUCINFO OCCURS 0 WITH HEADER LINE.
CALL FUNCTION 'GET_COMPONENT_LIST'
  EXPORTING
    PROGRAM    = sy-repid
    FIELDNAME  = INT_TABNAME
  TABLES
    COMPONENTS = IRSTRUCINFO.

loop at IRSTRUCINFO.
  write:/ IRSTRUCINFO-COMPNAME.
endloop.

write:/ 'end'.

thkx kris for ur reply. but again i dont want any hardcoding such as INT_TABNAME = 'MYITAB'. is it possible to get the name of 'MYITAB' into INT_TABNAME??????

[former_member189059]

MYITAB is the name of an internal table containing the fields

when you ask the program to fetch the fieldnames, you need to tell it from where to fetch it

[prabhu_s2]

there are some classes that gives u the type references of the internal table. in this case is there any similar case where we can get the name of the variable itself?

[Former Member]

For classes, do you not need to specify the internal table name.

You will have to hardcode something.

[Former Member]

You will have to hardcode something. The program cannot assume what structure/field you require.

What is reason you do not want to hardcode the structure.
