Re: How to call one webdynpro component to another component

Hi Prabhu,

Fallow below steps...

->component2 view-> methods-> create one method with enable interface.

Bu using the above created method you can pass data from comp1 to comp2.

->double click on comp1 and mention the comp2 in used components.

->In comp1 create one view container..In windows controller select created view container and

embed comp2 ->view.

Now you can get comp2 view into comp1.

-------------------------------------------------------------------------------------

If u want to pass data from comp1 to comp2 we already created one interface method in comp2.

call comp2 method in comp1 like below....

DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.

lo_cmp_usage = wd_this->wd_cpuse_staff_header( ).

IF lo_cmp_usage->has_active_component( ) IS INITIAL.

lo_cmp_usage->create_component( ).

ENDIF.

DATA lo_interfacecontroller TYPE REF TO ziwci_comp2.

lo_interfacecontroller = wd_this->wd_cpifc_comp2( ).

lo_interfacecontroller->method( ).

Re: How to call one webdynpro component to another component

Hi prabhu,

There are so many ways to create method..

But usually these interface methods generated by using serivce calls using BAPIs and

FM...Other wise u can create manually and make that method is interface method.

If u use BAPI and FM their is no need to write the code in side method .Base on BAPI or

FM it automatically generates the code.... I/O parameters are like FM.

Re: How to call one webdynpro component to another component

HI Prabhu,

you can use code wizard to generate code like above then you can compare.

Declare the 2nd component in your 1st component'c component usage & create a usage in the

properties of your view. Then call the method in the required action ( like button to display the second

component).

In code wizard first instantiate the use component :-

Cal the method of the of the 2nd component to pass data

the above code will be generated.

An alternate to above soln you can also make some of the 2nd component node as interface node

and pass data to them from the first one.
