Hi,

Can anyone please tell me what is the functionality of the FM ' CONVERSION_EXIT_ALPHA_INPUT '.

Regards

Hi Santosh,

To remove leading zeros and leading blanks, use FM :

CONVERSION_EXIT_ALPHA_INPUT Conversion exit ALPHA, external->internal

CONVERSION_EXIT_ALPHA_OUTPUT Conversion exit ALPHA, internal->external

For ex :

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

input = wf_version

IMPORTING

output = wf_version.

Example:

input = 123

output = 0000000000000...000000000000123

Hope this resolves your query.

Reward all the helpful answers.

Regards

It is well documented.

Check this:

Conversion exit ALPHA, external->internal

ALPHA conversion is used especially with account numbers. During conversion from the external to the internal format, the system checks to see if input in the INPUT field is purely numeric, that is, if this input consists only of numbers, possibly with spaces before and after them. If this is the case, then the number string is inserted right- justified in the display field OUTPUT and all spaces to the left of the value are filled with zeroes ('0'). If the input is not purely numeric, it is inserted in the display field from left to right and all extra spaces are filled with blanks.

Example:

(Input field and output field are both eight characters in length)

1. '1234 ' --> '00001234'

2. 'ABCD ' --> 'ABCD '

3. ' 1234 ' --> '00001234'

Conversion from the internal to the external format (function module CONVERSION_EXIT_ALPHA_OUTPUT) is undertaken in exactly the opposite manner.

Usage:

call function 'CONVERSION_EXIT_ALPHA_INPUT'

exporting

input = v_input

importing

output = v_output

exceptions

others = 1.

Hi,

CONVERSION_EXIT_ALPHA_INPUT ..

This function module converts , say for example MATNR , converts MATNR value to internal format value,

If the external value is a number,then the number string is inserted right- justified in the display field OUTPUT and all spaces to the left of the value are filled with zeroes ('0').

If the input is not purely numeric, it is inserted in the display field from left to right and all extra spaces are filled with blanks.

Example:

(Input field and output field are both eight characters in length)

1. '1234 ' --> '00001234'

2. 'ABCD ' --> 'ABCD '

3. ' 1234 ' --> '00001234'

reward if useful,

Re: Function Module

Former Member — Thu, 19 Apr 2007 05:42:57 GMT

hi,

It is used to convert external account numbers to internal format depending on the number. if the number is purely numeric zeros are added to the remaining spaces on the left side of the number. If the number contains characters spaces are remained as it is.

Example:

(Input field and output field

1. '1234 ' > '00001234'

2. 'ABCD ' > 'ABCD '

3. ' 1234 ' > '00001234'

hi,

CONVERSION_EXIT_ALPHA_INPUT

CONVERSION_EXIT_ALPHA_OUTPUT

These function modules convert the value of an external represntation of a field into an internal format or vice versa.(Meaning for some fields like MATNR, then value which you see is not the way it is stored in the database. The value that you see is the external format, and the value which is stored inside the database id the internal format. These function modules convert the values of such fields from internal to external and vice versa.

for example

The customer number is stored '0001005000' in the database.

...

DATA: WA_KUNAG LIKE KNA1-KUNNR.

WA_KUNAG = '1005000'.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

INPUT = WA_KUNAG

IMPORTING

OUTPUT = WA_KUNAG.

E1BPPARNR-PARTN_NUMB = WA_KUNAG.

E1BPPARNR-PARTN_ROLE = 'AG'.

E1BPPARNR-ITM_NUMBER = '000000'.
