Hi ,

You can populate dropdown values from BAPI using the following steps. I assume you have idea about custom controller.

step1:

Create custom controller.Inside custom controller Bind input value then execute BAPI.

step2:

Now you have value node which is returned from BAPI. After execute BAPI you can find size using the following code. create value node and model node object using the code.

Step3:

<custom controller name>.IRole_ResultNode modelnode=wdContext.nodeRole_Result();

<custom controller name>.IRole_OutputNode valuenode=wdContext.nodeRole_Output();

valuenode.invalidate();

int size=modelnode.size();

Step4:

After find size using loop fetch values from model node into value node.Asume in this value node contains key and value.

for(int x=0;x<modelnode.size();x++){

<custom controller name>.IRole_ResultElement modelElement=modelnode.getRole_ResultElementAt(x);

<custom controller name>.IRole_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setId(modelElement.getKey());

valueElement.setText(modelElement.getValue());

valuenode.addElement(valueElement);

}

step5:

After that bind this value node(Role_Output) into Component controller. Then Bind value node(Role_Output) from component controller into view.

Step6:

Finally bind dropdown UI Element into Role_Output node's attribute(ID).

Hi saravanan,

But in the customcontroller,

Bapi_View_Input input=new Bapi_View_Input();

wdContext.nodeBapi_View_Input().bind(input);

input.setMbrsh(new ); here when I press ctrl+space button am not getting anything, and also in Models->ModelClasses-> I cannot see anything like Bapisfldst,Bapiret2,Bapisflava. However the Bapi.._Input and Bapi.._Output are present. Is this the reason for not getting in input.setMbrsh(new ....)here.

Is this the problem with me Bapis???

Help required,its urgent

Thanks&regards,

Hi Datta,

What are the inputs has to be given?. First you have to known the proper inputs for that BAPI. What is the meaning of Mbrsh?. I thing all BAPI inputs are string. So first you create one string variable then assign values Like;

String mbrsh="Input value for BAPI";

input.setMbrsh(mbrsh);

Like you assign all input parameter then execute BAPI. After getting result from BAPI following above steps.

Kind Regards,
