Using FM, CONVERSION_EXIT_MATN1_INPUT on a select-option

[former_member367551]

Dear forumers,

In my program codes, I have a material number select-option (multiple values are possible) and I will need to make sure that its format is converted to the internal 18 characters number for processing.

For this reason, I am using the FM, CONVERSION_EXIT_MATN1_INPUT. However, I am still struggling to make sure that the output is 18 characters (I can't seem to get this done, especially because material number is a select-option). How may I achieve this properly?

Thanks in advance for all the help here.

As an example, even this (simpler example) does not work:-

DATA:
  v_matnr1(9)  TYPE c,
  v_matnr2(18) TYPE c.

  v_matnr1 = '123456789'.

  CALL FUNCTION 'CONVERSION_EXIT_MATN1_INPUT'
    EXPORTING
      input        = v_matnr1
    IMPORTING
      output       = v_matnr2
    EXCEPTIONS
      length_error = 1
      OTHERS       = 2. 

" V_MATNR2 is still outputted as '123456789'

  IF sy-subrc NE 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

What could have gone wrong here?

why not try

conversion_exit_alpha_input !!!

[former_member367551]

Hi Soumyaprakash,

I tried that much earlier too and it works.

But the FM, CONVERSION_EXIT_MATN1_INPUT was already specified by the functional consultant in the Spec requirements.

I'll have to make sure that this requirement is fulfilled.

[Former Member]

both will any ways work similar this case.

[former_member367551]

The other issue that may arise from using the FM, CONVERSION_EXIT_ALPHA_INPUT is that the user is allowed to enter data of the format MARA-MFRPN (40 characters) into the material number select-option on the report's selection screen.

I'll have to make sure that the data is converted properly, specifically for the 18 characters material number format.

[Former Member]

for alpha_input the parameters is CLIKE ..right?

so use any number of chars you want.

you also can do the same after converting.

[former_member367551]

Hi Soumyaprakash,

Yup, that's right - it's CLIKE.

I'll try this out as well, but I'm just a lil hesitant because the spec clearly specified to use the other FM - CONVERSION_EXIT_MATN1_INPUT.

Thanks.

My dear friend,

TABLES:marc.
SELECT-OPTIONS:s_matnr FOR marc-matnr.

<li>When you define material no as select-option like above by referring to standard table field, If a screen field refers to a domain with a conversion routine, this conversion routine is executed automatically each time an entry is made in this screen field or when values are displayed with this screen field. <li>You can go to domain of matnr and check conversion routine is assigned. So automatically it converts the values entered into internal format . <li>You can check that using like below by putting break point .

AT SELECTION-SCREEN.
  LOOP AT s_matnr.
    BREAK-POINT.
    "Check s_matnr-low value.
  ENDLOOP.

<li>It does not show leading zeroes on the screen but you can see that in select-option table s_matnr. Thanks Venkat.O

[former_member367551]

Hi Venkat,

Thanks for the explanations there. Appreciate it.

I have tried this out. But, I'm still not seeing the leading zeros populated for the material number.

Here's how I did it, with the data inputs as '123456' TO '123460' in the selection screen:-

TABLES:
mbew.
...

SELECT-OPTIONS:
s_matnr FOR mbew-matnr.
...

LOOP AT s_matnr.
  break-point.
" Here, s_matnr-low = '123456' and s_matnr-high = '123460'
ENDLOOP.

The other issue is, the user is also allowed to enter data format of MARA-MFRPN (40 char and its domain does not have a conversion routine) into S_MATNR at the selection screen. This is why I'll need to use the FM explicitly also, right?

Please help once again. Thanks.

[venkat_o]

Hi Tan, <li>You need to call CONVERSION_EXIT_MATN1_INPUT function module explicitly to convert the other values entered in MARA-MFRPN field. Thanks Venkat.O

Hi forumers,

Got this issue resolved and properly tested already.

Thanks for all the help. Appreciate the inputs given here.

This code works for me

TABLES:mara.
SELECT-OPTIONS:so_matnr FOR mara-matnr.

DATA:ra_matnr TYPE RANGE OF mara-matnr.
DATA:wa LIKE LINE OF ra_matnr.

START-OF-SELECTION.

  LOOP AT so_matnr.
    PERFORM fm_conversion_exit USING so_matnr-low
                               CHANGING wa-low.
    PERFORM fm_conversion_exit USING so_matnr-high
                               CHANGING wa-high.
    wa-option = so_matnr-option.
    wa-sign = so_matnr-sign.
    APPEND wa TO ra_matnr.
    CLEAR wa.
  ENDLOOP.

  loop at ra_matnr into wa.
    write:/ wa.
  endloop.

FORM fm_conversion_exit  USING    p_so_matnr
                         CHANGING p_wa.

  CALL FUNCTION 'CONVERSION_EXIT_MATN1_INPUT'
    EXPORTING
      input  = p_so_matnr
    IMPORTING
      output = p_wa.

ENDFORM.
