Hi Pradeep

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.

Look at this thread for codes

Hi Pradeep,

1. In wdDoInit(), add

<Bapi>_Input input=new <Bapi>_Input();//DECLARE this variable globally

wdContext.node<Bapi>_Input().bind(input);

2. In execute() method,

/**********FOR STRUCTURE*************/

<InputStructure> zh=new <InputStructure>();

zh.setXX("xx");

zh.setYY("yy");

input.set<InputStructure>(zh);

/**********************************************/

/**************FOR TABLE****************/

for(int i=0;i<5;i++)//ADDS 5 ROWS

{

<InputTable> zt=new <InputTable>();

zt.setXX("xx");

zt.setYY("yy");

input.add <InputTable>(zt);

}

/**********************************************/

wdContext.current<Bapi>InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

Hi,

Go through the tutorial to understand how to use BAPI in Webdynpro
