Is it possible to create Adobe Interactive form in ECC 5.0 IDES using WDA?

Hi every body,
I am trying to create an adobe interactive form in ECC 5.0 IDES using Web Dynpro for ABAP. But I am facing some configuration problems. My doubt here is -> "Is it possible to create abobe interactive forms in ECC 5.0 IDES using Web Dynpro for ABAP ?"
Please help me out.
thanks in advance,
best regards,
naveen.

Hi Naveen,
ECC 5.0 is NW04 - not NW04s so you don't have WDA at all as you should be able to see from e.g. it not appearing in the list of possible programming objects in transaction SE80.
You'd need ECC 6.0.
Double-check your SAP_BASIS release in menu System > Status > Component Information. If it says 6.40 then that's no good... you need to be on 7.00.
You can still use Java WebDynpro with ECC 5.0 of course.

Can we use bdc in WDA?

hi,
      can we use bdc in WDA? if yes please tell me how to do?

Dear Murthy Ganti ,
yes it is possible by creating the Functional module for your BDC recording . i.e you will get the code generated by the BDC recording . create a FM using the Code .
for example the below code is your recoding code
Assign your import parameters to your code
wa_iq02-MATNR      = MATNR.
wa_iq02-SERNR      = SERNR.
wa_iq02-GWLDT_O    = GWLDT_O.
append wa_iq02 to itab_iq02.
clear wa_iq02.
LOOP AT itab_iq02 INTO wa_iq02.
PERFORM bdc_dynpro      USING 'SAPMIEQ0' '1000'.
    PERFORM bdc_field       USING 'BDC_CURSOR'
                                  'RISA0-MATNR'.
    PERFORM bdc_field       USING 'BDC_OKCODE'
                                  '/00'.
    PERFORM bdc_field       USING 'RISA0-MATNR'
                                  wa_iq02-matnr.                      " IMPORT parameters
    PERFORM bdc_field       USING 'RISA0-SERNR'
                                  wa_iq02-sernr.                        "IMPORT parameters
CALL TRANSACTION 'IQ02' USING bdcdata MODE 'N' UPDATE 'S' MESSAGES INTO IT_MSG.
IF sy-subrc EQ 0 .
*      CONCATENATE 'Material No ' matnr sernr INTO text.
      return_message-MESSAGE = 'Address was updated '.
     else .
       return_message-MESSAGE = 'Address Was Not Changed '.
    ENDIF .
ENDLOOP .
and check your FM is working fine . and consume it in WDA through call function or service call
revert back if any doubt

WDA-Flash Data transfer Frequency

Hi
I have some WDA program with Flash Island inside. I share some objects (tables) from WDA to Flash, and Flash make graphics.
So i have in WDA conext the requiered nodes (for each table) wich i fill in WDA and share it to Flash.
My doubt is about Data transfer frequency between WDA and Flash:
If i change a node content, ie. i fill the node again with the new table content, this node is shared automatically with Flash, thats good when i change all records from that node (table).
1. If i have a NODE_A with 100 records , if i only change the content for one specific record , does
all the node content (all 100 records) are transfered to Flash ?   I guess yes.
2. But if i have NODE_A (100 records) and i have other NODE_B (150 records) and i change the NODE_A content ; does NODE_B content are transfered also to Flash even this node has not changes ?
3. Suppose i have other Node (not table) with attribute to enter Date wich is shared to Flash , if i change that Date ,   does the nodes NODE_A and NODE_B are also transfered to Flash even these have not changes ?
4. If i do not make any change to nodes shared with Flash , when i make any event (press match code) or change some node or attribute wich are not shared to Flash   ; does nodes NODE_A and NODE_B and Node Date are transfered also to Flash ?
I know these are several questions, i need to know about this because if the nodes are transfered alwasy and with all node content transfered, then i will need to have minimum data in that nodes shared to WDA and even i will need to clear/refresh (object->invalidate) that nodes when Flash receives the data, this in order to have good performance and server work for the application.
Does somebody can give me some 'light' about this please ?
Best Regards
Frank

Hi Frank,
From my past experience with FlashIslands, what i understood is:
The context data is transferred from WDA to Flash whenever there is a change in any of the context nodes shared with Flash.
And when ever there is an event fired from Flash to WDA.
please find the answers for your questions below:
1. Yes all the node content will be transferred. Actually not only this node where you have made the change, but also all the nodes data which are shared with Flash will be transferred.
2. Yes. please see point 1.
3. Yes
4. As far as i know, No. As the change is in the content of a node which is not shared with Flash, there wont be any data transfer from WDA to Flash.
I hope this is clear!

How to extract Source from .wda file

Hi WebDynpro Experts,
Do you know how to extract source from .wda file. I appreciate your help and will award points for correct answers.
Thank you
Maruti CR

Hi,
U wont be able to extract source code from wda file.It contains
only class,xml and mf files.The only thing that u would be able
to use is class file which u need to convert to .java file
by .class to .java converter.
Hope this will clear ur doubt.Still if u want to try just extract
wda file using winzip.go on doing this untill u find unzip files.

BSP Doubts

Hi Experts,
Can anybody can explain to following doubts
1) Does the BSP htmlb library is ligther than the WebDynpro ABAP, I mean which page loads faster
2) Is Custom javscipts are supported in WebDynpro ABAP.
3) Is RTL Rendering can be controlled in WebDypro ABAP ?
4) Is there any client-side regular expressions can be used in the BSP ,otherwise cl_abap_regex is the only options to validate which will becomes a server side validation (ABAP Stack )
5) Is there any control of the BSP input elements if we declare data type as numeric, system should allow the numericals only
6) Can BSP HTMLB is supported by the Opera, Chrome and Safari browsers
7) How to handle the Back Page problem, everytime it is getting session out whenver tried using BACK page in IE.

Hi Naga,
the sort of questions you are asking require a good understanding of the underlying technologies to not only get the answers but to understand the implications of these answers as well.
I encourage you to "have a go". Roll up your sleeves and try everything you have asked about yourself. You will learn much more than the simple answers to these seven questions.
To start you on the way you should understand that the BSP runtime framework provides server-side scripting for the ABAP web application server. In this regard BSP applications can be seen as no different to .JSP, .ASP, PHP or any other similar model. The BSP runtime environment sits on top of the Internet Communication Manager (ICM). The provided tag libraries such as HTMLB execute on the BSP runtime. These tag libraries are typically used to produce HTML and Javascript code that is returned as part of the HTTP response to the web browser for rendering and execution by the browser. You do not have to use these tag libraries, or any others you build yourself, if you do not want to.
The WebDynpro ABAP runtime also sits on top of the ICM - but in most other respects is very different from the BSP runtime. At runtime a WDA application produces as a response a data stream (lets assume it is XML) that is passed to a purpose build renderer to produce the specific user interface elements for the client application. Most people are used to the WDA client being a web browser. As web browsers have varying and somewhat limited rendering capabilities the WDA renderer for a web browser runs on the server as part of the WDA runtime and translates the XML response from the WDA application into the appropriate HTML and Javascript before it is transmitted to the web browser. If the client application includes its' own WDA renderer the server simply transmits the XML datastream to the client application which then renders the UI itself. This is how the desktop version of NetWeaver Business Client works. It uses MFC libraries to render the UI natively on windows clients.
If you have absorbed the two paragraphs above you should realise a few things. Firstly you can send anything you like in the response to a HTTP request using the BSP runtime. Secondly you have essentially no control over the response you send to a WDA HTTP request.
So to quickly address your specific questions....
1) Does the BSP htmlb library is ligther than the WebDynpro ABAP, I mean which page loads faster
That would probably be true when your client is a web browser - it almost certainly would not be true if you were using the desktop version of the NetWeaver Business Client or the WDA Flex client.
2) Is Custom javscipts are supported in WebDynpro ABAP.
No
3) Is RTL Rendering can be controlled in WebDypro ABAP ?
Yes - I think. Have a go and find out.
4) Is there any client-side regular expressions can be used in the BSP ,otherwise cl_abap_regex is the only options to validate which will becomes a server side validation (ABAP Stack )
Sure - you can put any client-side code you like in a BSP response.
5) Is there any control of the BSP input elements if we declare data type as numeric, system should allow the numericals only
Sure - use client-side scripting to do this. Alternatively create your own BSP tag library to do this.
6) Can BSP HTMLB is supported by the Opera, Chrome and Safari browsers
The HTMLB tag library only supports specific browser versions. Check SAP documentation for these specifics. But you do not have to use these tag libraries and you can create your own if you like as well.
7) How to handle the Back Page problem, everytime it is getting session out whenever tried using BACK page in IE.
I assume you are talking about a stateful BSP application. This is a web browser issue. If you build a stateless BSP application you can prevent this and there are other techniques to prevent it with stateful pages as well. Personally I recommend avoiding stateful BSP applications.

Hi Saket,
Following will be required for created a custom business object.
1. Object Type - ZTEST (Internal Techincal Key)
2. Object Name - ZTESTNAME (Technical Key Name)
3. Name - TEST (Name of BO, it is used while selecting the object type)
4. Description - (Short Description of BO)
5. Program - ZTESTPROGRAM (ABAP program in which the methods of the object type are implemented)

PI' RFC Connection pool doubt.

Hi PI exports:
i have a doubt about pi' RFC Connection pool ,pi RFC receive channel can set the conn pool size ,but when start the rfc receiver channel ,is there always only one Connection pool ,or there is only one Connection pool instance?
thinks
Edited by: kevin liang on Oct 19, 2009 6:45 AM

Hi,
Connection poolins size means how many number of connection you want to make open to send data to ECC, We can define maximum number of connection in Receiver RFC Adapter,Go to additional parameters section and define Max Number of connection give the number there,thats it.Internally it works as Connection poolin mechanism.

Small Doubt Regarding SY-MANDT

Hi All,
     SELECT changenr FROM cdhdr CLIENT SPECIFIED INTO CORRESPONDING FIELDS OF TABLE it_cdhdr
                                         WHERE mandant = syst-mandt
                                         AND   objectclas = 'MATERIAL'
                                         AND   objectid   = wa_matl-matnr
                                         AND   tcode      = 'MM02'.
     I have written the select stament as shown above.
     In this i have a doubt like adding a field sy-mandt in the where condition will increase the Efficiency of program or not.
regards,
raghu.

Hi..
No doubt the efficency would be affected but from business point of view there will many things that need to be checked as in:
If you are viewing data from CDHDR and CDPOS which is client specific then you are not viewing complete data.
These tables give us and document changes made to a particular object in SAP but if anything is cross client like company code(lets assume) then changes to it wont be visible in all the clients..
so there can be some key information you can miss out while working on some of the objects.
else in this case its good to make query cross client.

Doubts with control break statements on internal table loops (AT/ENDAT)

Hi, i've had a couple of doubts for a long while which I hope someone can clarify today:
1) I know how to use the AT statements, however, i'm not sure I get correctly what this part of help regarding this commands means:
"The control level structure with internal tables is static. It corresponds exactly to the sequence of columns in the internal table (from left to right). In this context, the criteria according to which you sort the internal table are unimportant."
I've always sorted the internal table before the control break and it works that way. For example:
SORT ITAB BY EBELN EBELP.
LOOP AT ITAB.
AT NEW EBELN.
* Code for the order header
ENDAT.
ENDLOOP.
If I don't sort the internal table, it doesn't work! (i get dupplicated processing). In the example, if i have more than one register with the same EBELN and they're not consecutive, the header gets processed twice. I really don't get that part of the help text.
2) I know this: "At the start of a new control level (i.e. immediately after AT), the following occurs in the output area of the current LOOP statement:
All character type fields (on the right) are filled with "*" after the current control level key.
All other fields (on the right) are set to their initial values after the current control level key."
My doubt is: WHY is that this way? Because sometimes (most times) I need those fields INSIDE the statement! So when that happened i've solved it in one of three ways:
LOOP AT ITAB INTO WA_ITAB.
WA_ITAB_AUX = WA_ITAB.
AT NEW FIELD.
 WA_ITAB = WA_ITAB_AUX.
* ...Rest of the code for the first register
ENDAT.
ENDLOOP.
LOOP AT ITAB INTO WA_ITAB.
AT NEW FIELD.
 READ TABLE ITAB INDEX SY-TABIX INTO WA_ITAB.
* ...Rest of the code for the first register
ENDAT.
ENDLOOP.
* (Without AT)
LOOP AT ITAB INTO WA_ITAB.
IF WA_ITAB-FIELD <> FIELD_AUX.
 FIELD_AUX = WA_ITAB_FIELD.
* ...Rest of the code for the first register
ENDIF.
ENDLOOP.
Is there any problem with this way of coding? Can be done better?
Thank you very much in advance.

Hi..,
1)
See if u sort the table on a field on which u r using AT ENDAT .. then all the records which are having the same value for that field will form a group or those reocrds will be at one place.. so when u sort the table for all the records AT ENDAT will get executed onli once..
If u dont sort this table on this field then all these records will be at different places and in between there may be records with different value for this field.. so this AT ENDAT will get executed for each record !!
2)
No u cannot use the Right hand fields of the field in the table .. Because these AT events work as Group based operations... So till that field on which AT ENDAT is working it breaks that record into two groups.. One is the left hand fields including that field.. and right hand fields as another group.. and makes the right hand group as stars ****. Thats y u can observe that even any one field in the left hand group changes the AT ENDAT will get executed !!!!
Hope u understood !!!
