Display Result in FPM_LIST_UIBB_ATS

[Former Member]

Hello FPM Expert,

I have one small doubt related to Webdynpro and FPM.

Doubt:- i have two Independent Components. Search(Webdynpro Component) and Result list(FPM_LIST_UIBB_ATS). Both are Independent to each other.

and i cogigured both component  in FPM_OVP_COMPONENT.

based upon the search crieteria in Search componet , coresponding result should display in Result list(FPM_LIST_UIBB_ATS).

           But while i give  some material number and click on Search button (This stuff is in webdynpro componet ) the result should display in   FPM_LIST_UIBB_ATS component. i am trying to use IF_FPM_APP_CONTROLLER. But i didnt find any proper  way to implement it.

For that any body has  any sample documents or solution ? any body can help me on this?

Thanks in advance!!

Hi Rakesh,

I had the same problem that you described. How to share data between GUIBB's?

Unfortunately SAP doesn't provides a framework for this. The answer from SAP is that you should create a singleton class which stores the data you want to share between the GUIBB's.

Well I think this solution is crap, so I have created my own connection framework for that, but that is a little bit out of scope for now.

The best thing you can do is to create a parameter in the GUIBB and call a class that combines a factory and singleton design pattern with that parameter. the factory/singleton should return a central data instance where you can store your data you want to share with other GUIBB's. This look a lot like the singleton approach, but when you use a parameter and a factory, then u can use you GUIBB with more configurations in the same application or use it in a totally different application. Your GUIBB will be reusable and I think that is the idea of GUIBB's.

You have also Wires, but a Wire provides only access to one other GUIBB so that is not really an option. Wires are mainly created to notify an other GUIBB that an event occurred, for example lead selection changed.

Hello Robin.

Thanks for Your reply.

This information is really helpful for me.

Can you please provide me some documents/information(how to use) for factory and singleton design pattern.

so that i can go through and will try to implement the same in my application.

Thnaks

Rakesh.

Hi Rakesh,

You can find more information about the singleton factory at:

Dear all,

Wiring between components can be done mainly by two type of FPM class.

Transaction Handler class: It is implemented globally for a FPM Application. However, it is not mandatory to specify. So, you can make an application without using any transaction handler.

Use interface IF_FPM_WIRE_MODEL_TRANSACTION

Connector Class:  It is main and mandatory part for implementing wire model. Here you can specify the Namespace and this namespace plays big role for passing data.

Namespace: The definition interface possesses a static attribute, “SV_NAMESPACE”, which should be filled with the namespace (ex. ‘FPM_DEMO’ or ‘BOL’ or user specific such as XYZ_NS) in the class constructor of a connector implementation.

Wire for Free UIBBs

            Wire model is implemented on Web Dynpro component by implementing “IF_FPM_UIBB_MODEL” Web Dynpro interface. It contains only one method “GET_MODEL_API” which is used to set “FPM Feeder Model” for Free GUIBBs. It contains only one parameter “RO_FEEDER_MODEL”. So, we have to create a FPM Feeder Model class and assign to that parameter.

            FPM Feeder Model Class – Interface “IF_FPM_FEEDER_MODEL” is implemented for creating Feeder Model Class.

                        Assistance class can also be used as Feeder Model Class and reference “WD_ASSIT” can used as Feeder model instance.

Ex:       METHOD get_model_api .
ro_feeder_model = wd_assist.
ENDMETHOD.

Wire for GUIBBs: Nothing special we need to do that.  Interface “IF_FPM_FEEDER_MODEL” is also implemented on feeder class for getting port support. We need to set port manually using structure “IF_FPM_FEEDER_MODEL=>CS_PORT_TYPE”. It contains three constants “COLLECTION”, “SELECTION” and “LEAD_SELECTION”. It should be properly configured.

In addition of this, create collection handler class that will be passed between components for retrieving and fetching data.

Dear All,

    If you want to implement Wire model to pass data between components, I will give a proper example for doing this.

Hi Manishekhar,

thanks for your reply.

If  through Wire model , this can be done  . Please give an example.i will try to implement .

Thanks

Dear Rakesh,

Sharing Data between UIBBs from different Components

When the UIBBs of an application are implemented in several components, there is

often the need to share data between these components. Technically, there are several

approaches which you can take to achieve this. This is described in the following

For this purpose, the FPM offers Shared Data components.

This is an optional FPM feature which meets most applications’ demands. However,

if needed, it can be replaced by other technical alternatives as described in “Other

Options for Sharing Data”.

Using a Shared Data Component

A shared data component is a Web Dynpro component which implements the

IF_FPM_SHARED_DATA interface. This interface contains no methods or attributes but

serves as a marker interface only. Each component (e.g. UIBB,

FPM_OIF|GAF_CONF_EXIT component) which wants to use a shared data

component needs to declare a usage to the shared data component. For this, the

technical type of the usage does not need to refer to IF_FPM_SHARED_DATA (this

would mean that it would not have accessible methods/attributes) but link to the

actual component itself. The lifecycle handling is now handled completely by the

FPM. Whenever a component is instantiated by the FPM (e.g. a UIBB which is

configured for a given screen), the FPM analyzes all usages of that component. If it

detects a usage pointing to a component which implements the IF_FPM_SHARED_DATA

interface, a singleton of this shared data component is automatically attached to the

usage.

As a result, an application must proceed as follows to share data using the shared data

interface:

Create a component which implements the IF_FPM_SHARED_DATA interface.

This component contains methods to retrieve data from the business logic and

exposes the extracted UI data via its Web Dynpro context or interface

methods.

Each component accessing this shared data defines a usage of the shared data

component. This usage is automatically instantiated by the FPM.

The consuming component can now communicate with the shared data

component via Web Dynpro context mapping, attribute access or method calls.

Other Options for sharing Data

There are other options to share data between Web Dynpro components besides the

FPM shared data concept. There are occasions when it is best not to use a Shared Data

component, as detailed below:

There is already an application-specific API available which serves as a ‘data

container’ and can be accessed by several components.

The data needs to be shared not only between Web Dynpro components but

also between other entities, such as ABAP OO classes, function groups, etc.

The amount of data to be shared is so large that putting it into a Web Dynpro

context would result in performance and memory consumption issues.

In these cases, the application can consider using techniques such as the following:

An ABAP OO class which is accessible as a singleton, so that all consumers

share the same instance.

A function group with appropriate function modules.
