Use of Interface parameters in Function module in ECC 6.0

Hello all,
In ECC 6.0 Version we do not use Changing/Tables interface parameters. Instead we declare a table type and use Exporting Parameters.
Can any one send me the link to sap help where this is mentioned.
Thanks,
Salil

Should be straight forward. Here's a sample...
Exporting...
VBSK_E LIKE VBSK
ET_SPLITPROT TYPE VLIKP_T_SPLITPROT
If not enough, do application help from function module....

Interface parameters in Function Module -- Doubts

Hi,
We are developing a custom function group which will have 5-6 custom function module. When you create a function module and specify its Export/Import and table parameters, SAP mark them as "Local Interface".(You can look at the Function module source code's first line)
But if you goto the Menu and click Edit>Interface>Globalize parameter and it will change from "Local Interface" to "Global Interface". So now you can use these interface parameters (Export/Emport or tables) without passing them explicitly in perform statement. So in other words they are easily available in the function module.
My question are:
1. Whats the difference between Local interface and Global interface and when should we use which. (SAP normaly use Local interface in all there function modules).
2. If we use Global interface then is it possible that multiple instances (same fuction module called at same time with different or same data) will somehow mix the data from different calls and show unpredictable results.
Will appreciate if someone can help me understand it from conceptual point of view.
Thanks in advance.
Jeet

Hi Jeet,
1). The difference between Local and GLobal are identified by the name itself. One makes the interface locally available and one makes it globally available. This means that, within the function group, you can access the function parameters in subroutines, as well as PBO and PAI modules.
When to use depends, if your function module consists huge code and does massive processing in such cases its better to write subroutines and split the code into smaller sections for parallel processing. In Such cases its better to use Global interface so that you dont have to pass the interface each and every time.
2). Yes it might affect the gloabl parameters as Unlike other global data, the contents of the global parameters of a function module are known only from the time of the call until you leave the module.
Due to this limitations SAP has come up with OOPS concept where the data integrity is maintained.

How to log input parameters for Function Modules?

Hi,
I need to create a Logging system to trace input parameters for function modules.
The log functionality could be done by developing a class method or a function module (For example 'write_log'), and calling it within each function module that I want to log. The 'write_log' code should be independent from the interface of the Function Module that I want to log.
For example, I'd like to write a function/class method that can log both these functions modules:
Function DummyA
 Input parameters: A1 type char10, A2 type char10.
Function DummyB
 Input parameters: B1 type char20, B2 type char20, B3 type char20, B4 type Z_MYSTRUCTURE
Now the questions...
- Is there a "standard SAP" function that provide this functionality?
- If not, is there a system variable in which I can access runtime all parameters name, type and value for a particular function module?
- If not, how can I loop at Input parameters in a way that is independent from the function module interface?
Thank you in advance for helping!

check this sample code. here i am capturing only parameters (import) values. you can extend this to capture tables, changin, etc.

Here what are the Input parameters for Function Module.
Thanks in Advance.
Srinivasan.

Srinivasan-
For creating a Generic extractor based on a FM, you first of all need to know what is going to be your structure.. i.e. what all fields you need to pull from what all tables. A functional consultant may help you identify the exact DB tables.
Once you know them, hand over the requirement and the pdf mentioned by Krishna to the ABAP guy, he would be able to take this up further.
Also decide 1st whether you would be using a full load or delta. There is a slight difference in the way they are built.
Let me know how it goes.

Need of Changing Parameters in Function Module

Hi All,
Why we need sepearte Import and Export parameters in Function Module if the Changing Parameters
acts as both import and export parameters.
What is the use of using Changing Parametrs in Function Module.
Thanks in advance.
Sundaresan

Hi,
EXPORT PARAMETERS: When u r passing some value to the function, and the parameter will not be changed in the function, we use export parameter. Example: u pass parameter (a : 10) to a function, even after the function has been executed, value of a will be 10 only.
IMPORT PARAMETER: When u require some value back from the function. u do not provide any initial value to the function. Example : u pass a parameter (b: <blank>) to the function, function returns the same import parameter as (b : 20).
CHANGING PARAMETER: When u pass some value to the function and that function may change that value inside function, then changing parameters are used. Example: u pass parameter ( c: 30) to the function as changing parameter and function modifies this variable and return ( c: 50).
Reward points if helpful.

Probelem with passing parameters to function module

hey i am facing a problem to pass the parameters to function module.let me explain.. we cant pass the parameters which we are using in the select option statements directly to a function module called...i just wanna know if there is any way so that i can pass those values to a fnc module while passing it from select options

Hi,
You have to create a table type in SE11..
Check this sample table type PDSMAINT_MATNR_RNG_T...
Then use that table type in the importing parameter of FM..
PT_MATNR TYPE PDSMAINT_MATNR_RNG_T..
For which field you have created select-options..I will check if there is any existing table type in se11..
Thanks,

Pls explain me the use and purpose of following Function modules

pls explain me the use and purpose of following Function modules
1. G_MAX_PERIOD_AND_OFFSET_GET
2. DEQUEUE_E_TABLE
3. FI_COMPANY_CODE_CHECK
4. G_PERIOD_GET
5. alv_display_function
6. G_SET_GET_ID_FROM_NAME
thanks ,
phyrose

1. G_MAX_PERIOD_AND_OFFSET_GET
For given No. of period & periods it gives the offset
2. DEQUEUE_E_TABLE
To Unlock the table records
3. FI_COMPANY_CODE_CHECK
To validate Company Code

4. G_PERIOD_GET
Returns no. of Posting period & Special period for give company code, posting date & ledger
5. alv_display_function -
No such FM exists

6. G_SET_GET_ID_FROM_NAME - Use this module to derive the internal set Id from the name that appears on the user interface, for example, in order then to import the set (see the function group documentation).
The function module first determines a candidate list of sets based on the set name and the class that might have been specified that could match the set name. The class can also be masked (e.g. 000+ for all FI-SL sets, including dynamic sets).

What are the parameters of Function Module

Hi,
What are the parameters of Function Module?

Function Modules are special external subroutine stored in a central library. The R/3 system provides numerous predefined function modules that you can call from the ABAP/4 programs.
All the function Modules are created under the Function Groups. Function Groups are nothing but the related group of function modules.
The function modules can be maintained through T.CodeSE37 and T.Code SE80.
In general the function module has the following components.
Documentation:
This is the place where you can find the discription/purpose of the function module.
Import & Export Parameters.
Import parameters correspond to the formal input parameters of subroutines. They pass data from the calling program to the function module.
Export parameters correspond to the formal input parameters of subroutines. They pass data from the function module back to the calling program.
Table Parameters.
Table parameters are internal tables. Internal tables are treated like changing parameters and are always passed by reference.
Exceptions.
Exceptions are used to handle error scenarios which can occur in the function modules. The function modules checks for any type of error and raise exception and returns SY-SUBRC value to the calling program.
Source Code:
the programming logic of the function module is written in this source code.

Can i use Two DSO 's in Function module

hi experts,
Can i use Two DSO 's in Function module .That FM is used for Layout
I actually want to fill one DSO Refering the Data in Another DSO.
Regard
Naresh.

In the first way the DSO's are usually called shared libraries or DSO libraries and named libfoo.so or libfoo.so.1.2. They reside in a system directory (usually /usr/lib) and the link to the executable program is established at build-time by specifying -lfoo to the linker command. In the second way the DSO's are usually called shared objects or DSO files and can be named with an arbitrary extension

Difference between Import and Export parameters in Function Module

Hi All,
I am unclear about the import and export parameters, when i create a function module. Can anyone explain abt this. However when i call the function module in any program the import parameters in Function module are displayed as exporting in program amd the export parameters as importing.
Any help on this would be appericiated.
Shejal.

HI,
Import parameter in FM is the value u provide to FM for processing.
export is the value u get from FM after processing.
when u call a FM in a progam the import parameter will appear as Export bcos u r giving value to the FM.
and u r getting value from FM in import parameter(bcos u r importing).
rgds,

Put it this way... if you have blueprints for a car you wouldn't want to produce only one car, would you? You would want to produce as many as needed. In another example, you don't want to be able to use only 1 window in Windows. Each window has common features but have different values. That's the purpose of non-static entities
However, there are instances that you want to have only one value for something. That's when you use static entities.
Get it? =)

Is it possble to use out/inout parameters in function?

Is it possble to use out/inout parameters in function?

Hi,
user10784864 wrote:
But I can't call the function from SQL if it contains DML statements also right?Right.
I know of two separate and independent reasons why fucntions with OUT arguments (or IN OUT arguments; I'll just say OUT in the remainder of this message)might not be a good idea.
(1) They can be confusing, and
(2) you can't call them from SQL statements.
My reasons for (1):
They are potenially confusing, because people usially expect the function value (alone) to pass information back to the caller. I like to write code that works. I like to avoid writing code that doesn't work, even if the reason is simply because someone else didn't read the documentation carefully. Notice I didn't say "Never write a function with OUT arguments", I said think carefully before you do. I believe there are good uses for such functions. I also believe that there are good uses for duct tape, and those good uses account for maybe 1% of the actual applications. (By the way, DML in stored procedures is another thing that is done far more often than it should.)
If one of these reasons doesn't apply in your case, you should still consider the other reason.

Function module in ECC 6.0

Hi Experts ,
I have an issue in using Function module in ECC 6.0 , while passing data in table parameter is showing an error as ' Table parameter is obselete'. Can u please suggest any other way of passing table in function module.
<removed_by_moderator>
Edited by: Julius Bussche on Oct 20, 2008 10:35 AM

use table types:
types: ty_struc type ...,
ty_tab type standard table of ty_struc.
data: it_tab type ty_tab.
call function ...
changing it_tab
Don't use TABLES parameters any more, they have implicit header lines, which is a no-no in ABAP Objects context.

Function Module - SAP ECC to BODS

Hi Experts - I have one function module in ECC system which is RFC enabeled and I have imported that in BODS.
Its showing me under function under ECC Data Store.
I am not able to drag it into normal data flow ,,,, Why ?
Is there any special data flow is required to use this.
I want to put the output of this function module in a flat file ? can i achieve this ? so function module to transform and then flat file.
Thanks
R

You need to call the function via a Schema Out function within a Query transform just like you would call a custom function, i.e. right-click in the Schema Out panel and select 'New Function Call' then in the function wizard you must select your ECC datastore from the 'Function Categories' list and then you should see your imported function on the right, then follow the wizard to define the input parameters and choose which output parameters you want output as colums in the query (and can then write to a flat file). Just be aware that if one of the output parameters is a table then you will need to unnest the table schema in a second query transform before wrtiting to the file. Oh and just use a 'Row_Generation' transformation to generate one dummy row as a source.

Error while creating webservice from function module in ECC

Hi
while creating a web service out of a function module in ECC, in the configure service section we get a message saying ' Remember that the service does not have any runtime configuration and therefore cannot be used. Create the Web service configuration in the NetWeaver Admninistrator (transaction WSADMIN2).'
instead of check box 'release for runtime'.
Our ECC at release 7 patch level 22.
Checked in SCICM, SICF teh service and the folder are active.
Please suggest if we are missing on anything
Regards
Kumar

In new version on ECC, the runtime configurations needs to be performed in transaction SOAMANGER.
On executing the transaction, it opens a browser. The important configurations to be performed are:
1. Configure J2EE server and host. You can choose to provide the ECC server and host
2. Administration of the service in "Single Service Administration". The navigation path may differ depending of the ECC versions. But it is related to administration of the services.
Once done, check the WSDL generated.
Use this WSDL in the NWDS.

Sharath
