Problem for conversion exit using field symbols

[Former Member]

Hi,

I have to create a varible dynamically and i need to pass that varible for conversion

ie : in my internal table i have matnr , vbeln , kunnr like this it can be any field.

now i need to do a conversion for leading zeros.

but when i pass the <value > to conversion exit it is giving me a runtime error..

for example iam using field kunnr and in the importing parameter if i pass v_kunnr it is giving me result , but if i pass <value> it is giving me runtime error.

PARAMETERS :
     Field_name TYPE fname.
DATA:
wa_ref TYPE REF TO data.

FIELD-SYMBOLS: <level> TYPE ANY.

CREATE DATA wa_ref TYPE (tab_name).

ASSIGN wa_ref->* TO <level>.

ASSIGN '1000' TO <level> .

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
  EXPORTING
    input  = <level>
  IMPORTING
    output = <level>.
.

How can i correct it

Regards

The output parameter of the fm must not be a field symbol.

any alternative to work with conversion exits for different data types.

Hi,

The dump appears because the field symbol assignment gets changed.

Do something like this.

data : tab_name type fieldname.

DATA:
wa_ref TYPE REF TO data.

data : lv_kunnr type kunnr.

FIELD-SYMBOLS: <level> TYPE ANY.

tab_name = 'KUNNR'.
CREATE DATA wa_ref TYPE (tab_name).

ASSIGN wa_ref->* TO <level>.

lv_kunnr = '1000'.    "The field which contains the data ( can be customer or vendor or document etc)

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
  EXPORTING
    input  = lv_kunnr
  IMPORTING
    output = <level>.

Dont assign a constant to field symbol.

You cannot change a constant value.

Instead do it like..

data:field1 type char10 value '1000'.
FIELD-SYMBOLS: <level> TYPE ANY.
ASSIGN field1 TO <level> .
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
  EXPORTING
    input  = <level>
  IMPORTING
    output = <level>.

Hi Kumar I have also got the same error.

actually in function module conversion_exit_alpha input .. in eporting parameters whatever value you are giving it should be assigned with data element of tabname-fldname.

So you can go ahead with this code.

*&-- Convert Numeric data with zero.

concatenate i_table '-' i_fldname into lv_dtyp.

create data value type (lv_dtyp).

assign value->* to <fs> .

call function 'CONVERSION_EXIT_ALPHA_INPUT'

exporting

input = i_fld_value

importing

output = <fs>.

here i_table is the table name and in case of you it is KNA1 and i_fieldname is Kunnr.

this will work for sure.

Let me know if you have any concern.
