how to clear Select options if value of another field is changed

[Former Member]

hi all,

I have a requirement that in selection screen there is a parameter input if some value is provided to this field, f4 help for another select option field will be populated with respect to the parameter input and i have designed like that, i have a problem that if the user changes the parameter value i want to clear the previously selected value in the select options

P1 ='INPUT1'

S1 ='f4 help dependin on INPUT1'

P1 = 'INPUT2'

S1='Old input must be changed'

Regard's

Hi,

You need to change thef4 help for second selct option if the value of 1st one is changed. You will have to refersh the table thats populated to this F4 help.Now ideally in AT selection screen event you can check it ,and populate the internal table again.

COuld you please paste your code here, so we can understand your issue better.

SELECTION-SCREEN BEGIN OF BLOCK invoice WITH FRAME .

ENDIF.

my requirement is that once user has entered the input in both the fields if he wants to change the objectype den i want to field Coursetype

Hi,

BAsically you are fectching object ID On the basis of objecttype. Now do one thing. Pass the value of this otype to a variable.Now In AT selection screen event check the value of this variable with the current value in the sel screen parameter.

IF they are not same, then refresh the Select option for objid here & call the F4 help code block again over here.

[Former Member]

hi, I used

on change of p_objtyp.

refresh s_crstyp.

endon.

still its not getting refreshed

[Former Member]

where are youchecking on change of?

[Former Member]

I am checking it in event

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_objtyp.

[SharathSYM]

Try this,

temp = p_objtyp.

AT SELECTION-SCREEN.

IF p_objtyp nE temp.

REFRESH s_crstyp.

CLEAR s_crstyp.

ENDIF.

It will only effect when user press enter after changing parameter.

Hi,

I am giving just an idea, if it gives reference to the table

1. Define one user define strcture having fields otype & coursetype.

2. Define search help for with otype & coursetype fields with importing fields otype & exporting value coursetype.

3. Attach search help created in step 2 to the structure created in step1.

4. Used these strcture fields in your program.

Note: This logic work only in case of ecc6.0 or higher version, not for 4.7.
