Former Member — Thu, 09 Aug 2007 14:21:59 GMT

Hi!

I need to create SPECIAL CONVERSION ROUTINE for conversion of a numeric field, it will be used for MastData transfering.

It is inbound user exit and conversion rule is the following: The receiver field is converted.

What tcode to use for creating such exit and what are the steps? I have never done it before, so do not know how to start.

Will reward,

Please be clear about your requirement, whether you want to implement a user exit or create a conversion routine.

Conversion routine can be given at the domain level.

and for your requirement there is no need to create any conversion exit, use move x to y. statement which will take care of conversions ( if it is the case of just numerics).

Reward points if usefull.

Thanks,

Veerendra.

I need to create a User Exit for let's say changing one character in a string (string consists of numbers, but this is not important).

So as I understand, I have to create simple FM via se37, correct?

If you want to use same routine in multiple places then you can create using Se37 .

if not you need to use that logic into only one place then implement in directly your user exit.

any any case if you create in SE37 then it will be reusablitity.

I have troubles when creating FM via se37, because when I try to create for example FM CONVERSION_EXIT_ZVAKEY_INPUT, SAP does not allow to do it and sais that this name is reserved, even if I try to use other name for FM....

Hi,

Please use naming convention starting with Z* or Y* as Seshu mentioned.

Check this link for step by step creating function module.

does not work out... created Z function group and try to name my FM as ZCONVERSION_EXIT_VAKEY_INPUT, but SAP sais the same and it is blue warning, so even if I press Enter I can not continue...

anyway, I was thinking FM should look like CONVERSION_EXIT_&_INPUT.

& - name of <b>conversion routine</b>.

Maybe is other way to create conversion routine (user exit)?

Hi,

It works fine for me ...

Try this ...

1. Go to SE37.

2. Create new function group start with Z*.

Path: SE37 -> Goto -> Function groups -> Create group -> ....

3. Create new function module start with Z*.

Path: SE37 -> Enter new function module (i.e. ZCONVERSION_EXIT_VAKEY_INPUT) -> Click on create button -> Enter function group to assign and description -> Click on continue button -> ....

Hi,

Another option, you can write an abap program that contains subroutine form.

Add your logic conversion inside the subroutine form and call this subroutine from other program to get the conversion result.


Syntax:
PERFORM form IN PROGRAM prog.

Options: 
1. ... TABLES   itab1 itab2 ... 

2. ... USING    u1 u2 u3 ... 

3. ... CHANGING c1 c2 c3 ... 

4. ... IF FOUND
