Calling sub controllers in different BSP applications

I try to call in a controller class a sub controller which belongs to another bsp-application (and another dev package)
Here the example of the structure:
(Package) Z_TST1
--(Controller class) Z_CO_TST1
--(BSP-Application) Z_TST1_BSP
(controller) tst1.do ...
(some additional views, model classes, ...)
(Package) Z_TST2
--(Controller class) Z_CO_TST2
--(BSP-Application) Z_TST2_BSP
(controller) tst2.do
Now i want to call the controller tst2.do as sub controller in controller class Z_CO_TST1. help.sap.com says its possible to call controllers of other applications:
http://help.sap.com/saphelp_erp2004/helpdata/en/21/d8463c9c9ffc3ae10000000a114084/frameset.htm
In controller class Z_CO_TST1 i will do some code like described in help.sap.com:
http://help.sap.com/saphelp_nw04/helpdata/en/ce/43473ccf20514ee10000000a114084/frameset.htm
Thanks for any ideas
Peter

I'm sorry, but I solved it by my own (today). Solution is to let application_namespace empty and use application_name for the BSP application name you call in the create_controller method. In the view I only call <bsp:call comp_id = 'name_of_controller_id' />. Help.sap.com has more info, than I thought.
Thanks for answering - Peter.

Calling of Sapscript program from BSP Application

Hi,
 I have a requirement to display the sapscript output in PDF throgh BSP.
 In the Application program I am taking the output in PDF format.
 Now While calling the Driver program in BSP it is giving dump.
 I am using Submit 'Prog_name' and return.
Pls help.

Hi Thanuja,
You cannot call the program using SUBMIT PROGRAM in BSPs.
You can create PDF from a Smart Form. I have no idea of SAPSCRIPTS calling from BSPs. You can do one thing, you can migrate your SAPSCRIPTS to SMARTFORMS and try the below code.
You can call the the below three FMs in the following sequence.
1)
call function 'SSF_FUNCTION_MODULE_NAME'
 exporting
 formname = l_form_name
 importing
 fm_name = l_function_module_name
 exceptions
 no_form = 1
 no_function_module = 2
 others = 3.
if sy-subrc <> 0.
 message id sy-msgid type sy-msgty number sy-msgno
 with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.
2) call function l_function_module_name
3) call function 'CONVERT_OTF'
Thanks,

To call a wd abap application from BSP use the method CL_WD_UTILITIES=>CONSTRUCT_WD_URL then just create a link in bsp with the url returned like this:
<a href="url">Link</a>
To pass data from wd abap to bsp or vice versa that a look at this blog: /people/koen.labie2/blog/2006/11/29/eating-cookies-with-webdynpro-and-bsp

How to create custom BSP application in SAP CRM?

Hi Experts,
I would like to seek help from you. I am new in developing CRM objects. My first requirement is to create a custom program that will generate a PDF report.
First thing I would like to know is the transaction code where I need to create a BSP application that will be able to run in crm webclient. Please clarify if it is in BSP_WD_CMPWB or in SE80 because it is said that I should create BSP application using MVC.
Second thing is how will I be able to call a smartforms in a BSP application. The scenario for my custom program would be, I should have a two input fields in the selection-screen which are Business Partner ID and Product Lines. together with a button that will trigger the form when ticked.
Hope to hear from all of you. Your help will be very much appreciated.
Thanks and Regards,

Hello MonicAnna,
You can find some information on this page.
(http://help.sap.com/saphelp_nw70/helpdata/en/59/cd7daa07d711d5b66f006094192fe3/content.htm)
And also you dont have to use se80 to create new Bsp appliaction. You can create new application by this transaction BSP_WD_CMPWB.

Hello Eddy,
      I have gone thru ur Blog.
But in this I guess I need from this part -->
C. Generating Own Stats in BSP
C.1. Logging It
If all of the aforementioned tools dont cover what youre looking for, or there are technical/other reasons not
to choose them, then there is only one thing left to do. Write your own stuff. It really isnt that difficult to do
and, if you are confident enough, you can make something that suits your needs 100%. Or as a host in a
Flemish regional TV DIY show always says: What you do yourself is usually done better. Let us see what
you need to do in order to achieve this.
First of all you need data on the browser. This can be done via JavaScript and the navigator object:
appCodeName
The code name of browser (i.e.: Mozilla)
appName
The name of the browser (i.e.: Microsoft Internet Explorer)
appVersion
Version information of the browser (ie: 4.75 [en] (Win98; U)
userAgent
String passed by browser as user-agent header. (ie: Mozilla/4.0
(compatible; MSIE 5.5; Windows 98; Hotbar 3.0))
Platform
The platform of the client's computer. JavaScript 1.2 property. (ie:
Win32)
You probably need some extra information like IP number. This can be done via the
request->get_header_field method.
As such you dont need to retrieve this info every time if you have a single entry point like a login page. Just
put it in a server side cookie. Each new page will read this cookie and save this info together with the page
name, user id, eventual parameters, etc. into the log. Now I talked earlier about the visitor concept. This is
also an ideal place to implement this. If you are only interested in returning visitors with a full day time interval,
you can for example determine whether that user has already used that application. If so, you just increment a
counter. If not, you have to create a new line. This method will also reduce the size of your table.
C.2 Showing It
The only thing you need to do is to analyze and visualize stuff. The analyzing stuff is completely up to you.
The following screen shot is an example where the total number of visitors within a given time frame is shown.
It also shows the number of unique visitors in that same time frame compared to the potential number of
visitors. You might find this of interest if you want to know how many (internal) users actually use your intranet
application. You can couple the user info to the department info and then you can figure out whether
department X or Y is actually using the application.
But I didnot get the actual idea of implementing this in my BSP.
Can you give an explanation for the above ?

Deepu.K

Stateful and Stateless BSP Application

Hi Experts,
I would like to know what a stateful/Stateles BSP Applicaiton means. I read the description given in help file but couldn't get the full idea behind it. Could anyone give a practical example for the same and explain. Thanks.
Regards,
Prabaharan

Hi,A stateful BSP application is executed like a normal SAP transaction, independent of all user interactions - in one single context (roll area). This means that data specified by the user during the application execution or data determined by the application itself is available potentially throughout the entire execution duration of the session.
Since the HTTP protocol itself operates in stateless mode and knows no implicit mechanism to assign independent requests to a common logical session, the BSP runtime uses Session Cookies to group requests into one common session. The name of the cookie is sap-contextid, the validity area is restricted to the URL of the BSP application. This means that a BSP application can be executed within a browser only once at any one time. Different BSP applications can operate in parallel in the same browser. Multiple users/browsers can execute the same BSP application in parallel as often as required.
Advantage
The main advantage of stateful BSP applications is that they are simple to program. As usual, you have access to data determined previously and reading or re-calculating data can often be omitted. For database-intensive applications, this can lead to considerably better system performance compared to a procedure where identical read operations have to be executed for every request.
Disadvantage
This significant advantage is at the same time however a disadvantage the improved runtime is offset by a larger memory requirement. The number of possible parallel sessions in an SAP Web Application Server is restricted not least by the amount of available memory space. When this space is exhausted, no further sessions can be started and users cannot log on
Stateless BSP applications only block resources on the SAP Web Application Server during the time one single request is being processed. When the request has been processed, all resources in particular the application context are returned to the system for use in other requests.
Stateless applications allow - at least from the viewpoint of the memory resource optimal scaling regardless of the number of users. On the other hand, releasing the application context after every request may mean that identical data is read from the database and formatted multiple times. In this respect, the runtime may offset the memory saving. This should be evaluated and analyzed on a case by case basis.
Rule of Thumb: Stateful or Stateless?
As a rule of thumb, it is recommended that Internet scenarios used at the same time by a large number of users operate in stateless mode. Stateful programming is recommended for more complex applications that are used by a limited number of users in parallel and that operate with data that is expensive to determine.
hope this helps.

keerthi.

Calling copy of BSP application in e-recruitment

In E-recruitment module, I have a requirement to copy the SAP standard BSP application HRRCF_REQ_MNT to a z BSP application
and add new fields to one of the BSP pages of the ZBSP application.I could not find any customizing table where I can make a
call to my zBSP application. Can someone help me with this please?

Hello,
to include views of customer bsp application in a container sequence like the requisition maintenance you have to use the standard flexibilization for container sequences.
It can be found in the IMG under the path e-recruiting -> technical settings -> user interface -> (Settings for UI BSP [only 600]) -> Flexibilization.
You first define a context if you have not already done this. Then you go to Container Sequence -> Define Elements for CS and create an element for the screen of the customer bsp you want to include. As the standard customizing is not shown (it's stored in seperate tables) you might want to have a look on T77RCF_CS_ITEM in SE16 to get an idea what to put in the different fields (namespace can be SAP noone seems to know what it's really for).
Then you have to go to -> Modify CS. Add an entry for CS Id 1000 which is the Container Sequence for requisition management. In the assingments you add entries for the context you created before and all customer and standard CS Items you want to use. The elements assigned to this CS Id in standard can be found in table T77RCF_CS_SEQ in SE16.
To access the new configuration you have to call the startpage of the recruiter with the condetext defined (URL Param: rcfContext)

Calling BSP application in same session

Hi,
I am trying to arrange a few BSP pages into some sort of "BSP pool" so I can call them from different applications. Means: I want to create something like a few base objects to re-use in other BSP applications. My BSP applications have to be stateful - so when I embed those pool pages (using iframe or similar technology) I do get a new session and cannot share the model data. :-((
Is there any way of avoiding this session problem? Can I force a call to a new URL (on the same server) to re-use my previous session?
Interface method "IF_BSP_NAVIGATION->goto_page" sports a parameter "session", but this parameter does not what I would have expected when fed with the current session ID.
I could not find any documentation on the session handling in the WAS either. All I learnt is that a new session seems to be created whenever a URL with a different ICF path is called - even on the same server. If this is the case I will definitely have problems pooling BSP pages into a "toolbox" BSP application.
Sharing the model data via server-side cookies could be a way, but fails for object references (like class instances or data references).
Any experience with writing the model data (and references!) into ABAP memory to be re-used in the same GUI session (e.g. CIC)? That might be a workaround (?).
Any hint greatly appreciated.
TIA
Peter

I can tell you what I have used in the pass to acomplish this: BSP Extension Elements or Reusable Controller classes.
BSP Extensions are really designed for just this kind of reusability. You have static interface into and out of the extensions. All the rendering is encosed in the extension, yet will be befored in-line in the rendering of the main page. You don't have to worry about separate sessions, or the overhead of iFrames.
Another very similar approach is to create reusable controller classes. Rendering logic can actually be placed in the controller as well (instead of calling a view). Brian McKellar has an SDN Weblog on how to use a controller class to build a pattern engine.
If you are really trying to create a reusable toolbox - then I highly suggest the Extension approach. However I have done the sharing of model data between two applications. I have an example here:
/people/thomas.jung3/blog/2005/05/27/custom-bsp-extension-element-for-field-level-help
Basically I serialize the model class and write it into a server cookie. Then I pass a unquie ID for that model instance to the second application. It can then retrieve and deserialize the model.

Calling a BSP application from universal worklist

Hi All,
I want to call a BSP application, when a workitem is clicked in Universal Worklist(Enterprise Portal)
I have configured the Task Type in SWFVISU transaction, with Visualization type BSP standard & in visualization parameter i entered,
APPLICATION = zgelrbsp0001
PAGE_ID = leso.htm
When I click on the workitem my test BSP application is called. Buy my requirement is not call a static dynamic application, when the workflow is called the workflow container has a URL
http://dev01.abc.gov.sg:8000/sap/bc/bsp/sap/hap_document/document_port_wf.htm/
this URL will change. But I don't know how to configure to call the URL in container. Please let me know how to achieve this.
Regards,
H.K.Hayath Basha.

Hi Raja,
Thanks for the reply.
I said wrongly in my earlier mai, my URL is static, but the parameter appl_id will have different value.
http://dev01.abc.gov.sg:8000/sap/bc/bsp/sap/hap_document/document_port_wf.htm/?appl_id=1234
What I have done is similar to the one which you have said, copied the standard BSP and modified, I pass WORKITEM ID to the BSP application, BSP application reads the workflow container for appl_id and sets that value to the BSP application attribute.
There should be a better way to do this.

H.K.Hayath Basha.

How to call BSP pages from a BSP application of another package

Hi,
I have a BSP application in one package and I want to call pages from another BSP application in a different package.
Is it possible? How it would have to do it?
Thanks in advance
Regards

Hi,
You cannot call a page fragment in a seperate window or seperately in the same window...
Page fragment is used only for including a fragment in your page....
It is not a seperate page..!
To call a page fragment, you have to use the include directive...
eg :
<%@include file="Carrier_report_logo.htm" %>
Hope this helps.
Do reward each useful answer..!
Thanks,
