Customer exit

[Former Member]

Hi Everyone,

In my web application I have one query which contains variable. It is a customer exit variable. When I start the Application this variable are filled with a value from customer exit. Everything works fine. I would like to know if it is possible to call this customer exit one more time after some navigation steps were done.

Ervin,

The following values are valid for I_STEP:

· I_STEP = 1

Call up takes place directly before variable entry

· I_STEP = 2

Call up takes place directly after variable entry. This step is only started up when the same variable could not be filled at

I_STEP=1.

· I_STEP = 3

In this call up, you can check the values of the variables. Triggering an exception (RAISE) causes the variable screen to appear once more. Afterwards, I_STEP=2 is also called up again.

· I_STEP = 0

The enhancement is not called from the variable screen. The call up can come from the authorization check or from the Monitor.

Based on I_Step value user exit will be called before or after variable entry only.

Provide your requirement clearly with example. some one will help.

Hi Srini,

OK some additional explanation:

In my web application I have List Box connected with some characteristic. In this List Box we have for example 4 different values: A, B, C, D. Value A should be always chosen. It means when the user chose B and C, A should be chosen automaticly.

and now my idea with customer exit. If the user has chosen B and C, in customer exit A should be add automaticly. And here is my problem. As I could see, variable with customer exit was called only once at the beginning and not always when I change something in List Box.

Hi.

Exit variables are buffered.

But you can refresh values by setting (command SET_DATA_PROVIDER) OFF and then ON in your dataprovider that contains this variable.

When dataprovider will be set to ON after OFF the user exit variable called and filled again.

Hi Andrey,

I could not find command SET_DATA_PROVIDER. I found only SET_DATA_PROVIDER_PARAMETERS. It is that what you mean?

Hi.

Exactly.

Thx for that idea:

I created the following javascript:

function executeJS_SET_DATA_PROVIDER_PARAMETERS_R( currentState, defaultCommandSequence ){

	var commandSequence = new sapbi_CommandSequence();
	var commandSET_DATA_PROVIDER_PARAMETERS_1 = new sapbi_Command( "SET_DATA_PROVIDER_PARAMETERS" );
    var paramDATA_PROVIDER_TYPE = new sapbi_Parameter( "DATA_PROVIDER_TYPE", "QUERY_VIEW_DATA_PROVIDER" );
	commandSET_DATA_PROVIDER_PARAMETERS_1.addParameter( paramDATA_PROVIDER_TYPE );
		
	var paramINIT_PARAMETERS = new sapbi_Parameter( "INIT_PARAMETERS" );
    var paramListINIT_PARAMETERS = new sapbi_ParameterList();commandSET_DATA_PROVIDER_PARAMETERS_1.addParameter( paramINIT_PARAMETERS );
		
	var paramINITIAL_STATE = new sapbi_Parameter( "INITIAL_STATE", "QUERY" );
	var paramListINITIAL_STATE = new sapbi_ParameterList();

	var paramQUERY = new sapbi_Parameter( "QUERY", "YREWMC01_Q020" );
	paramListINITIAL_STATE.addParameter( paramQUERY );

	paramINITIAL_STATE.setChildList( paramListINITIAL_STATE );
	paramListINIT_PARAMETERS.addParameter( paramINITIAL_STATE );

	paramINIT_PARAMETERS.setChildList( paramListINIT_PARAMETERS );

	var paramTARGET_DATA_PROVIDER_REF = new sapbi_Parameter( "TARGET_DATA_PROVIDER_REF", "DP_1" );
	commandSET_DATA_PROVIDER_PARAMETERS_1.addParameter( paramTARGET_DATA_PROVIDER_REF );
		
	commandSequence.addCommand( commandSET_DATA_PROVIDER_PARAMETERS_1 );

    return sapbi_page.sendCommand( commandSequence );
}

Our query is called: YREWMC01_Q020

Data Provider: DP_1

So is this the right script? Where and when do I have to call this function??

Thanks!

Hi Andrey,

thank you for your Idee but I do not think that it is what I am looking for. If I use it all other selections will disappeard.

Dataprovider will be new initialized.
