Importing parameters in Function Module SD_VBFA_ARRAY_READ_VBELV
Hi All,
Please let me know the use of importing parameters in the Function Module SD_VBFA_ARRAY_READ_VBELV.
The importing parameters are,
I_BYPASSING_BUFFER
I_REFRESH_BUFFER
I'm having problem of memory overflow in the function module so I thought these importing parameters may help me.
Kindly explainn me the use of these importing parameters and tell me whether they help m out to avoid memory overflow problem.
Thanks a lot in advance,
Rama Krishna
Hello Rama
If you bypass the buffer the fm will always read directly from the DB.
And if you refresh the buffer the buffer is cleared and will be filled again with every call of the fm.
Regards
Uwe

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,

Validating import parameters in Functin module
Hi Eveyone,
Anybody let me know how to validate import parameters to Function module,
if the sy-subrc not equal to 0, what i have to do.Hi Madhavi,
When you pass some parameters to any Function Module , i.e. Import Parameters, First thing we do is validation.
Check for the respective data lements and validate them, If sy-subrc fails, then throw an exception, or raise an error message, by using standard procedure of structure type BAPIRET2 (For RFC's) or throw any respective error message.
Hope this will resolve your Query.
Reward alll the helpful answers.

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.

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.
SundaresanHi,
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,

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.

Checkbox as import parameter in function module
Hi all,
how to create a checkbox as import parameter in function module,
thnx in advance?? Function modules don't have screens...they do have import, export parameters.
If you look at how "checkboxes" are stored in db tables, you'll see that the previous replies are precisely correct. A check box is a char1 field...it is on when 'X' (ABAP_TRUE) and off when blank (initial)....you would call your FM with an import field of type char1 set to 'X' or set to space, and handle accordingly in your FM code.
If you have a checkbox on a selection screen, then the value of that parameter is either 'X' or space, depending upon whether or not the user checked the box. -
What are the input parameters for Function Module

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.

What are minimum passing parameters for function module CS_BOM_EXPL_MAT_V2
Hi
Im going to use FM: CS_BOM_EXPL_MAT_V2 and I want to only pass WERKS, but when I execute FM is gives exception as CALL_INVALID.
I saw all the Import parameters are Optional, but I think I need to pass more inputs to FM.
Please let me know what are MINIMUM input parameters required to run this FM
ThanksHi
In my requirement, there are range of WERKS and MATNR which has to be given from selection screen, where as In CS_BOM_EXPL_MAT_V2 function module I can only give single value for WERKS and MATNR.
Can any one guide me how can I implement this? -
Dynamic parameters in function module
Hi. I need to write a program that can call various different function modules based on what the user inputs.
For example, if the user chooses "BAPI_USER_GET_DETAIL" I need to then call that function module. There is a list of about 30 functions they can choose from.
I can read in the function interface using FUNCTION_IMPORT_INTERFACE and have got the import, changing and tables parameters being entered in an editable ALV.
Now I just need to work out how to call the function module.
I could spend ages hard coding all the various combinations, but what I would like to do is call the function totally dynamically.
I know this wouldn't work, but this sort of thing:
CALL FUNCTION p_funct
EXPORTING
<imp_1> = <val_1>
<imp_2> = <val_2>.
Has anyone got any ideas?
Thanks a lot,
Dave.Hi. I think you've solved it, thanks a lot.
Just checking it all now, will be back shortly.
Can't believe it was that simple, spent ages looking through SDN and google. I was searching for dynamic function, not bapi, so I missed that posting too.

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.
JeetHi 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.
Cheers

Printing options in parameters of function module of smartforms
HI experts,
i hav a loop inside driver program where for every loop it calls smartform and the printing is continuous. But can any one help me how to control this by not displaying LPD. So that directly i can see the preview after all loop passes
Advanced
thanks
KrishHi,
In this I suggest you to capture the data in the OTF format adn append the details after every LOOP pass and finally after ENDLOOP. Now use this OTF data to display the details in PDF where you have option to save the details and Print the form details.
Pass the below variable as 'X' in the control parameters of the Smartform.
ssfctrlop-getotf = 'X'.
Now capture the OTF data return from the Smartform Function Module in the Importing Parameter "job_output_info" as shown below.
data : wa_otf TYPE ssfcrescl,
it_otf type standard table of ssfcrescl with header line.
*ssfctrlop-getotf* = 'X'.
Loop you Internal_table.
*--Call the Smartform Function Module for Displaying the Details
CALL FUNCTION lv_fname
EXPORTING
control_parameters = wa_ssfctrlop
output_options = wa_ssfcompop
user_settings = k_space1
wa_output = p_details
IMPORTING
job_output_info = wa_otf
EXCEPTIONS
formatting_error = 1
internal_error = 2
send_error = 3
user_canceled = 4
OTHERS = 5.
append wa_otf to it_otf.
Endloop.
*--To display the Smartform the PDF format where thr Printing the Form
*--can be done
CALL FUNCTION 'HR_IT_DISPLAY_WITH_PDF'

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,
SalilShould be straight forward. Here's a sample...
Exporting...
VBSK_E LIKE VBSK
ET_SPLITPROT TYPE VLIKP_T_SPLITPROT
