Linking of Service to Callable object for execution

Hi,
I've created a process and an action . In action I've inserted few fields which are mapped to an Interactive adobe form.
Once the user submits the Adobe interactive form I have to process the values and update the R/3 database with a service.
Where can I find the list of available services and how & where should I map the input field to that of an existing service?
Regards

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:

Re: Callable object for display

Hi all,
I would like to know how a can create a web dynpro component with GP interface so that i can set config (display mode or exceution mode) of CO in GP.
after deploy the WDPro component , I had tried to create a CO in GP, but i can not set the configuration properties of the CO.(It is default to callable object for execution)
And in the help of the NW Studio, it said some coding is needed.
So could anyone give me some guide in doing so.
Thanks In Advance
David

Thx for your reply first.
However I had already have a look on this tutorial, no hints about how to work on CO that is for display.
For example, in that tutorial when creating CO, there is a step for setting configuration initially, but after defining the input or output, that step disappear and the CO is automatically set as "callable object for execution"
In GP, there is an example Time Off Process, in which at each action we can see a CO for execution and CO for display.
So I would like to know how to implement it.

Exposing Web Services as Callable Objects

Hello!
I have SAP NetWeaver 04s SP7. How can I expose Web Services as Callable Objects?
According to "Exposing Web Services as Callable Objects" (http://help.sap.com/saphelp_nw2004s/helpdata/en/44/4758351fcb1193e10000000a155369/frameset.htm), I should start with choosing type of CO "Service -> Web Service".
Actually, I haven't this entry in CO type list!
According to integrate Web Services with GP, this type appeared in SP8. What are the alternatives in SP7?
"Background execution" and "External service" seem to be the best candidates...
What is the best solution?
Thanx in advance!

Hello, Jan!
I have SAP NWDS 7.0.07, and I cannot find there an option to create a CAF project. I can create Web service, EJB, Web DynPro, and something else - but not a CAF project. In documentation I did not find the connection points between NWDS and External Services, except some plug-ins.
Maybe I've misunderstood you, sorry - I'm a newbie in SAP
Actually, I've made a simple EJB, created a Web service from it, and deployed the WS to portal. Maybe, EJB instead of Web service can be somehow used in CAF?
I've tried to create a CO of type Composite Application Service, but there was necessary to configure endpoint aliases. I've read the manual "Configuring Endpoint Aliases", but didn't succeed to make one for EJB remote call... I've defined the name, URL (http://<host_of_portal>:<portal_port>), user and pwd - but I've got an exception when tried to use the created alias:
com.sap.caf.core.gp.servicelocator.exception.MetaModelBrowserException: Exception while trying to get InitialContext. at com.sap.caf.core.gp.servicelocator.CAFMetaModelBrowser.getAllApplications(CAFMetaModelBrowser.java:77) at com.sap.caf.core.gp.ui.backgroundco.admin.VSelect.browseCAFCore(VSelect.java:305) at com.sap.caf.core.gp.ui.backgroundco.admin.VSelect.onActionSelectEptAlias(VSelect.java:750) at com.sap.caf.core.gp.ui.backgroundco.admin.wdp.InternalVSelect.wdInvokeEventHandler(InternalVSelect.java:287) at com.sap.tc.webdynpro.progmodel.generation.DelegatingView.invokeEventHandler(DelegatingView.java:87) at com.sap.tc.webdynpro.progmodel.controller.Action.fire(Action.java:67) at
Maybe, the easiest way is to upgrade the versions of SAP and NWDS?
Are there some manuals that could provide me some help about:
1) creating CAS from the deployed Web service (from its creation in NWDS till its use in CAF, step-by-step)
2) binding Web Dynpro apps and Web services, using CAF and GP.
Or maybe I should attend SAP courses?
I have SAP NetWeaver 04s SP7 and NWDS ver. 7.0.07.
Sorry for the messy post, I did my best

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

Implementation callable object for background execution

Hi experts,
I am Using NWDS 7.0
while i am trying to create background execution callable object , i didnt find the DC :caf/eu/gp/api.
so i followed the pdf "How to Get NW04s SP7 Guided Procedure APIs for Local Development" and added the required DC's.
The problem is that while i am selecting the dc "caf/eu/gp/api" the following message is displaying
"illegal dependency: Acess list does not allow use of sap.com/caf/eu/gp/api for sap.com/bckg_co(MyComponents
Is there any other way to add DC's ?
pls help me out
Thanks in advance
kiran

Hi Kiran,
1. go to development Infrastructure --> select ur Software component --> in the component properties Tab > select dependencies Tab->click on Add Button.
2. in the pop up window , select the Software component (Gp - Core) which has the caf/eu/gp/api component and give the dependency details and click Finish.
3. Ensure that Unrestricted acesss is granted for this component. this u can check, by selecting caf/eu/gp/api and select permissions tab in component properties.
hope it helps,
Thanks and Regards

Info Callable Object for reduced circle

Hi,
Is it possible to make an <info callabale object> accessible only for a reduced user circle.
I found no a way to implement this

Hi,
You can assign dedicated permissions to GP Callable Objects (CO):

Background callable object for BAPI

Hi Everyone,
I have a requirement wherein a BAPI call should be an intermediate action in a GP process.
I need to fill in some fields in an interactive form which is in the preceding action, the fields on being mapped to bapi input will be passed on to this bapi, after the bapi call a notification (third action) will be sent out to all process contributors . All these three actions are done by the same role. I am able to use BAPI external service CO successfully when its the beginner action in any process. But on being an intermediate action it doesnt execute. I am new to GP and I dont know of any alternative methods.
Experts plz guide.
Thanks,
Lisha

Hi Lisha,
please refer to the following link:

You should focus on the topic "Creating and configuring forms" in special:
"Building a Form Context"
"Dynamic Forms".
Please be aware that in NetWeaver 7.0 (2004s up to SP13) the CO Composite Form were called CO Interactive Form. But basically the functionality "Building a form Context" remained the same, although named a bit different.
As I don't know which SPS you are working with and whether it is NetWeaver 7.0 or CE, please come back to me if you need further explanations.
Hope this will help to proceed your work.
Kind regards

Cannot load callable object container: null

My application is webdynprojava application with GP process.
One of my scenaio was to create a popup window with ok button after completed the action.
First I tried from code where i was written to completd the action
but it did not work because the popcode i was writing before the complete method but it always talking after
completeso results i was getting error .
Then for the same action i created one callable object for display.
That time my application was working after some time I again check
then its showing    Cannot load callable object container: <null>
this error for the callable object which I created for popup window with ok button.
(once RM will approve ,popup window will come with ok button ).

Last time I checked contexts and lookups could return null values. And your code is not checking for a null value return.

Web Services as Background Callable Objects?

Hi everybody,
is it possible to use an Web Service as an Background Callable Object? And if it is possible, how can I do it?
For your background: If the Web Service throws an Exception, I want to handle it. My goal: The next step after finalizing the exception handler action will be the
action (WebService) that reported the exception. Or is there any other possibility?
Thanks,
Stefan

Hi Stefan,
For repeating the WS Call after the exception handler, you can use the "repeat" strategy. When defining the exception handler, you can choose between "continue" and "repeat".
Check this page : <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/44/10a066e3650d19e10000000a114a6b/frameset.htm">Exception Handling in GP</a>
For using Web Service as Callable Object, check this out! <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/44/4758351fcb1193e10000000a155369/frameset.htm">WS in GP</a>
When specifying repeat, the action will be started again. If continue, the next action will be processed.
Hope this helps,
Best regards,
David
