Using Function Module RS_CONV_EX_2_IN without a predefined structure

[Former Member]

HELLO,

In a SDN Blog I have seen the FM 'RS_CONV_EX_2_IN' can be used to convert formatted char value to float.

I am trying this FM to convert some data but the final data format does not belong to an existing structure.

I have tried to define within the code but I keep getting a 15 return code (invalid name)

What is wrong? Does this FM need a predefined structure to work?

Here is a code sample:

TYPES: BEGIN OF OUT_PUT_TYPE_STRUC,

value TYPE F,

END OF OUT_PUT_TYPE_STRUC.

lv_tabfield-tabname = 'OUT_PUT_TYPE_STRUC'.

lv_tabfield-fieldname = 'VALUE'.

PARAMETERS lv_value TYPE crm_imp_cell_value OBLIGATORY. u201CCHAR30

CALL FUNCTION 'RS_CONV_EX_2_IN'

EXPORTING

input_external = lv_value

table_field = lv_tabfield

IMPORTING

output_internal = lv_cell_value

EXCEPTIONS

input_not_numerical = 1

too_many_decimals = 2

more_than_one_sign = 3

ill_thousand_separator_dist = 4

too_many_digits = 5

sign_for_unsigned = 6

too_large = 7

too_small = 8

invalid_date_format = 9

invalid_date = 10

invalid_time_format = 11

invalid_time = 12

invalid_hex_digit = 13

unexpected_error = 14

invalid_fieldname = 15

field_and_descr_incompatible = 16

input_too_long = 17

no_decimals = 18

invalid_float = 19

conversion_exit_error = 20

OTHERS = 21.

Thanks

Hi Paul,

Please see the documentation.

The parameter OUTPUT_EXTERNAL must have the technical attributes of the ABAP Dictionary field specified in TABLE_FIELD

Functionality
Converts field contents from an external format (INPUT_EXTERNAL) into an internal format (OUTPUT_EXTERNAL). The parameter OUTPUT_EXTERNAL must have the technical attributes of the ABAP Dictionary field specified in TABLE_FIELD. The field INPUT_EXTERNAL must be a character field. It may have any length, but may not be filled to a greater length than that of OUTPUT_INTERNAL (this leads to the exception INPUT_TOO_LONG).

If you use a structure, you will get an output but no values will be stored.

HI Jovito,

Thanks for your help.

But the out-put variable has the right type.

Here is the complete code that you can try.

I have tried two way for the input param.

Regards,

Paul

DATA lv_cell_value  TYPE f.
DATA lv_tabfield    TYPE tabfield.
DATA lv_value    TYPE char30 value '44,5'.

TYPES: BEGIN OF out_put_type_struc,
              value TYPE f,
       END OF out_put_type_struc.

lv_tabfield-tabname   = 'OUT_PUT_TYPE_STRUC'.
lv_tabfield-fieldname = 'VALUE'.

*PARAMETERS lv_value TYPE Char40 OBLIGATORY.

CALL FUNCTION 'RS_CONV_EX_2_IN'
  EXPORTING
    input_external               = lv_value
    table_field                  = lv_tabfield

    output_internal              = lv_cell_value

    ill_thousand_separator_dist  = 4
    too_many_digits              = 5
    sign_for_unsigned            = 6
    too_large                    = 7

    invalid_date_format          = 9
    invalid_date                 = 10
    invalid_time_format          = 11
    invalid_time                 = 12
    invalid_hex_digit            = 13
    unexpected_error             = 14

    OTHERS                       = 21.

IF sy-subrc = 0 .
  WRITE lv_cell_value.
ELSE.
  WRITE: / 'error ' , sy-subrc.
ENDIF.

Hi Paul,

What I meant to say was that according to the definition of the FM, the Structure table_field has to have a table / field combination that exists in the ABAP dictionary i.e. SE16.

Since it does not exist, you are getting sy-subrc = 15.

Replace the below code.

lv_tabfield-tabname = 'OUT_PUT_TYPE_STRUC'.
lv_tabfield-fieldname = 'VALUE'.

With new code.

lv_tabfield-tabname   = 'PGPL'.
lv_tabfield-fieldname = 'ABSAT'.

Also, change the value of lv_value from 44,5 to 44.5.

DATA lv_value    TYPE char30 VALUE '44.5'.

You will see the output.

4.4500000000000000E+01
