Hi,

then u can proved inport export parameters and table parameters as per ur requirement.

EX Function Module is:

function ztest_biw.

Hello,

Use the transaction SE37 give a name starting with Z or Y and click on create. It will ask for a function group.

hi,

Procedure

Create a Function Group:

To open the Object Navigator choose from the SAP Menu Overview ® Object Navigator.

From the Object Selection window select Function group, enter FG_Tutorial as name of your function group, and choose Display.

Since the function group FG_Tutorial does not yet exist, the system asks you whether to create it. Confirm with Yes.

Enter a short description and choose Save.

In the window Create Object Catalog Entry choose Local object.

You created a local function group. Before it can receive function modules, you must activate it.

In the object list, use the right mouse button to select the function group FG_Tutorial you just created and choose Activate.

On the next screen choose Continue.

The function group is now active.

Create Global Data:

Within the function group you can declare global data. All function modules of this function group share this global data.

In the Object Selection window open the directory tree Includes and double-click on LFG_TutorialTOP.

Choose Create « Change ( STRG+F1 ) and enter the following data declarations in the tool area:

TABLES spfli.

DATA spfli_workarea LIKE spfli.

Check ( STRGF2 ) and activate ( STRGF3 ) the include file.

Create a Function Module:

Create a function module that reads data from table SPFLI .

If you are not yet in the Object Navigator, choose from the SAP Menu Overview à Object Navigator and display the function group FG_Tutorial .

In the Object selection window, use the right mouse button to select function group FG_Tutorial , and choose Create à Function module.

Enter as function module name XX_RFC_READ_SPFLI and replace XX with the initials of your name.

Enter a short description and choose Save.

The system lists the function module in the object list in a new directory Function modules, and displays it on the right side in the Function Builder.

Select the Attributes tab and under Processing type choose Remote-enabled module.

Select the Import tab and enter in the appropriate columns the names of the import parameters: carrid with reference type like spfli-carrid and connid with reference type like spfli-connid . For each parameter set the Pass value flag.

Select the Export tab and enter in the appropriate columns the names of the export parameters: ex_spfli with reference type like spfli and sys with reference type like sy-sysid . For each parameter set the Pass value flag.

Select the Exceptions tab and enter the exception invalid_data .

Select the Source code tab.

The system copies the entries you made in the other tabs and creates a source text.

Complete the function module with the actual flight data retrieval.

Compare your function with the model solution.

Save the function module ( STRG+S ). When the note on remote-enabled function modules appears, choose Continue.

Check the function for errors ( STRGF2 ) and then activate it ( STRGF3 ).

Test the Function Module:

Choose Test/Execute ( F8 ) or Function module à Test à Test function module.

As import parameter for CARRID enter LH ; for CONNID enter 400 . Leave the RFC target system line empty.

Choose Execute ( F8 ).

The system displays the export parameters EX_SPFLI and SYS in an additional table.

For a detailed display of the data select the value in line EX_SPFLI.

Result

You created a function module and assigned it to a function group.

regards,

Arunsri

In SE37 transaction,in the menu bar Goto - > Function Group - > Create Group.Your Function Group will be created.

Step 2.

Go to transaction SE37.Enter your Z Function module name,your recently created function group name and the description.Press Enter.Now your FM is created.

Step 3.

Enter Export,Import parameters.In the source code tab write the code what you want to write.If any exception write in the exception tab.

Method 2)

First u have to create Function Group.

1.se37~~->Goto~~->Function Group--->Create.

2.Create FM.

3.maintain import /export parameters and tables , exceptions.

4.based on the ur requirement u have to bulid ur logic in Source Code by using there Import parameters and u can pass the results by using Export or table.

5.u can raise error by using exception.
