Conversion Function module

Former Member — Mon, 03 Sep 2007 16:53:21 GMT

Hi Experts,

In my report i need to declare a select-option . This select-option is a combination of Period and fiscal year i..e the values in the select-option should be like

PPP/YYYY period and year need to be separated by "/".

I had declared in that format. Here the period starts from 001-012.So when ever the User enters 010/2005 in low and 007/2007 in high it is giving an error that Lower limit is greater than Higher limit .

For this i had created a Data element with domain that is having a function module

with the folowing code

FUNCTION CONVERSION_EXIT_ZCCON_INPUT.

*"----

""Local Interface:

*" IMPORTING

*" VALUE(REFERENCE) OPTIONAL

*" EXPORTING

*" VALUE(REFERENCE1)

*"----

DATA : L_PPP(3) TYPE C,

L_YYYY(4) TYPE C.

REFERENCE1 = REFERENCE.

SPLIT REFERENCE1 AT '/' INTO L_PPP L_YYYY.

CONCATENATE L_YYYY '/' L_PPP INTO REFERENCE1.

ENDFUNCTION.

but when ever give some data in the selection-screen that is declred with this data element data is not passing to the function module.

I believe your input format should be a number, so you should concantenate only the year and the month into the input:

FUNCTION CONVERSION_EXIT_ZCCON_INPUT.
*"----------------------------------------------------------------------
*"*"Local Interface:
*" IMPORTING
*" VALUE(REFERENCE) OPTIONAL
*" EXPORTING
*" VALUE(REFERENCE1)
*"----------------------------------------------------------------------

DATA :  L_PPP(3) TYPE C,
            L_YYYY(4) TYPE C.

  REFERENCE1 = REFERENCE.

  SPLIT REFERENCE1 AT '/' INTO L_PPP L_YYYY.

  CONCATENATE L_YYYY L_PPP INTO REFERENCE1.

ENDFUNCTION.

FUNCTION CONVERSION_EXIT_ZCCON_OUTPUT.
*"----------------------------------------------------------------------
*"*"Local Interface:
*" IMPORTING
*" VALUE(REFERENCE) OPTIONAL
*" EXPORTING
*" VALUE(REFERENCE1)
*"----------------------------------------------------------------------

DATA :  L_PPP(3) TYPE C,
            L_YYYY(4) TYPE C.

  L_YYYY = REFERENCE(4).
  L_PPP  = REFERENCE+4(3).

  CONCATENATE L_PPP '/' L_YYYY L_PPP INTO REFERENCE1.

ENDFUNCTION.

I think that you MUST name your parameters to conversdion exits INPUT and OUTPUT. I did the following and it works.

1. created a domain znrwperiod....char8....conversion routine znper

2. created a data element using the above domain

3. created function moduleS in the same group as each other

3a. CONVERSION_EXIT_ZNPER_OUTPUT

FUNCTION CONVERSION_EXIT_ZNPER_OUTPUT.

*"----

""Local interface:

*" IMPORTING

*" REFERENCE(INPUT)

*" EXPORTING

*" REFERENCE(OUTPUT)

*"----

DATA : L_PPP(3) TYPE C,

L_YYYY(4) TYPE C.

SPLIT input AT '/' INTO L_YYYY L_PPP.

CONCATENATE L_PPP '/' L_YYYY INTO output.

ENDFUNCTION.

3b. CONVERSION_EXIT_ZNPER_INPUT

FUNCTION CONVERSION_EXIT_ZNPER_INPUT.

*"----

""Local interface:

*" IMPORTING

*" REFERENCE(INPUT)

*" EXPORTING

*" REFERENCE(OUTPUT)

*"----

DATA : L_PPP(3) TYPE C,

L_YYYY(4) TYPE C.

SPLIT input AT '/' INTO L_PPP L_YYYY.

CONCATENATE L_YYYY '/' L_PPP INTO output.

ENDFUNCTION.

Do you think you could close the "Error in Select-Option" thread

where this conversion exit was first suggested? Yes, you have to have INPUT and OUTPUT only defined, as provided in the example code there.
