hi,

Click on Pattern button ( control + F6) , there you can call any FM. Just give the name of FM created in SE37.

Hi saurav,

Do you mean that i can call function module in my webdynpro and then get all the values in an internal table

and use bind_table instance for that node..

I had one more concern.

I am fetching values from the webdyn screen for select options ..

can i transfer this values into table ( s_options ) as we have in abap and pass this in the function module..?

Will this work...?

Best Regards,

Navin Fernandes.

Yes , you can do it this way.

Whatever FM will return , you can get it here also.

can i transfer this values into table ( s_options ) as we have in abap and pass this in the function module..?

You can transfer value to FM just make sure that type of importing parmeters of FM is same as the type you are passing.

You can get the values of these select options and can be passed to the FM to get the data..

hi Navin ,

u create the Function module on the basis of ur existing report and thn use the service call

With the help of the service call function it is possible to call an existing function module from within a Web Dynpro component.

u can use contol wizard ( CONTROL +F7 ) for the same .

refer the related thread :

refer the SAP online help :

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/a189b0ee583b8be10000000a421937/frameset.htm

proceed as follows :

1 right click on ur component and choose Create->Service Call

2 Choice of Controller : choose Use Existent Controller and controller as COMPONENTCONTROLLER

3 for service type choose Function Module.

4 u can choose the required method and context elements ( ir context nodes and attributes under it which are to be used

in ur method)

refer the following demonstration for better understanding and illustration :

Hi,

whne ever you call aBAPI/FM usign the service call it will ask you for teh importing /exporting paremeters as checkboxes then they are created under the nodes of component contronler context..

wehn you get the values from select options into some interna table read them and pass the same to the attribtuesof these importing/exporting nodes of the BAPI by reading the context...you can use the code wizard to set the values to these attirbtues..
