More detail is requested.

Specifically:

What is the goal of your FM?

What will you pass the FM?

What do you expect it to return to you?

hi paul,

What is the goal of your FM?

in a function module there are different interface parameters like import, export, tables,changing etc... in tables parameter t_outtab is used to get internal table , my task is to create a structure for t_outtab which is compactible to my internal table.

What will you pass the FM?

internal table.

What do you expect it to return to you?

nothing, my task is to create a structure for t_outtab and include it in my FM.

thanks in advance....

Hi,

In changing tab fill like this


_*Parameter column                           Type Spec.                      Associated type*_
<Your Internal table Name>                  TYPE                          <Your Table Type Name(ZITAB_T)

You can also fill this in Table Tab also.

Hi,

You have to pass your internal table name only to parameter column you cant pass structure to parameter.

In Tables Parameter you write

t_outtab Type <Table Type>

t_outtab like < Structure type>

Hi,

You just write the parameter name in Table tab. you dont have to declare it anywhere.

When Calling the FM in program u just Pass your internal Table Name to The t_outtab.


CALL FUNCTION 'ZTEST'
    EXPORTING
    i_mtart          =
    i_matkl          =
  tables
    t_outtab      =<your InterNal Table Name>

Hi,

I think it should not give any error. Have u created function group for his?

Try to save it another function group.

1.Then Go to SE80.

2.Select Package from Drop Down Box.

3.Select the Package where u have stored the FM

4.Then Expand Function Group

5.Then Select your Fuction group.

6.Expand That. you will find Include There called L<GroupName>TOP(Eg:LZSANDTOP).

7.Double click on the include it will be in inactive state

8.Click on activate button select all the relevent things try to activate the things at once.

If it doesnot solve your problem, Try to re-create the Fm again from Scratch.
