Mandatory parameters

Former Member — Tue, 05 Jun 2007 07:44:00 GMT

Hy!

I have to checkboxes. I must choose<b> one</b> . This must be <b>mandatory</b>.

Fot that I have another two parameters. Those are optional.

They must be in the same screen , in the same line, so I made :

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT (3) text-p05 FOR FIELD sb_kks.

PARAMETERS: sb_kks AS CHECKBOX.

SELECTION-SCREEN POSITION 45.

SELECTION-SCREEN COMMENT (13) text-p04 FOR FIELD p_emkey.

PARAMETERS: p_emkey TYPE /bic/azg1e_kks00-/bic/zg1emkey.

SELECTION-SCREEN END OF LINE.

Q1: How can I choose between the tho ckeckboxes , if the first is also in a selection screen as the second, because it has a parameter that must be in the same line as it?

Q1: How can I make the checkbox mandatory ?

Thank you.

Hi,

At SELECTIOn-SCREEN.

IF the Check_box is initial.

Raise the Error message.

Endif.

HI Anda,

I am not quiet clear about Question1 , if would be great if you could provide some more details.

For the second question , check box and the obligatory key words cannot be used together , so you need to check whether the check box is checked in the event

at selection-screen.

e.g. if p_chk1 is the checkbox which is obligatory , then the code will look some thing like this

at selection-screen.
 IF P_CHK1 is initial.
*" Give error message
 endif.

Hope this helps.

Regards

Arun

I tried this :

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN POSITION 45.

SELECTION-SCREEN COMMENT (3) text-p05 FOR FIELD sb_kks.

PARAMETERS: sb_kks AS CHECKBOX.

SELECTION-SCREEN END OF LINE.

AT SELECTION-SCREEN.

IF sb_kks IS INITIAL.

MESSAGE 'Give a value !' type 'I'.

ELSE.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN POSITION 80.

SELECTION-SCREEN COMMENT (13) text-p04 FOR FIELD p_emkey.

PARAMETERS: p_emkey TYPE /bic/azg1e_kks00-/bic/zg1emkey.

SELECTION-SCREEN END OF LINE.

ENDIF.

But I get an error message that in form routines and function modules the selection -screen is not accepted :(.

Suggestions?

Thank you.

The AT SELECTION-SCREEN is a report event and cannot be clubbed with the screen declarations.

You will have to do this:

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN POSITION 45.

SELECTION-SCREEN COMMENT (3) text-p05 FOR FIELD sb_kks.

PARAMETERS: sb_kks AS CHECKBOX.

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN POSITION 80.

SELECTION-SCREEN COMMENT (13) text-p04 FOR FIELD p_emkey.

PARAMETERS: p_emkey TYPE /bic/azg1e_kks00-/bic/zg1emkey.

SELECTION-SCREEN END OF LINE.

AT SELECTION-SCREEN.

IF sb_kks IS INITIAL.

MESSAGE 'Give a value !' type 'I'.

ENDIF.

It is also not possible to code the selection screen parameters in an IF-ENDIF condition. What you can do give an error message if the checkbox is ticked and the parameter is blank.
