Default value for Select-option in Module Pool?

jens_straten2 — Thu, 26 Aug 2010 05:00:19 GMT

I am having a problem with assigning a default value to a select-option in a module pool.

Basically, this works fine for parameters in the PBO, but it simply doesn't work for select-options. From what I can see in debug mode, any default values for select-options are being deleted by the corresponding call subscreen (standard code).

Therefore I tried to set the default value once more after calling the subscreen, but then I have to hit return (screen refresh) to see the actual value as expected. So, this is not a solution either...

Is there a trick? Is it a bug? Did anybody get this to work? Is there a know workaround?

Thanks,

Jens

Hi, Jens

Are you working on Custom or Standard Screen? If it is a Custom Screen then Write Code in AT SELECTION-SCREEN OUTPUT like bellow.

AT SELECTION-SCREEN OUTPUT.
  IF sodate[] IS INITIAL.
    sodate-low = sy-datum.
    APPEND sodate.
  ENDIF.

Thanks and Regards,

Faisal

Kiran,

I have seen this before, but I don't want to use it.

Will give you some points anyhow since it is a good alternative option.

Thanks,

Jens

Thanks Faisal!

Your answer solved my problem.

I simply forgot an append statement... I normally know this, but I guess I tried to accomplish too many things on a single day yesterday.

One more comment:

If you are using ABAP objects like me, you will have to declare a local structure similar to type rsdsselopt (don't forget to adjust high/low fields to your field type) in your method. You can then assign values to -low, -high, etc. before you append your structure to your global select-option.

Cheers,

Jens
