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??????

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

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?
08-16-2007 12:56 PM
For classes, do you not need to specify the internal table name.
You will have to hardcode something.
08-16-2007 12:48 PM
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.
