Benefits of PHP in the context of SAP

Could it be that PHP and SAP integration people do not how to approach it. The concerntration and effort is where the true money is...... Java and ABAP.
I think what we all need to start doing is discussing the benefits of using PHP with SAP. Why should people use PHP with SAP when Java has been doing it for years?

Thanks Max!
I agree with what you are saying. Quite often there is a R/3 server sitting in the company with no connection to the Web developers and with PHP you now have an easy cost effect solution for combining the two together without the large overhead and complexity of Java.
However on the same note if you already have the Java infrastructure in place you should really consider the TCO of a change in that infrastructure. For example we use Java in my company as our programming language of choice for Non-SAP applications and ABAP/BSP for the SAP applications. Trying to convince my company to consider PHP would make little sense because of the investment we've already made and most, not all, but most consider PHP to not be a "enterprise" level application development language.

Handling the context when integrating SAP with WBIMB

I need to integrate SAP systems with an integration platform that is based on WebSphere Message Broker 5 (WBIMB). Now I am looking for a feasible solution to integrate these platforms.
I am concerned about how to handle the context when integrating SAP with WBIMB.
I have read the topic SAP XI and WBI adapters (SAP XI and WBI adapters) in this forum with interest. However, my requirements are slightly different, and my knowledge on development in SAP is limited.
The WBIMB integration platform acts as an Enterprise Service Bus in a SOA. We have a general requirement about guaranteed delivery i.e. once and only once, and therefore the transport protocol is MQ. The HTTP protocol does not satisfy this requirement. Thus we can use Web Services when they are carried as SOAP messages over MQ, but SOAP/HTTP is not acceptable.
The SAP systems can act as service provider as well as service consumer. The WBIMB act as an intermediary, which routes service requests to the proper provider and service responses back to the consumer.
When acting as a service consumer, the SAP system shall specify the context such that WBIMB is able to route the service request to the service provider. Routing is based on the context, which is specified as a property in the MQRFH2 usr folder. Thus the MQ message containing the service request from the SAP system shall specify this usr property, and the value will depend on the requested service. In JMS, the value can be set by calling the TextMessage.setStringProperty method e.g. as TextMessage.setStringProperty(MyContext, XYZ).
When acting as a service provider, the SAP system shall pass the context from the request back in the response message to WBIMB. Actually, I want to pass the complete usr folder from request to response, because it contains more information than just the context property.
I need answers to the questions:
1. How can I set the context from SAP when it acts as service consumer?
2. How can I get SAP to pass the context (MQRFH2 usr folder) from request to response when it acts as service provider?
3. I have looked at the SAP XI JMS Adapter. It looks as I can set additional JMS parameters. But the property value will depend on which service to call. Do I need to setup a JMS Adapter per service or can I set the value dynamically?
4. Can the SAP XI JMS Adapter pass the context from request to response?
5. Are there better alternatives than using the SAP XI JMS Adapter?
Many thanks for any help you can give me in advance.

Hi Daniel,
Thanks for your answer. I expected it would turn out this way
So the good news is that when SAP is acting as service consumer it sounds fairly easy to set up a mapping from XI message to MQ context.
But when SAP acts as service provider it sounds as more customisation is required and I am worried about having to save the state. It will hit performance when the context is not carried as part of the message. In this case I prefer to use a generic solution on WBIMB, where I can handle the context for SAP (as well as other service providers). Then I only depend on the ability to set correlation in the response. But it will still cost performance because WBIMB also has to save the state on temporary MQ queue.
Ideally, the SAP XI/Adapter should be able to pass the context 'out-of-the-box' to better support intermediaries like the WBIMB as ESB. I put this on my wishlist
Anyway, I appreciate that you was able to confirm my observations.

How to check the file size before loading it to the context

Hello,
I have an application to upload a file and write it to the server using the FileUpload UI and IWDResource Interface.
I would like to limit the size of the file the user is uploading to, say, 2MB.
The problem is that the current API doesn't allow me to check the file size before I store it in IWDResource. The API available for IWDResource:
IWDResource resource = ...
InputStream stream = resource.read(false);
size = stream.available();
Is working on the file only AFTER storing it in the context and the server's memory. This way, if a user decides to upload 1GB file for example, he can easily crash the server.
I am already familiar with <a href="https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/00062266-3aa9-2910-d485-f1088c3a4d71">this</a> arcticle but it doesn't answer this question as well, all it does is calculating the file size only after storing it in the context.
Any ideas...?

How to add a new Element to the Context

Hello all.
I created in the wdInit()
ArrayList datas = new ArrayList();
 for (int i = 0; i < 25; i++) {
 MyData data = new MyData();
 data.setMethods();
 datas.add(data);
 wdContext.nodeMyData().bind(datas);
Now, I want by clicking on the Button "Create new Element", forward user to the other View, which elements are connected with the same model -> context, the new element should be added to context, the user should fill the form and click Save-Button.
How can I add a new Element to the Collection I created and choose it as a current element?
If I do: wdContext.nodeMyData().bind(new MyData()) all information will be lost. And I will have only one field.
If I do it like this:
IWDNodeElement dynTabElem=(IWDNodeElement)wdContext.nodeMyData().createElement();
wdContext.nodeMyData().addElement(dynTabElem);
I get an error: com.sap.tc.webdynpro.progmodel.context.ContextException: NodeInfo(DataComp.MyData): value node is created without a reference
Well I can pass to my new View a Collection as a parameter and then
Collection.add(new MyData()) and then bind it. But I find this solution not good.
Is there any possibility to get the existing Collection from the Context without passing it to the view?
Can I just add a new element to the existing collection?
Thanks in advance.

Hallo Monalisa,
I did as you said. But I can't add something to my model class, because it is not collection.
 MyData data = wdContext.currentBelegElement().modelObject();
 data.add() ???? - don't work
 wdContext.nodeMyData().invalidate();

How to bind a UI element to the context

Hi Experts,
 I have a problem binding UI element to the context. In my code i have to create TabStrips dynamically and under this tabstrip number of UI elements would be there. For this i have a code like this..
IWDTransparentContainer theActionContainer =(IWDTransparentContainer)view.getElement("RootUIElementContainer");
 IWDTabStrip ts = (IWDTabStrip) view.createElement(IWDTabStrip.class,"TabStrip");
 IWDTab tab1 = (IWDTab) view.createElement(IWDTab.class,"Tab1");
 IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
 IWDCaption header1 = (IWDCaption) view.createElement(IWDCaption.class,"Header1");
 header1.setText("Tab1");
 tab1.setContent(in);
 ts.addTab(tab1);
 IWDTab tab2 = (IWDTab) view.createElement(IWDTab.class,"Tab2");
 IWDInputField in2 = (IWDInputField) view.createElement(IWDInputField.class,"in2");
 IWDCaption header2 = (IWDCaption) view.createElement(IWDCaption.class,"Header2");
 header2.setText("Tab2");
 tab2.setHeader(header2);
 ts.addTab(tab2);
 theActionContainer.addChild(ts);
when i run this code it is giving following exceptions..

From these exceptions what i understood is, i need to bind these UI elements to context.
 Can any body tell me how to bind a UI element to the context if I understood the exceptions correct..
Thanks in Advance,

HI,
lets say Ctx is your context attribute,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getAttribute("Ctx");
then , as per your code,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
in.bindValue(attrInfo);
if your contex attribute is child of some other node then do like this,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getChildNode("SalesOrder",0)getAttribute("Ctx");
//this is when Ctx is child of node SalesOrder, and we are taking Ctx from its 0th element
then ,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
in.bindValue(attrInfo);
include this in your code ,
let me know if you face any problem

Dynamic table data isn't transfered to the context, with webdynpro for java

Hi,
I'm using LifeCycle designer 7.1 and Adobe reader 7.0.5.
I'm trying to make a dynamic table in a PDF form, that will be related to a table in the context.
I've designed the context like it says here: Dynamic Table - same data repeating in all rows
I made a dynamic table and related the cells on the row to the context, by dragging the variables from the DataView into them.
The table is related to TableList, the row to TableWrapper[], and the cells are related like this: TableData[].ItemName
And there's a button which adds a row to the table.
And for some reason, that's not working; When hitting the Submit to SAP button, it doesn't appear as though the data was transferred to the WebDynpro context.
Can anyone help me with it please..?
By the way - I tried using the SAP standard subform controls, the 'Insert Remove Move' control.
When trying it through the PDF preview, it doesn't work - whatever I click displays an error message, and when it runs from the browser - It automatically searches for an update for Adove Reader (I use 7.0.5).
Is it supposed to work only with version 8 of the Adobe Reader?

Well, I reinstalled ACF, and now the Submit button works, and the Insert Remove Move buttons work as well.
But the table context still doesn't work.
I had put some values in the context, in DoInit, and they appeared in the table in the form, but when I changed them in the form it didn't affect the context at all.
There's a simple attribute value related to a text field, which IS affected when changed in the form, and the Submit button is clicked. Only the table doesn't work.
How can I make it work?
Thanks,
Udi Dekel

Need help in learning XML in the context of ABAP

Experts,
I am wondering if you can help me.
I know abap (up to SAP 4.6c versions) but I know nothing about XML ( I am literally zero on XML). I want to learn XML in the contexts of ABAP programs in SAP Netweaver versions. I tied to google XML tutorials but information is overwhelmingly too much. I do not intend to become an XML expert but want to be able to learn XML only to the level where where I can use them in ABAP programs.
Can you guide me if there is some step by step material / documents/ tutorial on internet which is not too much?
Thanks

Structure of the context for declaring internal table

Hi,
Can we use the structure of the context for declaring the internal ?
-Sid

Hi Sid,
You can use the above element_ & elements_ notation to define workarea & internal table similar to your context. But the disadvantage of this approach as how pointed out by Thomas in 1 of his earlier threads is that this coding would work fine only for that particular view. If you copy the same code from your view input_view and try to use it in another view say VIEW1 then it wouldn't work as the interface name would have changed from if_input_view to if_view1. So its suggested to use the below approach:
DATA: lt_main TYPE wd_this->elements_node_vbak, " Internal table
wa_main TYPE wd_this->element_node_vbak. " Work area
Try go through this excellent [article|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/60730016-dbba-2a10-8f96-9754a865b814]. It would help you understand what all you need to know about working with the context & its attributes.

Uday

Hi Axel,
I've just found your question by accident and would like to know whether you have already implemented 10gRAC in SAP environment?

Please, tell how can i solve this problem ?

Hi Konstantin,
it has nothing to do with the number of system threads. You are obviously executing several function modules statefully in multiple threads within the same session context. Stateful requests can only be executed in an ordered manner in case they should belong together. You are using ARFC2, which is part of the WebDynpro runtime. In case you are sure that the calls are independent from each other, it might be a good idea to adjust the scope type of some of your bindings. Then the requests will be executed with different scopes depending on your configuration and you can execute them concurrently
Best regards,
Markus

Add custom command in the context KM menu

Hello All,
Wanna know if its possible to add custom command in the KM context menu?
If yes, please guide as to how can I do this....
Example: Print option in the context menu
Awaiting Reply.
Thanks & Warm Regards,
Ritu

Hi Ritu,
   Yes, you can do that.
   First of all, you should identify the layout set that you are using. If you do not know it you can enable debugging setting option.
   Then, you must know where you need to appear this command. I mean, in a folder, link or document.
   If you are using a standard layout you should not modify it, you must duplicate it (you ca use advance copy).
The command must be added in a group command, you can use an exist command or create a new one. (System Administration-System Configuration-KM-CM-User Interface-Command Groups). Before that you can create your command.
These groups are referenced from collection and resource renderer. A layout set is a set of collection and resource rendeders.
You should read this link.
http://help.sap.com/saphelp_nw2004s/helpdata/en/98/dd48a9b4a197489a54187c99372bce/frameset.htm
Once you added your comamnd a group and assign this group in your collection or resource renderer. You have to assign this layout to your km navigation iview or directly the folder.
Don't forget to enable presentation service in your repository in order to change the layout.
Patricio.

Sharing the Metadata Repository (SAP Java Connector)

Is it possible to share the metadata repository across multiple client processes in the context of the SAP Java Connector? If so, can someone point me to the technique that I have to implement?
Each client process creates its own JCO.Pool (with a unique key) and obtains a repository by invoking JCO.createRepository(...).
Thanks in advance.

Hi jim,
You will probably find the answer in this article :
