Call SAP function from BSP
Hi BSP Gurus,
I am new to BSP World.
I was told that review the existing BSP module and modify the SAP function module to take care of the new business unit.
Now my question is where to start ?....do I need to know the existing BSP module ? How would I know what SAP function is being called from BSP ?
Please help.
With regards,
Pranav
calling Function module is same in ABAP & BSP..there is no difference..Look at the layout or any one evenings (Under event Tab) for CALL FUNCTION '...'..
Since you are new to BSP look at the below links:

Calling SAP Transaction from BSP
I wonder whether it is possible to call SAP transaction from BSP application and pass to it some data; e.g., PO# when calling VA02?
The called transaction could appear in a separate MS IE Window (like in some Portal applications) or in SAP GUI.
Any help will be appreciated.
Thank you in advanceI have launched the Java SAPGui from BSP pages before. I used SNC so that the users were logged on via Single Sign On. I store the Java Gui in the Mime directory. You can force the startup transaction. Theorectically you could also Gui Scripting to try and control the Gui and force in the default value for your PO field. I have not tried that however. You will probably want to check the Service Marketplace for documents on the Gui Scripting. The following is the code from my BSP page to launch the Java Gui in the Browser as an applet:

Hi all,
I need to call a read text function in SAP system, from OWB, this function decrypts the values in the table. The data is not confidential its just that the SAP uses this feature to save some space.
How do I call a SAP funtion from OWB. I am using OWB 11.2Hi Ralf,
try substituting following code:
' the following values are just examples
myStructure("ARCHIV_ID") = "01"
myStructure("ARC_DOC_ID") = "1234567890123457890"
myStructure("AR_OBJECT") = "TIF"
myStructure("DOC_TYPE") = "FIIINVOICE"
myStructure("BARCODE") = "1"
myFunction.Exports("DOCUMENT_ENTRY") = myStructure
with that one:
Set myStructure = myFunction.Exports("DOCUMENT_ENTRY")
' the following values are just examples
myStructure.Fields("ARCHIV_ID") = "01"
myStructure.Fields("ARC_DOC_ID") = "1234567890123457890"
myStructure.Fields("AR_OBJECT") = "TIF"
myStructure.Fields("DOC_TYPE") = "FIIINVOICE"
myStructure.Fields("BARCODE") = "1"

Call SAP function from VB - Structure member not found " unknown "
Hello,
(I don't know if this is the appropriate forum, but I didn't find any which seem to match my topic ...)
I use the following VB code to call the SAP function ARCHIV_PROCESS_RFCINPUT:
Dim bapiControl As SAPBAPIControl
Dim logonControl As SAPLogonControl
Dim functions As SAPFunctions
Set bapiControl = New SAPBAPIControl
Set logonControl = New SAPLogonControl
Set functions = New SAPFunctions
Set bapiControl.Connection = logonControl.NewConnection
' do login
Set functions.Connection = bapiControl.Connection
Dim myFunction As SAPFunctionsOCX.Function
Set myFunction = functions.Add("ARCHIV_PROCESS_RFCINPUT")
Dim myStructure As SAPFunctionsOCX.Structure
Set myStructure = functions.CreateStructure("OARFCIN")
' the following values are just examples
myStructure("ARCHIV_ID") = "01"
myStructure("ARC_DOC_ID") = "1234567890123457890"
myStructure("AR_OBJECT") = "TIF"
myStructure("DOC_TYPE") = "FIIINVOICE"
myStructure("BARCODE") = "1"
myFunction.Exports("DOCUMENT_ENTRY") = myStructure
At this point execution stops with the following error message:
Err.Number: 1006
Err.Description: Structure member not found "<unknown>"
Err.Source: wdtfuncs
What is wrong? The function ARCHIV_PROCESS_RFCINPUT needs one input parameter called "DOCUMENT_ENTRY" which is of type OARFCIN ...
ARCHIV_CONNECTION_INSERT, which has only Strings as input parameters (no structures), works fine ...
I tried all variations I could think of:
myStructure.Value("ARCHIV_ID") = G_csDefaultRepository
instead of myStructure("ARCHIV_ID") = G_csDefaultRepository
declaring bapiControl, logonControl and functions as Object, and instanciating them with CreateObject(...)
myFunction.Exports(0).Insert "DOCUMENT_ENTRY", myStructure
instead of myFunction.Exports("DOCUMENT_ENTRY") = myStructure
(which gave me a "Collection member not found" error) ...
Nothing worked ...
What is wrong with this code??
Thanks for help!

How to call Java API from BSP?
I have a requirement to call Java API from BSP application.
I have checked the forum and found that it is possible by using some ABAP codes.
However there is no pointer on how this is done.
Can someone explain the details on how to call Java API from BSP is done?
I found class CL_EJB_JAVA_OBJECT_METHODS to call a method in EJB but can't find function or SAP class to call Java API.
Actually is there any BSP extention which can used to call Java API?
Thanks,
Hendricheck out these weblogs, it should give you an idea how to go about it.

Hello all,
I dont have much idea of BSP ans would like to have some inputs from you all.
I would like to know that can I call ABAP transaction from BSP page ?
I have got a set of column entries just as an ALV column on my BSP page and I would like to provide hotspot or double click functionality so that for each of the entries in the table , the BSP page navigates to ABAP tcode and back to BSP page.Is this functionality possible?
any help would highly be appreciated.

AmrutaHi Amruta ,
You can't call an R/3 transaction directly from BSP.
But you can achieve all the functionalities it does .
for ex ..if an r/3 transaction is a report , u hav to code in BSP editor .u can call function modules from BSP .
But one thing u hav to concern is ,,in BSP Apllication logic is seperatd from Business logic .
U hav to move all your results into an itab / params and display that inside HTML tables .
Start ur journey from here .......

Calling a function from a DLL, exectution in background mode.
Dear Experts,
We have created an ABAP report the calls a function from a DLL file. If the report is executed in on-line mode the program calls and executes the function from the DLL, but if the ABAP programa is executed in background mode it doesnt calls the DLL function.
Do you know a way to solve the problem when executing in background mode?
Best regards.
AntonioHi Gabriel,
Let me explain in details about my DLL function.
We are importing the business partners from legacy system into the SAP CRM system, so at the moment we created the BP master data via BAPI, I get the name of the BP and this moment I call the function in the DLL file. I export the parameter name and I receive back a simplified string with the name reduced to a code. This code I get back from the dll it is insert in a Z table, so there is no interaction in the screen, all must be executed in background mode, because there are a lot of business partners to be converted in SAP system.
I am sending my code for your considerations.

Calling SAP scripts from WEBDYNPRO
Hi
We need to call SAP scripts from WebDynpro application. As per my understanding we need to do following steps
Create a new RFC function module and create sap script output in PDF format.For this
- use OPEN_FORM , by assigning TDGETOTF='X' in the Options(Structure
ITCPO).
- call function module CLOSE_FORM with option OTFDATA
- convert OTF data to PDF by using function module CONVERT_OTF_2_PDF
Now I would like to know how to display the PDF string from WebDynpro.
Please help....

SujithHi,
You can call by creating external window method.
create LINK to URL or LINK TO ACTION according to requirement, for this. write code in onaction of that.
data: iv_url type string value 'http://<server>:<port>/sap/bc/gui/sap/its/webgui?~transaction=*se38 RS38M-PROGRAMM=rsparam;DYNP_OKCODE=SHOP'.
data: api_component type ref to if_wd_component,
window_manager type ref to if_wd_window_manager,
window type ref to if_wd_window.
api_component = wd_comp_controller->wd_get_api( ).
window_manager = api_component->get_window_manager( ).
window = window_manager->create_external_window(
url = iv_url
modal = abap_false ).
window->open( ).

Two difficulties I can see with this.
First the application seems to allocate the array of references
internally and return a pointer to that array. In that case there must
be another function which then deallocates that array again.
Then you would need to setup the function call to have a pointer to an
int32 number for the deviceList parameter and another pointer to int32
one for the plItems parameter.
Then create another function in your DLL similar to this:
HRESULT WRAPIEnumExtractDevice(WRAPI_NDIS_DEVICE *lpDeviceList, long i,
CHAR lpszDeviceName, LONG lenDeviceName,
CHAR lpszDeviceDesc, LONG lenDeviceDesc)
if (!lpDeviceList)
return ERROR_INV_PARAMETER;
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceName, -1,
lpszDeviceName, lenDeviceName,
NULL, NULL);
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceDescription, -1,
lpszDeviceDesc, lenDeviceDesc,
NULL, NULL);
return NO_ERROR;
Pass the int32 you got from the first parameter of the previous call as
a simple int32 passed by value to this function (and make sure you don't
call this function with a higher index than (plItems - 1) returned from
the first function.

Calling user function from Interface mapping

You have 2 types of calls. SQL and PL/SQL.
To call a function via SQL, it can be done using a the standard cursor interface. E.g.
select MyFunkyFunction from dualIt will return the function value via a single row with a single column. The standard cursor fetch and close cursor calls are used.
To call it via PL/SQL, an anonymous PL/SQL block is needed, and the caller needs to use a bind variable to receive the value from the function. The anon block will look as follows:
begin
:bindVar := MyFunkyFunction;
end;Refer to your client's abstract layer for interfacing with the Oracle Call Interface, on how to deal with bind variables. -
