Type in "Callable Object" gallery in CAF?

Hello,
I'm trying to follow the doc "Building the Job Application Process - SAP Composite Application Framework v1.1" to build a test process.
My environment is the NetWeaver Sneakpreview 2004s SPS4 on Windows 2003 Server.
sap.com/SAP-JEECOR 7.00 SP7 (1000.7.00.7.0.20060324070000) 20060703235737
sap.com/SAP-JEE 7.00 SP7 (1000.7.00.7.0.20060319012200) 20060703235756
I logged in ad Administrator, and verified that it also has the roles "GP Basic User" and "GP Business Expert".
After I clicked on "Create Callable Object", the next screen only shows 3 lines in the "Type" pane, which are 'Web Dynpro Form', 'Web Pages', and an expandable 'Data forms'.
I'm looking for "content package" and "Web dynpro component" types.
Am I missing something here? The install of the preview went without any errors (at least not on the installer console). I am able to create a Folder, create a new "content package", upload an HTML file into the package, and activate it.
Also, any references to such self guided study guides will be appreciated.
Ye

that was the easiest 10 points I ever received. thank you. so funny, sometimes you work your butts out and get no appreciation. in your case the question and answer was simple but I still get the maximum reward points. what a great return on investment.
Anyway, if your company is a SAP customer or partner, you should have or somebody in your organization should have the login id to service.sap.com. Otherwise go to SDN under the CAF Tutorial Center SAP Composite Application Framework - CAF Tutorial Center [original link is broken] where you should also get enough how-to guides. Enjoy you learning experience with GP!

How to debug WebDynpro callable Objects?

Hi Colleagues,
how can i debug a webdnpro callable object? The NWDS debug wizard always would have an "application" to start a debug session.

Hi,
I haven´t tried with Callable objects, but with CAF applications. I followed the instructions on the following link and I could debug my applications:

Guided Procedures Adobe form callable object GRANT POINTS!!!!

Hi,
I am trying to add Adobe form to the GP. I created a simple form template .XDP which contains only two element to test in GP
I created CO no problem based on XDP.
When I am trying to preview my GP I see the following functional error :
No activity is currently selected
or if the CO is attached to the first block for execution this one:
The next activity is not yet available: try again later using the "Refresh" button
Any Ideas ?
Any other COs including WD app COs and other types of callable objects in the same GP work just fine
Thanks
Denis

Hi Satya,
Thanks for your reply.
I got my mistake with the help of my colleague.
I had missed to add the below code in wdDoModifyView. It now works well :
Code I added is this -
IWDInteractiveForm iForm1 = (IWDInteractiveForm) view.getElement("InteractiveForm");
iForm1.setDynamicPDF(true);
Thanks,

Callable object for WD java

Hi Experts,
I am new to GP, and i need your help to design my GP.I am a web dynpro developer . I want very basic process to be implemented through GP as follows
1) Employee gets a UI screen for filling some requisition form (in WD java) which wud hit R3
2) Employee's supervisor can Approve / Reject requisition . (UI in WD JAVA)
3) Employee should get a summary of whole process (Again UI in WD JAVA).
When i am creating calling object for above process and under UI category there are two different type of callable object for wd java
1 ) Web dynpro component (GP interface)
2) Web dynpro application
when i am creating ( Web dynpro application ) callable object , its giving me error , maybe some config problem .
can anyone just guide me how to implement above process or give me some material through GP (WD java UI) and whats diff between two kinds of callable object.Thanks in advance.
Regards,
Abhay

Hi Abhay,
You can design your process by this way:
1) Employee gets a UI screen for filling some requisition form (in WD java) which wud hit R3
If you need to update R3 at this time, you can create a custom WD Java calling a RFC. To do that, you may use WD with GP API (https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59 ) or you may call your RFC directly by External Service Callable Object (https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/7c313ada-0c01-0010-dfba-9ac88b353a47). It depends of how you will design your process.
IE:
Custom WD Screen that will have input fields and will update R3 -> use GP API
Standard input screen -> use Data Input Form and to update R3 use External Service CO
2) Employee's supervisor can Approve / Reject requisition . (UI in WD JAVA)
You can use Visual Approval standard Callable Object to do that. If you need to update R3 according with approval results, you can insert the External Service CO as next step according with result. To accomplish that you must set Result States.
3) Employee should get a summary of whole process (Again UI in WD JAVA).
Data Display Form standard Callable Object give you exactly what you want.
Scenario 1: WD Custom UI that update R3 -> Visual Approval CO -> Data Display Form
Scenario 2: Data Input Form -> Visual Approval CO -> External Service CO -> Data Display Form

Difference between Callable Object for execution and Display

Hi,
I am new to Guided Procedures.When i am creating a callable object under an Action ,i find callable object for execution and callable object for display in the dropdown.What is the difference between the two types of callable objects.
Thanks,
Bala

Hi Bala,
GP comes with a set of registered callable object types that define which applications you can directly expose as callable objects and enable their handling in the context of GP processes.
So the different COs can handle your specific application requirements or process flow requirements appropriately at runtime.
You refer those COs in actions. To make the action functional, you attach at least one callable object to it. In addition to the object that is executed when the action is called, you can attach a callable object that is displayed after the execution. The first one is mandatory. You must attach a callable object for execution. It can be either a callable object with a visible part, such as a Web Dynpro or BSP callable object, or one for background execution.
Optionally, you can attach a callable object for display. It is required to have a visible part for example, you cannot select a callable object for background execution.
At runtime, this object is displayed if the processor wants to open the process step after it has been completed, or if a process contributor has view permissions on the action.
To make it easier, I will give you an example with submitting and approving a composite form. Say, the employee fills in an order for something, submits it and the manager then approves or rejects it.
First, in order for the employee to view the form, you can use a Form Display callable object as a display callable object for actions where the execution object is a form. It displays the name and description of the form and provides a link for download. If the user has view permissions on the step, he or she can view the display object and download the form itself. So, this CO is connected basically with the user experience and what he/she sees displayed on the screen, no matter what happens in the background (e.g. you can have a pre-filling service in the background that prefills some fields of the form, but what the user sees is only the form fields with certain info already prefilled in them).
Next, for the manager to approve or reject the form of the employee, you need a CO that is only for execution, for example a Process Control CO for File Approval For forms, you can use it in a process in which a form is sent by e-mail. As soon as the form is submitted back to the system, the receiver can view it, save a copy of the form, and depending on his or her decision, can approve or reject it.
This really is a very simplified example, but I hope it helped a little in some way or another
Here is a link to the Callable Objects in GP documenatation, hope it also clears up some questions:

Problem in creating a callable object of type Business Logic

Hi SDN,
I am trying to create a callable object of type Business Logic in CE.
When I give all information and click Next, I get this error message.
Error while loading configuration dialog: Failed to create delegate for component com.sap.caf.eu.gp.ui.co.CExpConfig. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
Can anybody help me out with this problem.

Sumangala

Hi.
I'm having the same problem as Senthil in NW2004s SP15 with my application service and methods not showing up in the Callable Object wizard for Composite Application Services after I choose the Endpoint. The only application name that shows up in the wizard is caf.tc, and the only service names that show up for it are LDDataAccessor, Metadata, and PropPermissionService.
My IDE is on one machine and the application server I deploy to is located on a different machine. My endpoint to the remote application server looks to be correctly configured. The Composite Application Service seems to be deployed properly as I'm able to see it and test that it works in the Web Services Navigator <http://remotehost:50000/wsnavigator/>
My deployed application service is a remote enabled service and is also web services enabled as well.
I'm not sure if this is relevant, but I noticed that the generated Java code does not create any remote EJB interfaces (only home and local interfaces were generated).
Something else I noticed is that when I proceed to the External Service Configuration -> Business Entities screen <http://remotehost:50000/webdynpro/dispatcher/sap.com/cafUIconfiguration>, I only see three business entities displayed, and the following error message is displayed: "Corrupt metadata has been detected. This may prevent some objects from being displayed. Check the server log for more details." I was unable to find anything in the instance log files. Is the error message indicative of the problem?
I am developing locally without a NetWeaver Development Infrastructure (NWDI) in place.
I'm wondering if the credentials specified in the endpoint require any special roles or privileges.
Senthil, do any of these additional descriptions apply to you as well?

Error in creating Callable object of type Portal iView

Hi People,
I need to create a callable object of type Portal iView / Page,
But whenever I try to create it gives me a RunTime Exception:
java.lang.ClassCastException
at com.sap.caf.eu.gp.ui.co.portal.dt.VBrowse.appendChildren(VBrowse.java:523)
Please suggest some way out,
Thanks in advance,
Deepak

Hi,
How many actions are there in your process?. Is it having only one action that is Web service?.
I think, The process should at least contain one UI action.
If your process is having multiple actions, there may problem with other actions. Test the web service action seperately to confirm this.
Thanks

Info Callable Object of type SAP R/3?

Hi Friends,
I have designed a Business Process using CAF GP, in which, in one of the actions I have inserted an Info Callable Object of type SAP Transaction, though the callable object is working fine with the process,
I can see callable object in a limited area only,
 I am not able to maximize it, neither I can any scroll bars to scroll up and down,
so that I can see full R/3 window within the GP window,
Can anybody help me doing that?
Thanks
Deepak

Thanks David,

Date type attribute in web dynpro callable object

Hi all,
I am creating a callable object with date type attribute as input parameter in a web dynpro callable object.
date type I have used is java.sql.date.
But when I am exposing that callable object in GP its giving an error:
Technical Exception:
Web dynpro Component cannot be created.
And when i am changing date type as java.util.date then I am not able to asssign that date attribute in my view layout.
Can anyone plese help me.

Hi Ritu ,
u have to convert the util date to sql date in the execute method .
do it as showm below in Execute method in the component Controller :
let the Attribute be planEndDate in the Context:
public void execute( com.sap.caf.eu.gp.co.api.IGPExecutionContext executionContext ) {
java.util.Date planEndDate = null;
planEndDate = (java.util.Date) inputStructure.getAttributeAsDate(IContextElement.PLAN_ENDDATE);
java.sql.Date sqlDate = new java.sql.Date(planEndDate.getTime());
wdContext.currentContextElement().setPlanEnddate(sqlDate);
Thanks and Regards

Unable to create callable object of type Webdynpro (GP Interface)

I am getting the following error message when i try to create a callable object of type webdynpro in GP. It was working fine, but when i added component reuse it start giving me the following error:
"Cannot read callable object description from component: <null>"
I also have the library "caf/eu/gp/api" in my project, so i know that is not the problem.
So basically, my project was working fine until i added component resue that it is not letting me create a callable object in GP.
Any help will be appreciated.
Thanks

That problem is now solved, i dont know how but i took out and putted back my component reuse and it worked. But now components that are deployed to the server and are functioning properly, stop working after the server is rebooted. Simply redeploying the component does not make it work again.
A note: One way that we've been able to "work around" this has been to modify the components in some way, rebuild, redeploy. Exactly what modifications that make it function again, is unknown.
Any help on tha issue will be appreciated.
Thanks

I am no able to see the callable object of type
Input under Data forms,
I do have only other 3 types:
1) Data Input Form
2) Data Display Form
3) Data Display and Acknowledgement
and fourth one Input is Missing
Can you please tell me how can I get that,
Thanks,
Deepak

Hi Deepak,
Callable Object of Type "Data Forms -> Input" has been removed. You can view all of the available callable object types by selecting the GP Administration Workset -> Manage Permissions -> Callable Objects. Please see <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/ff/1b3a4209a6ae04e10000000a1550b0/frameset.htm">HERE</a> for documentation.

ABAP Table Type in RFC Callable Object in GP

Hi Experts,
I have created a RFC in ABAP that has as one of its export parameters a table type. I am trying to call this RFC in my GP process. So I created the external service callable object as required. However, when I look at the output parameters for the callable object, the table type is not shown as a list (the is list column is not checked for this parameter).
Do you know if ABAP table types is supported/recognized by GP as a list? or is this a limitation?
Any help is welcomed!
Thanks in advance.
Robert

Hi Aneel,
You can try the following:
e.g.
for j = 1 to ActiveCell.SpecialCells(11).Column
oParam4.Rows.Add
if j=1 then oParam4.Value(j, "NAME") = ActiveSheet.Cells(1,j).Value
if j=2 then oParam4.Value(j, "TYPE") = ActiveSheet.Cells(1,j).Value
if j=3 then oParam4.Value(j, "NUMB") = ActiveSheet.Cells(1,j).Value
next j

Callable object of type Input missing

Hi
I am following a tutorial "Using Parallel Dynamic Block and Dynamic User
Assignment". In this, we are required to create a callable object of type "Input". But there is no search type present in the list of callable objects under "Form".
I have tried using "Data Input Form", but where do i specify the output Parameters.
Can anybody suggest any alternative?
Thanks,
Malita

Hi malita
If it is just for the purpose of learning how to use Parallel Dynamic Block, then please follow the following tutorial:-

Can't able to create callable object using UI pattern in CAF

Hello
I made one interface using object Selection UI pattern for one of my entity services. Now i am trying to make a callable object using this and i also have been successfully created it. But when I test this callable object, I got these error messages.
1. Could not load execution container: Cannot access object class loader for deployable object sap.com/cafcoregpuivisibleco~container.
2. Could not load execution container: ComponentUsage(container): Active component must exist when getting interface controller. (Hint: Have you forgotten to create it with createComponent()? Should the lifecycle control of the component usage be "createOnDemand"?
Please tell me the problem

Hi Saurabh,
It seems you found a bug. The problem is that runtime library reference to sap.com/cafruntimeuicouplingapilib library from sap.com/cafcoregpuivisibleco~container dc is misspelled.
So, I don't know whether or not according CSN is already created but I can propose you a solution.
1. Unpack the cafcoregpuivisibleco~container archive from CAFKM0X_0.sca sca.
2. Unpack sap.comcafcoregpuivisiblecocontainer.wda archive.
3. Open the PORTAL-INF\portalapp.xml file and change the following entry of library reference:
<property name="LibrariesReference" value="sap.com/cafruntimeuicopulingapilib" />
to
<property name="LibrariesReference" value="sap.com/cafruntimeuicouplingapilib"/>And pack
it pack it again in correct order(for ex.:
jar.exe -Mcvf sap.comcafcoregpuivisiblecocontainer.wda .
jar.exe -Mcvf sap.comcafcoregpuivisiblecocontainer.sda .
And finally deploy it to your server instance and enjoy.
Best regards,
Aliaksei
