Hi,

How to catch a matchcode event ?

I've got a standard matchcode, but i want to do some treatment when the user clicks on the matchcode.

Thanks

Hi Mayaa

You have to use OVS or Freely Programed.

Check this Component:

WDR_TEST_OVS

Hi Mayaa,

Unfortunately we can't use Search Helps for this.

You have to code it manually.

Hi Mayaa.

You could create a search help exit for the dictonary search help, or copy the

search help and create the exit afterwards. In the exit you can work with data

before the selection takes place.

Have a <a href="http://help.sap.com/saphelp_erp2005/helpdata/en/cf/21ee52446011d189700000e8322d00/frameset.htm">look</a>.

Otherwise you have to programm OVS like Abhimanyu already said.

Hi Sascha,

You can't use search help exit in webdynpro.

in fact, this is my problem, i've got an alv table in webdynpro and each column has a matchcode.

When i use the matchcode on the first line, i get the selected value in my input field, but it disappears as soon as i do smething else. and in the second line, i don't even get the selected value in the input field.

i tried to do a specific matchcode, but it didn't work.

can someone help.

Thanks

Hi Mayaa.

you can use search help exits in Web Dynpro ... the exit is called regardless of

which way the search help is used ... We make use of search help exits in

our project ...

But this does not seem to be what you are looking for anyway.

Hi Mayaa.

Have a look at search help SFLIGHT.

There is a search help exit defined: SAPBC_GLOBAL_F4_SFLIGHT.

Additionaly read the help link i posted above.

But if you define the exit it will be used for all components that uses this search

help. So maybe you have to copy the standard search help. I think you have to

check whether it is usefull for you. Setting up OVS is also not very complicated.

What exactly do you want to achieve when the user clicks the search help button?

When the user cliks on the search help, i want to create a line in the alv table. is that possible ?

Hi.

Thats not possible using search help exits.

But this would be possible using OVS. In the event handler method which handles the OVS event you can access the context node which is reversed mapped to the ALV.

Hi Saccha,

thank you for your help.

i've decided to try to use OVS.

i've added a component use for WDR_OVS, and i implemented an event OVS handler.

but i've got an error : Input help not possible. Component usage OVS_USAGE does not exist.

i'm sure there is something missing in the settings i've made, have you any idea on what is missing ?

thanks

Hi Mayaa.

Did you add the component / controller usage under the properties tab of the view controller where you created the event handler method?

When you want to use interface controllers of used components you always have to declare the usage in the view controllers properties too.

Hi again.

What is the name of the component usage you have defined in the using component?

Is it the same as you have defined in the context on attribute level where you have set up the OVS search help (OVS_USAGE)?

Cheers,

Sascha

HI again.

Yes it's the same name !

I've also tried to add the component usage in the properties tab of my view i had a message 'Only 7 component usages maximum can be defined" !

Hi,

I found the problem : I tried setting up the OVS on a field and it worked.

But it still didn't work on the ALV table. I think you can't use OVS on ALV tables.

has someone already used a standard matchcode / OVS / User defines matchcode in an ALV table ?

thanks.
