No CALL METHOD syntax used in Dynpro programming

Hi Gurus,
I have just starded with Web Dynpro ABAP. I found that while writing code we don't use CALL METHOD .
i.eTABLE_NODE = WD_CONTEXT->GET_CHILD_NODE('MY_TABLE_NODE').
How can we directly call a method using interface variable e.g WD_CONTEXT without syntax CALL METHOD?
Can anyone explain?
I am not much familiar with OOPs.
Thanks in advance.

Hi Anzy,
Can u correct this program to let me understand this concept. ( An example ABAP OOPs program)

How can we call methods of one web dynpro component in another one

Hello Team,
How do I call one Web Dynpro component methods in another Web Dynpro component.
How do we use public parts.
thanks

Hi,
You want to use Comp2's getData() method in Comp1
If both the WebDynpro components are in the same DC:
1. Create a wrapper method (with the same signature) in the Comp2's Interface controller. And invoke the Component contorller's getData() method in this method using the below code.
wdThis.wdGetComp2Controller.getData()
2. Now Go to the Comp1 and right click on UsedWebDynproComps and add this Comp2 as a UsedWebDypro component.
3. Now go to the Component Controller of Comp1 and in properties tab add the usage declaration of Interface controller of Comp2.
4. Now using this below code you can access the method of InterfaceController of Comp2.
wdThis.wdGetComp2Interface().getData();
If both the WebDynpro components are in different DCs:
1. Right click on Comp2 and select Add to public part on Comp2 in DC2.
2. Now Add this public part in DC1 UsedDCs.
Now repeat the above stpes 1...to..4. of "If both the WebDynpro components are in the same DC" same.

How to call method excel subtotal in ABAP program

I'm trying to call excel method subtotal, but i get an error (sy-subrc <> 0). How to correctly call this method? One of the parameters is an array. I've tried to use an internal table as the array, but ABAP syntax checker shows error.

Hi Vytautas,
The best way is to start recording a Macro(Tools->Macro->Record New Macro), and then do the operations (like entering data into cells, summing up, calculations,etc...)
once you are done, display the macro and you will find all the needful information regarding what metohds are to be called and how...

Cross-component: Call method of using component from within used component?

Hi,
I began diving into cross-component programming.
Meanwhile after having digged into some scenarios some questions came up to my mind that I am not able to answer myself. I would appreciate your help here!
Say we have to components. Comp A uses Comp B (hence, B is a component usage in A)
1) How to make them communicate not on a data level (via context binding) but on a process level, thus...
a) can I call A's method from within B? How is the approach on a general level? - as B can be used from totally different components (like A, A1, A2 ...)
b) perhaps the only way to do this is by firing events? If so, how can I react in A when an event in B (marked as interface event) gets fired? As it seems they do not get registered within A directly...
I guess the question seems to be a bit tricky. Nevertheless, I think there will be plenty of you out there who used to asked them the same questions before and came up with an approach. Would be nice to hear from you.
Best wishes,
Marc @sap1

Hi,
thanks for your reply!
Indeed, I think the nature of WDA would be just to somehow map the context from the used component to the other back and forth.
Nevertheless, what if I would like to invoke a method of the using component from inside the used component.
One sample for this requirement could be e.g.:
Component B offers a tree item and a send/verify button.
Component A uses B and has some restraints regarding what the selection should look like.
The user taps the button in B (at runtime in the view container of A), the context gets updated in A and B and in Component A the verifyWithOwnConstraints() method gets called (through B).
Thanks again,
Marc

How to use CALL METHOD

Hi Xperts,
how To CAll Methods In SE38.
isit just like calling function module .
Can any one guide me through the process with small example and TCODE.
Thank You in Advance.

Hi,
to call a method u should use syntax from SAP help...
Static Method Call
1. [CALL METHOD] meth_identifier( parameter_list ).
   CALL METHOD meth_identifier parameter_list.
Short Forms
2. [CALL METHOD] { meth_identifier( )
                | meth_identifier( a )
                | meth_identifier( p1 = a1 p2 = a2 ... ) }.
Dynamic Method Call
3. CALL METHOD meth_identifier { parameter_list
                              | parameter_tables }.
Effect
Call of a method in ABAP Objects. There is a difference between a static method call, in which the method ID must be fully known in the program, and a dynamic method call, in which the method ID is determined entirely or in parts at runtime. The static method call can be executed in different forms. In one form, the parameters are passed in a parenthetical expression, in the other without a parenthetical expression. For the parenthetical expression, short forms are allowed. With the dynamic method call, you are not allowed to specify the parameters in parentheses and you must use the statement CALL METHOD.
When you call an instance method using a reference variable and the static type of the reference variable is a superclass of the dynamic type, then you can use the dynamic method call to call all visible methods of the dynamic type, whereas with the static method call, you can call only the visible methods of the static type.
Note
Functional methods cannot only be called with CALL METHOD, but also at operand positions.

Error on Calling Methods Using an Object of a Class

I keep getting the error cannot resolve variable addStud . I can't figure out why. I've created objects of classes before this way, then called methods within that class like this and it worked fine. I can't discern any difference between the syntax of the program that worked successfully and this one. I commented the parts where the error is when I tried to send a variable to a method in the class Recieve of which addStud is an object of. If you can see something that I can't I'd appreciate it. I've checked the obvious things like making sure the class name and method name is spelled the same way in both my frame and the class file.

How to use the catalog in our own Web Dynpro program?

Hi Expert,
How to access MDM catalog and bring the product data back to a our own Web Dynpro program?

Hi Masa,
The Catalog Search UI of SRM that is referred to as UI as aforementioned is a page which is capable of the selection of catalog items is linked from the shopping cart creation.
Our biz requirement content two scenarioes to processing the purchase requirement.
A. Create shopping cart via the catalog (PR) --> SRM PO Process --> SUS(PO and Invoice)
This is the standard SRM purchase scenario and we have already implemented that.
B. Create a requirement document via the catalog (This document is same with the SC but very simple, and we create this function by the own web dynpro program) --> transfer the requirement document to other purchasing system(none SAP) in our intranet.
So the key problems we faced are below:
1. How to connect to the catalog search UI from our own web dynpro program.
( If we connect the catalog via the MDM ABAP API, that will make the catalog serach UI could not be used;
Also it has been failed to simulate the function of SC's connection to the catalog;
So we decide to link the catalog serach UI via the URL, the linkage is "http://<J2EEserver:J2EEport>/SRM-MDM/SRM_MDM?sap-locale=EN&HOOK_URL=&mask=&namedSearch=General&username=&password=&catalog=<Repository Name>&server=&datalanguage=EN". )
2. How to transfer the catalog item data to our own web dynpro program.
If we link the catalog search UI by URL, we can not find any good method to transfer the catalog item data to our own program.

Syntax for how to call method of one comp in other comp     wd java.

Let us assume,
there is method1 in view1 comp1.
tell me syntax for calling method 1 in view2 comp2
thanks in advance.
Edited by: madhu1011 on Nov 9, 2011 11:31 AM

Hi Madhu,
This is the situation:
comp1-> method 1 , view1
comp2-> view2
You need to access method1 in view2 of comp2.
For that, do the following steps:
1.) First create a method (for eg: method1) in comp1 (under implementation of view1).
        eg: public void method1(){
                <......some logic...>
2.)Save the meta data.
3.) In comp2, you will find an option called used components. In that right click and add the component comp2. (Carefully select comp1 itslef).
4.)Save the meta data.
5.) Then go to view2 of comp2 and take implementaion part and right the following logic in wddoinit() (or any other standard or custom method).
wdThis.wdGetComp2Interface().getMethod("method1");
By this way, we can access the method1 of comp1 in comp2.

Jithin

Why do we use cl_gui_cfw= flush method in Object Oriented ALV programming

Dear Friends,
Please solve my query regarding control framework. Why do we use cl_gui_cfw=>flush method in Object Oriented ALV programming. I studied and found that this method transfers automation queue to Front end. But I could not find any further update on this.
Thanks & Regards
Amit Sharma

Generally this is to restrict the traffic b/w frontend and backend. This means that every operation in Control Framework should be first buffered in the backend and synchronized with the frontend at certain points (one of this point is calling synchronization method cl_gui_cfw=>flush ). This explicit order of synchronization is due to RFC call needed for every communication b/w front/back end. So to avoid to many RFC calls we do it only at certain time.
Please refer [Automation Queue|http://help.sap.com/saphelp_wp/helpdata/en/9b/d080ba9fc111d2bd68080009b4534c/frameset.htm]. I think it explains the concept quite well.

Call a external vendor catalog - OCI In ECC using web dynpro

Hello Everyone,
We have a requirement to call a OCI External Catalog in ME51n Transaction in ECC, that is working fine.
Now we need to create a Web dynpro ABAP Application which performs the Task of ME51n Transaction along with OCI Integration.
So far i have create a small Web dynpro ABAP application to check does OCI Catalog can be integrated in ECC using web dynpro ABAP.
My Screen Consit of a single Button UI, on click of the button i am calling the External Catalog, from the catalog i select all the materials and click on submit finally we need to bring all the selected materials to get displayed ina table.
Half of the Development is done i.e i am able to call the catalog but not able to receive the selected materials.
following are the details-
1. I check in SRM first how the Ctalogs are been called, i found 2 Services responsible for the same in SICF transaction -
Inbound HLDR and Outbound HLDR which uses handler class as SAPSRM_CL_CH_WD_INBOUND_HDLR and SAPSRM_CL_CH_WD_OUTBOUND_HDL, so i copied the same classes into ECC and created the same SICF Service.
Contn. in next post

2.In my Web Dynpro ABAP application i have a Inbound plug in my window in the handler method of the inbound plug i fill a table lt_parameters of TYPE tihttpnvp, it has 2 columns name and value
In this table i fill following entries-
Name-CATALOG_URL
Value-https://XXXXXXXX.com/invoke/BVProcess.SAPOCI/processCatalogRequest
Name-USERNAME
Value-XXXXXXXX
Name-PASSWORD
Value-XXXXXXXX
NAME = 'HOOK_URL'.
VALUE = 'http:/XXXXX.hostederp.local:8000/sap/ZOTC_CAT/Zinbound_hdlr'."?TARGET_URL= {Appdress of the WDA Apllication}
NAME = 'OCI_VERSION'.
VALUE = '4.0'.
NAME = 'OPI_VERSION'.
VALUE = '1.0'.
NAME = 'returntarget'.
VALUE = _top
also in this inbound plug handler method i fill a lv_url variable of type string with-
lv_url = 'http://XXXXXX.hostederp.local:8000/sap/ZOTC_CAT/Zoutbound_hdlr?sap-client=100&sap-language=E'.
3. finally from the handler method of the inbound plug i call a Suspend plug p[assing the above two variables i.e
lt_parameters and lv_url.
wd_this->fire_zw_suspend_plg( url = lv_url i_parameter_tab = lt_parameters ).
4. Using above i cam able to call the catalog and select the materials.
5. Now if i Finally clcik on submit on the catalog it should return the materials to the WDA Application.
For WDA Application to accept the Materials i have created a resume plug in which i am using -
wdr_task=>server->request->get_form_fields( CHANGING fields = lt_fields ). to get all the selected materials into lt_fields.
6. But unfortunately i am unable to receive the selected materials in lt_fields.
I think i am missing something in Hook URL or some other parameter.
Please help, ur comments and suggestions are welcome.
Regards,
Akash Rana

Call transaction VA01 or VA03 and skip first screen using Web dynpro

Hello Experts,
I am calling the standard transactions using Web dynpro via ITS.
I am able to reach to the initial screen of the standard transactions say VA03 and populate the sales order number through Web dynpro.
My requirement is to skip the first screen of the transaction.
I tried passing the screen number in the URL link but still it is showing the initial screen.
Please suggest me solution for this.
Thanks and Regards,
Rahul Sinha
