go to transaction code se37

1st u have to create function group starting with Z

for creating function group

goto~~>function groups~~>create group

give package name if it is for ur development then give $tmp

then give any name starting with Z then press F5 or press create then it will ask for function group and short text enter what ever the function group u have created and a short text after that press enter then it wil display an msg as

Function module name is reserved for SAP

Hi,

1) Go to SE37 transaction.

2) Give the Z*name & Press Create, it will ask for function group

3) To create new function grp In same tran SE37 Goto-> Function groups-> Create Give the fn grp name & use it while creating FM.

4) Activate the FM.

5) You can give Import, Export, Tables etc parameters inside the same.

Thanks

Declare the parameter same as the type in FM in calling program and pass this to FM. Same for table also.

Re: function module

Former Member — Tue, 22 May 2007 10:52:31 GMT

Hi,

say you have call to FM

DATA:

lv_guid type crmt_object_guid.

CALL FUNCTION 'CRM_GUID_CREATE'

IMPORTING

ev_guid = lv_guid.

this is called in report program.

in se37 u have to create FM 'CRM_GUID_CREATE'

with exporting parameter lv_guid type crmt_object_guid.

as u say create u get tab exportng u declare lv_guid.

similarly incase if ur program has exporting parameters thn those wud bcome importing for FM.

h reshma can you please help me out with user exit.

Re: function module

Former Member — Fri, 25 May 2007 06:52:41 GMT

Hi,

Use the following procedure to create a function module

1.From the ABAP/4 Development Workbench screen, press the Function Library button on the Application toolbar.

2.Type the name of your function module in the Function Module field. The name must begin with Y_ or Z_.

3.Press the Create button. The Function Module Create: Administration screen is shown

4.Type the name of a function group in the Function Group field. The function group name must be four characters long and must begin with Y or Z.

5.Type an S in the Application field. This field is used to indicate which function area uses the function module. Our functionality is not used by any functional area, it is simply an example, so any choice will do. (S indicates that the function module contains functionality needed by Basis.)

6.Type a description of the function module in the Short Text field. The contents of this field are seen when displaying a list of function modules.

Press the Save button on the Application toolbar.

7.If the function group does not already exist, a pop-up informs you of that fact and asks you if you want to create it. Press the Yes button to create the function group. The Create Function Group dialog box appears. Type a description in the Short Text field and press the Save button. The Create Object Catalog Entry screen appears. Press the Local Object button. You are returned to the Function Module Change: Administration screen.

8.Press the Source Code button on the Application toolbar. The Function Module Edit screen is displayed.

9.Type the source code for your function module. Do not change the system-generated comment lines under any circumstances! Your function module might fail to operate if you do.

10.Press the Save button on the Application toolbar. The message Program xxxxx saved appears in the status bar at the bottom of the window.

11.Press the Back button on the Application toolbar. You are returned to the Function Library Initial screen.

12.If you want to define import or export parameters, select the Import/Export Parameter Interface radio button. Press the Change pushbutton. You are shown the Import/Export Parameters screen (refer to Figure 19.6). Type the names of your parameters in the first column and enter any other desired characteristics for each parameter. When you are finished, press the Save button and then the Back button.

13.Finally, to activate your function module, press the Activate button on the Application toolbar of the Function Library Initial Screen.

Hope this helps.
