Parameters in exit functions

Hello
We have the need to build an exit function in BPS. I have defined the function module and I have also defined a parameter (which I access throuh IT_EXITP within the function module).
The way we have implemented BPS here requires us to invoke BPS functionality through the API calls. So, for eaxample to call a planning function we use API_SEMBPS_FUNCTION_EXECUTE. My problem is that there appears no where on this API top provide paramter information. Does anyone know if it is possible to call an exit planning function witht he API and give it a parameter ?
Thanks
Cameron

Hi Cameron,
unfortunately it's not possible to pass parameters to a planning function using the API. Try using BPS variables instead.

Parameter Exit Function in Planning Folder

Hi all,
I created the planning function in SEM BPS using exit function. And then I added the parameter exit function 0VERSION to this function. After that, I tried to put this function in the planning folder.
Does anybody know how to put the parameter exit function to the planning folder?
Because I need the user to fill the value of the 0VERSION before they run the function.
I assume this should work as the selection screen.
Currently, Every time I run this function, there is no selection screen or the place that I could fill the value for this field. So, the system always receives no value for this field.
Or Maybe you have another approach to get the user's value without restrict the data before run the exit function.
Thanks a lot for your help,
-Martin Darmawi-

This behaviour is quite normal. You should use different approach.
Parameters in exit functions can be filled in parameter group only and only with fixed values.
You should create a planning variable, put it to the folder and then read value of this variable in your exit function with 'API_SEMBPS_VARIABLE_GETDETAIL' for example.

Attribute value to exit function module

Hello group,
I'm working in a sem-bps project and I have a problem with an exit function, because
I need the function module to read the value of a characteristic's attribute.
I read the standard function module UPF_VARIABLE_USER_EXIT_ATTR: it retrieves the attribute value through the import parameters ITO_ATTR TYPE UPC_YTO_ATTR.
I put this attribute on my exit function but when I check the content of the attribute its always empty. Do you know how I can transmit the parameter from the exit planning function to the function module?
Any input is appreciated, thanks Andrea

Andrea, if you want to fill a variable with the characteristic's attribute of another variable look at the document "HowTo_BPS_VarOfTypeExit.pdf" (i send at your e-mail if you want). It Follows an extract in which it's filled the second variable with the characteristic's attribute of another variable:
Source code: Attribute values
SELECT * FROM /bi0/mbps_produ INTO TABLE lt_chavl
WHERE bps_prodl = ls_varsel-low.
if sy-subrc <> 0.
MESSAGE e026(upc) WITH ls_varsel-low '0BPS_PRODL'.
attribute value not found
exit.
endif.
ls_varsel-seqno = '0000'.
ls_varsel-chanm = '0BPS_PRODU'.
LOOP AT lt_chavl INTO ls_chavl.
ls_varsel-seqno = ls_varsel-seqno + 1.
ls_varsel-low = ls_chavl-bps_produ.
APPEND ls_varsel TO eto_charsel.
ENDLOOP.
In the example above ls_varsel contains the attribute value to provide to eto_charsel (the output table in which you have the result).
I suggest you to debug your application to see how ito_attr is passed to the FM.
Hope it helps.

Unable to retrieve parameters from RFC Function Module

Hi All,
I have created a model for the RFC Enabled function module BAPI_BUPA_CENTRAL_GETDETAIL within my webdynpro program. I am passing parameters to the function module BAPI_BUPA_CENTRAL_GETDETAIL and I have validated that this is being passed correctly by displaying the passed value from the node of the input parameters.
Code used to pass input parameters -
IWDMessageManager manager = wdComponentAPI.getMessageManager();
   try
      wdContext.currentBapi_Bupa_Central_Getdetail_InputElement().modelObject().execute();
      size = wdContext.nodeCentraldataperson().size();
      wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(size));
      wdContext.nodeOutput().invalidate();
   catch(WDDynamicRFCExecuteException e)
      manager.reportException(e.getMessage(), false);
I also see that it returns 1 record by using the code below:
IWDMessageManager manager = wdComponentAPI.getMessageManager();
   try
      wdContext.currentBapi_Bupa_Central_Getdetail_InputElement().modelObject().execute();
      size = wdContext.nodeCentraldataperson().size();
      wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(size));
      wdContext.nodeOutput().invalidate();
   catch(WDDynamicRFCExecuteException e)
      manager.reportException(e.getMessage(), false);
But, when I try to retrieve the value returned it does not fetch that value -
   Bapi_Bupa_Central_Getdetail_Output getdata = wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().currentOutputElement().modelObject();
   Bapibus1006_Central_Person[] getres = new Bapibus1006_Central_Person[size];
   for(int i=0; i<size; i++){
        wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(i));
        getres<i> = getdata.getCentraldataperson();
        //String fullname = wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().nodeCentraldataperson().getElementAt(i).getAttributeValue("Fullname").toString();
        String fullname = getres<i>.getFullname();
       fullname += Integer.toString(i);
        wdContext.currentContextElement().setFullname(fullname);
        wdComponentAPI.getMessageManager().reportSuccess("fullname:" + fullname);
It always returns 0 or null. Can someone please help me with this issue. The BAPI returns values in structure format and not internal table and hence I dont see the issue there as well.
What can be the problem?
Thanks for all your help in advance.
Best regards,
Divya

Nikhil / Srihari,
I changed my code and it now looks like - I am trying get the return value into the context fullname but i still cant get the value although the size of nodeCentraldataperson() is thrown as 1 and the input is being passed correctly as i have validated this in this line of code [wdContext.nodeBapi_Bupa_Central_Getdetail_Input().currentBapi_Bupa_Central_Getdetail_InputElement().getBusinesspartner();]
IWDMessageManager manager = wdComponentAPI.getMessageManager();
   try
      wdContext.currentBapi_Bupa_Central_Getdetail_InputElement().modelObject().execute();
      size = wdContext.nodeCentraldataperson().size();
      wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(size));
      wdContext.nodeCentraldataperson().invalidate();
   catch(WDDynamicRFCExecuteException e)
      manager.reportException(e.getMessage(), false);
     for(int i=0; i <size; i++){
          String name = "FullName: ";
          wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().nodeCentraldataperson().setLeadSelection(i);
          name += wdContext.nodeBapi_Bupa_Central_Getdetail_Input().currentBapi_Bupa_Central_Getdetail_InputElement().getBusinesspartner();
          name += wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().nodeCentraldataperson().currentCentraldatapersonElement().getFullname();
          wdContext.currentContextElement().setFullname(name);
Any idea what could be wrong?
Thanks,
Divya

What are the different types of parameters available in function builder an

What are the different types of parameters available in function builder and where do we use them.

The different type of parameters available in FM are
Import - They are used to pass the values to the function module.
Export- They are used by FM to pass the result back to the calling program.
Changing - The variables are passed to the FM and can be changed during the FM processing.
Tables - Internal tables can be passed to the FM (it works similar to changing parameter).

How to declare Dynamic table in Tables Parameters of a Function Module...

Hi Gurus,
I would like to Know how to declare a Dynamic table in Tables parameters of a Function Module.
so that it should be able to hold any table data ....
I have tried all possible ways of trying to assign fields-symbol like declarations which doesnt allow here ...
plz Dont reply with the basics of creating dynamic internal tables, coz my case is not an Internal table it is FM table parameter declaration.....

Hi,
If you are requirement is to create a function module with tables parameter having a generic line type i.e. no specific line type
just declare it with a name under Parameter name with out specifying the type.
A reference function module with such parameter, i would quote is the standard GUI_UPLOAD/ GUI_DOWNLOAD where the parameters specified under TABLES are generic.
If you want to process the values passed to these parameters in the source code of function module, field symbols would be a preferable option.

Reading Data From a Different Planning Package in a Exit Function

Hi,
Is it possible to read data from a planning level / package other than the package that the exit function was executed with? I want to read data into an internal table from another package and use that data in combination with the data in the current package to create new records. If this is possible sample code for how to read data from a different package would be appreciated.
Thanks!
Mel Waldner

Hi,
As an example lets say you have restricted 0calmonth in your package to 6.2007. In the planning layout to fetch values for 5.2007 (read only), you can take 0calmonth in data columns, and for this column restrict it as 5.2007.
Similarly in Planning functions, you can mark 0calmonth as field to be changed and fetch data for 5.2007.
Hope this helps.

Inserting records in the ABAP exit function (hashed table XTH_DATA)

Hi all,
I want to add records in the logic of an ABAP exit function. Due table XTH_DATA being a hashed table the normal insert or append is not possible.
My logic MUST move the data to a temporary table (ITAB) where the logic is executed (modifying KYF values and creating new records.
In order to quickly get to a result I have solved the problem in an awful way through hardcoding the structure of ITAB to be the same as XTH_DATA is in this specific case.
I would like to know if someone has an exmaple of a nice way to dynamically create an ITAB with the structure of XTH_DATA?
At the end it should be possible to do: XTH_DATA[] = itab[].
Greetings,
Martin

Hi Martin,
the only way I know is to solve this problem with sort of pointers, field symbols. Roughly spoken the idea is you lookup the structure of xth_data in table dd03l. you define an internal table of type any. you loop around your xth_data table and assign the value of each column of xth_table to your internal table. then you do your your adding. Hopefully then you can simply assign xth_data to your itab.

Jürgen

How to access BPS variables in ABAP Exit Function

Hi Experts,
I am using a Exit Function. My BPS variables contain multiple values. I want to trasfer then (may be directly read) to an internal table from where I can loop over then.
Could you please suggest me the code for this?
Points will be awarded.
Thanks in advance,
Shiwesh

Did you try using the FMs API_SEMBPS_VARIABLE_GETDETAIL or Z_VARIABLE_GET_DETAIL for this?

How to access reference data in BPS Exit Function

Hi Experts,
Can any please tell me how to access reference data in BPS Exit function. I am creating a copy function using ABAP Exit Function (Std copy and fox formula doesn't work for my requirement).
Please suggest,
Thanks in advance,
Shiwesh

Hi Deepti,
Thanks a lot for your reply. xth_data contains all the data based on package filteration. Let me explain you,
Say, I have a characteristic char and whose value is 'A', I want to change it to 'B' in my copy function, while keeping the original record with 'A' as well. So now I want my xth_data to contain two records, one with A and other with 'B'. I mean to say from value is 'A' and to value is 'B'. Now my package contains 'B' (the to value) as the allowed value, but not A because in the package I am setting this using a BPS variable. There are two types of variables, one is to variables other is from variable. There could be two scenarios,
1. If I set from varibale in the package: if I do so, I will have the data in xth_data containing 'A' as char value. But in this case when I change it to 'B' and try to save both the records, package won't recognize the record with value 'B' and reject it.
2. If I set to variable in the package: In this case the xth_data itself will not contain anything and I can not loop over xth_data because there is no record with 'B'. Only record available in the system is with 'A' values.
That is why I am thinking about having reference daya somewhere. I could loop over reference data and then pass it to xth_data. Package will contain to variable so it will allow all my modifications to get saved.
Thanks and regards,
Shiwesh

Reading manual planning function header data in exit function

Hello all,
I would like to know if is there a chance to read header data of a planning function. The planning function is determined by user selection (user choose which value will be in ) and in exit function I then modify the buffer by data which I get by calling RFC on another system.
My problem is that buffer contain all the planning data for whole planning area (it seems) so there is many unnecessary call. How can I get in exit function value specified by user at start of a planning session?
Thank you for your help

Hi,
There's some issue the planning funciton will only read the data specified by the users (variable values).
Check the configuraiton once again.
thanks

Program name zxvau02 are reserved for includes of exit function group

i am facing a problem during user exit.
when i am trying to change the code in function module (va01) in include zxvvau02
an error is occurred 'program name zxvau02 are reserved for includes of exit function group'

Hi,
1. Find the appropriate Enhancement.
2. Enter the ABAP code in the "Z" program within the function module.
3. Create a project.
4. Add the Enhancement to the project.
5. Activate the project.
At the step (2), when I double click on the Include ZX* within source code of the function module to realize the exit, the
system would prompt to create the include. But NO, it always prompt that the name of include is reserved by SAP and I
cannot create it... I entered an access key for the object ...

Menu-exits, Function-exits & Screen-exits

What is Menu-exits, Function-exits & Screen-exits ? explain

Hi,
Why do you need enhancements ?
The standard applications do not offer some of the functionality you need. The R/3 enchancement concept allows you to add your own functionality to SAP's standard business applications.
What are the different types of enhancements ?
Enhancements using customer exits
Customers' potential requirements which are not included in the standard software are incorporated in the standard as empty modification 'shells'. Customers can then fill these with their own coding. Enhancements can relate to programs, menus and screens. Upward compatibility is assured. In other words, SAP guarantees that the jump from the standard software to the exit and the interface which call the exit will remain valid in future releases.
Enhancements to ABAP/4 Dictionary elements
These are ABAP/4 Dictionary enhancements (creation of table appends), text enhancements (customer-specific key words and documentation for data elements) and field exits (creation of additional coding for data elements).
What is customer development ?
Creating customer-specific objects within the customer name range.
What is SSCR ?
SSCR (SAP Software Change Registration) is a procedure, for registering all manual changes to SAP source coding and SAP Dictionary objects.
What is the difference between modifications and enhancements ?
Modifications mean making changes to the SAP standard functionality.
Enhancements mean adding some functionality to SAP standard functionality.
What are the disadvantages of modification ?
Modifying standard code can lead to errors
Modifications mean more work during software upgrades
What are the advantages of enhancements ?
Do not affect standard SAP source code
Do not affect software upgrades
when do you opt for modification ?
Customer exits are not available for all programs and screens within the R/3 standard applications. You can only use exits if they already exist within the SAP R/3 System . Otherwise you have to opt for modifications .
What are the various types of customer exits ?
Menu exits
Screen exits
Function module exits
Keyword exits
What is a menu exit ?
Adding items to the pulldown menus in standard R/3 applications .
13.What is a screen exit ?
Adding fields to the screens within R/3 applications. SAP creates screen exits by placing special subscreen areas within a standard R/3 screen and calling a customer subscreen from within the standard dynpro's flow logic.
What is a function module exit ?
Adding functionality to R/3 applications. Function module exits play a role in both menu and screen exits.
What is a keyword exit ?
Add documentation to the data elements of key words defined in the ABAP/4 Dictionary. The system displays this documentation whenever a user presses F1 to get online help for a screen field.
How do SAP organizes its exits ?
SAP organizes its exits in packages that are called SAP enhancements. Each SAP enhancement can contain many individual exits

Bug in SAP B1PL 42 on validate events and exiting functions

I've recently tested an upgrade to PL 42. There seems to be an issue when trying to exit a function or trying to set return false.
Here is a sample code of what i use to accomplish in previous patches.
Case SAPboiuCOM.BoEventTypes.et_VALIDATE
       Select Case pVal.ItemUID
             Case "matPay"
                    If pval.InnerEvent Then
                         do nothing
                     else
                         Dim oMatrix as SAPbouiCOM.Matrix = oForm.Items.item(pVal.ItemUID).Specific
                         Select Case pVal.ColUID
                                Case "RegHours" : if sglRegHours = oMatrix.Columns.Item(pVal.ColUID).Cells.Item(CInt(val(pval.Row)).Specific.Value then Return False
                         End Select
No matter what I try here, Return False, Exit Function, it does not work. It keeps executing the rest of the code. And yes, the statement gets executed.
Any one else has found something similar to this odd behavior ?
any comments or suggestions would be greatly appreciated
Edited by: Neftali Figueroa on Jan 31, 2008 10:58 AM

Well
I found a workaround for this odd problem. What I did was ... since the evaluation part of the code (if statement) was getting executed right, i changed the statement like this
blnValueEdited = (sglRegHours <> Csgl(oMatrix.Columns.Item(pVal.ColUID).Cells.Item(CInt(val(pval.Row)).Specific.Value ))
and then evaluate the blnValueEdited for true
