Get the Variable Name dynamically

prabhu_s2 — Thu, 16 Aug 2007 11:14:30 GMT

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'.

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

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.

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?

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

You will have to hardcode something.
