Parameter error

[Former Member]

Hi,

Where can i find the code of the binding of input fields?

I want to execute a bapi, but when i make a method executeBapiX with the parameter in it. the java code gives an error. Now my question is, how can i import a parameter into a BAPI without the I use a inputfield.

Regards

Sven

Hi,

I dint get ur problem clearly.

If u want to bind the input field,Bind a context Attribute and get the value from it and set to the bapi.

Do not bind the model attribute directly.

Here are the steps it will be useful to u for execution of bapi.

Steps:

1. First create an instance for bapi and bind the instance to the bapi node.

Z<bapi name> zb=new Z<bapi name>();

wdContext.nodeZ<bapi name>. bind(zb);

2. Then if u have the import parameter u have to set them by using

The instance of the above bapi.

Zb.set<import parameters>;

3. If the bapi has a table parameters then the structure for the table parameters will also be imported

In the model class.

4. Set the table parameters by creating the instance for that structure and using this instance set it.

Z<Struct>itm tab=new Z<Struct>();

Tab.set<table parameters>

5. Then add the structure instance to the bapi instance.

Zb.add(Tab);

6. Then Execute the bapi after setting the import parameters.

7. If there is any export parameters, then get the values after execution.

Best Regards,

what exactly is not clear? What i want is very simple i think.

I want to bind the input parameter without using a input field.

[vijayakhanna_raman · Accepted solution]

Hi,

If u want the user to set the import parameter then an ui Element is needed .

Without an UI where u wil bind the imput parameter.

And moreever u cant bind the input parameter directly to

input field u need an context att for it.

And ur senario is not achievable.

What java error ur getting?

well, there is nothing happening. what i want is that:

I have a bapi which has an input parameter. The bapi needs to be launched at starting up the WD. I copied the code downstairs. somewghere in this code i need to fill in the inputparameter pernr (personnelno) so it activates the bapi

at the view i used the following code

public void wdDoInit()

{

//@@begin wdDoInit()

wdThis.wdGetProcesStartController().executeY_Tf_Employeedata_Input();

//@@end

}

In the controller:

Y_Tf_Employeedata_Input input4 = new Y_Tf_Employeedata_Input();

wdContext.nodeY_Tf_Employeedata_Input().bind(input4);

public void executeY_Tf_Employeedata_Input( )

{

//@@begin executeY_Tf_Employeedata_Input()

try

{

wdContext.currentY_Tf_Employeedata_InputElement().modelObject().execute();

wdContext.nodeOutput3().invalidate();

}

catch (Exception ex)

{

ex.printStackTrace();

}

//@@end

}

[vijayakhanna_raman · Accepted solution]

hi,

Write like this.

public void wdDoInit()

{

//@@begin wdDoInit()

Y_Tf_Employeedata_Input input4 = new Y_Tf_Employeedata_Input();

wdContext.nodeY_Tf_Employeedata_Input().bind(input4);

input4.setpersonnelno("String xx");

wdThis.wdGetProcesStartController().executeY_Tf_Employeedata_Input();

//@@end

}

Take the first two lines in the controller.

Hope this helps.

The personell number is comming from an other BAPI Y_Tf_Employeelist_Input, this is a search engine. the result table should trigger the bapi Y_Tf_Employeedata_Input and the Personell number of the selected item should be the input parameter to trigger Y_Tf_Employeedata_Input

[Former Member]

Hi S.

which type (in ABAP) is this bapi parameter personnelno?

regards

Bogdan

[Former Member]

the abap type is persno and the fieldname is pernr

[vijayakhanna_raman]

Hi,

Set it as pernr.

Or Find what is the import parameter that u should give

From the context of webdynpro Expand the Y_Tf_Employeedata_Input node and see the input parameter.

Regards,

Vijayakhanna Raman.

[Former Member]

I did and then i got the error message above

[Former Member]

hi,

I think that this errormessage:

com.sap.aii.proxy.framework.core.DataAccessException: Type conversion error, field PERNR, complex type class

suggest that the convertion from string to personalnumer is not possible.

Could you check please, if exist a special class for parameter personalnumber in your project node: Web Dynpro->Models-><your model name>->Model classes

and when this class exist then use this type in context property which you bind to input parameter.

Regards

Bogdan

[Former Member]

The input parameter should come from Y_Tf_Employeelist_Input and on lead select he needs to get the parameter Pernr and use this parameter to execute the bapi Y_Tf_Employeedata. both Bapi's have in the properties Persno(type) and Pernr (name). For both bapies I used the same code

public void wdDoInit()

{

//@@begin wdDoInit()

Y_Tf_Employeedata_Input input4 = new Y_Tf_Employeedata_Input();

wdContext.nodeY_Tf_Employeedata_Input().bind(input4);

input4.setPernr("String xx");

//@@end

}

public void executeY_Tf_Employeedata_Input( )

{

//@@begin executeY_Tf_Employeedata_Input()

try

{

wdContext.currentY_Tf_Employeedata_InputElement().modelObject().execute();

wdContext.nodeOutput3().invalidate();

}

catch (Exception ex)

{

ex.printStackTrace();

so the input parameter Pernr should come from the search result view and should fill bapi Y_Tf_Employeedata data
