Differences between controller/view & pages with flow logic

Hi experts!!
I am trying to create a BSP using the SBOOKSHOP tutorial.
What i have not understood so far is the differnce between creating a bsp with pages with flow logic,
and using the controller/ view method.
When should we use the first and when the other approach??
Any link to documentation would be appreciated!
Thank you!!

Hi Grigoria Koutsogianni,
I hope the older thread on the same topic could help you understand the difference!

Page With Flow Logic x Views

Hi Guys,
What is the main difference between working with Page with flow logic and Views? I mean, I may build up my site using only Page with flow logic or just using Views, so Why should I use views or Page w/FL or Both?
Thank you in advance,
Alexandre

Hi ACR,
You can build your application using only flow logic but not ONLY with views..
Take a look at below threads for difference in MVC and Flow logic methods...
[Difference in MVC and Flow logic 1.|Re: diffrence between MVC and Classical Bsp application]

In MVC, do i need a View or Page with flow logic for POPUP window

Hi All,
I have the below scenario using the MVC pattern.
I have a main view with 3 trays, each tray has two buttons, for example first tray has Create Order button. When I click on this button, I need a popup window to come with a tableview and a button(Create), where I select some rows and click on the button Create to create order.
But as per the MVC pattern I canu2019t call the view (popup) from another view(main view). So should I create a VIEW or PAGE WITH FLOW LOGIC for the popup? .
I need 6 popup to be called from the main view and once the function is done close the popup.
Please suggest me the flow for this scenario.
Cheers,
Srini.

Srini,
1. You can call the view in pop-up because you will be calling the controller using open.window.
Here is the sample code:
method DO_REQUEST .
data:
        li_vw           type ref to   if_bsp_page,
        lv_form_field   type          string,
        li_md           type ref to   zcl_model01.
dispatch_input( ).
li_md ?= get_model( 'm01' ).
lv_form_field = request->get_form_field( 'invoice_create' ).
if lv_form_field is initial.
*------ Request to display main page
    li_vw = create_view( view_name = 'main.htm' ).
    li_vw->set_attribute( name = 'model' value = li_md ).
    call_view( li_vw ).
elseif lv_form_field eq 'true'.
*------ Request to display Invoice page in pop-up
    li_vw = create_view( view_name = 'invoice.htm' ).
    li_vw->set_attribute( name = 'model' value = li_md ).
    call_view( li_vw ).
endif.
endmethod.
Layout:
      function do_Invoice()
      { var s=0; r=1; w=300; h=300; x=screen.width/2;
        x=x-w/2;
        var y=screen.height/4;
        y=y-h/2;
        popUp=window.open('main.do?invoice_create=true','win','width='+ w
        +',height='+ h +', left=' + x +',top='+ y +');
Option2:
Ofcourse you can't bind the model in page becos those are 2 different things. But all you need to do is access the model to get some value. To know how to access the model from Page w/flow logic look at [this link|Passing model reference to a page in a Popup].

Calling a page with flow logic from a controller

Is there any possibility of calling a page with flow logic(x.htm ) from a controller?
Also I want to know how to apply scrolling to a tableview in a View as there is no event handler here. Iam able to view the first 30 records but want to navigate from 31 to 60...61to 90 and so on.......
Thanks and regards,
Sinu

Thank you so much...
but will I be able to call from a controller as we call a view...similar to the below code.
lref_first_view = create_view( view_name = 'first.htm' ).
lref_first_view->set_attribute( name = 'MODEL' value = mref_model_first ).
call_view( lref_first_view ).
I have already set the visibleRowCount....but my issue is to navigate to the next records i.e say 2nd page 3rd page..........

Hpw tp call a 'Page with Flow Logic' from within a View

Within the same BSP, I have the requirment to call a page in the ;Page with Flow Logic' section from a page in the 'View' section.
Is this possible and if it is, how do I do it? I have tried some calls but they all have failed.
Thanks
Glenn

in the view you want to navigate then try
<bsp: call > or <bsp: goto> htmlb tags. or else you can use window.open method and open in a new window.

Xhtmlb: tabStrip - how to execut a page with flow logic

Hello all, how do I execute a "page with flow logic" from a "tabStrip". Currently I am using a "page fragment". But I need to change to a "page with flow logic" becuase of a technical issue.
Is it possible to tell which tab was selected using event processing? When I try, I am getting "illegal reference".
Here is a sample of my current code.
<xhtmlb:tabStrip id            = "TABSTRIP"
                 viewState     = "EXPANDED"
                 viewStateMode = "COLLAPSED_EXPANDED"
                 tooltip       = "Choose tab" >
<xhtmlb:tabStripItem name = "Home"
                       title = "Home" >
    <%@include file="home.htm" %>
</xhtmlb:tabStripItem>
<xhtmlb:tabStripItem name = "Medical"
                       title = "Medical" >
    <%@include file="medical.htm" %>
</xhtmlb:tabStripItem>
<xhtmlb:tabStripItem name = "Dental"
                       title = "Dental" >
    <%@include file="dental.htm" %>
</xhtmlb:tabStripItem>
<xhtmlb:tabStripItem name = "Vision"
                       title = "Vision" >
    <%@include file="vision.htm" %>
</xhtmlb:tabStripItem>
<xhtmlb:tabStripItem name = "FlxSpnd"
                       title = "Flexible Spending" >
    <%@include file="home.htm" %>
</xhtmlb:tabStripItem>
<xhtmlb:tabStripItem name = "Other"
                       title = "Other" >
    <%@include file="home.htm" %>
</xhtmlb:tabStripItem>
<xhtmlb:tabStripItem name = "RevSub"
                       title = "Review and Submit" >
    <%@include file="home.htm" %>
</xhtmlb:tabStripItem>
</xhtmlb:tabStrip>
What would I replace the "page frament" with?
Thanks in advance for your help, Troy

Hi Troy,
If i understood your requirement i think you need to move to other pages or views when the tabstrip items or clicked. If your requirement is the above one below is the explanation....
In the layout you include a attribute onSelect        = "mySelect" in the tag xhtmlb:tabStrip.
For event handling in the oninputprocessing you write the below code,
   CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
DATA: TABSTRIP TYPE REF TO CL_XHTMLB_TABSTRIP.
Reading Data from Toolbar
TABSTRIP ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST = REQUEST
                                        NAME    = 'xhtmlb:tabstrip'
                                        ID      = 'tb3' ).
Optional: test that this is an event from HTMLB library.
IF EVENT_ID = CL_HTMLB_MANAGER=>EVENT_ID.
Scenario 1: Read event from manager.
DATA: EVENT TYPE REF TO IF_HTMLB_DATA.
EVENT = CL_HTMLB_MANAGER=>GET_EVENT_EX( RUNTIME->SERVER->REQUEST ).
DATA: request_event TYPE REF TO cl_xhtmlb_event.
request_event ?= event.
IF EVENT IS NOT INITIAL AND EVENT->EVENT_NAME =
CL_XHTMLB_TABSTRIP=>CO_EVENT_NAME.
*---here you can handle the event...
ENDIF.
ENDIF.

Fill select-options in Page with flow logic ???

Hello All,
          I created a BSP Application using Page with Flow Logic.
In the first page of my Application I'm using 2 input fields as select-options.
Now I'm populating a Ranges of that Field using the type :-
selopttab
I populated the ranges table like :-
wa_bname_sel-sign   = 'I'.
          wa_bname_sel-option = 'BT'.
          wa_bname_sel-low    = '*'.
          wa_bname_sel-high   = 'Z'.
        ELSE.
          wa_bname_sel-sign   = 'I'.
          wa_bname_sel-option = 'EQ'.
          wa_bname_sel-low    = p_bname.
          wa_bname_sel-high   = p_bname.
        ENDIF.
        APPEND wa_bname_sel TO p_bname_sel.
        CLEAR wa_bname_sel.
But the problem is I checked the corresponding DATABASE Table entries by passing thesame value .
i.e I passed the low and high values to the field as '*' and 'Z'.
The total number of entries differ when passing '*' and 'Z' to when passing SPACE.
I tried even with contains Pattern .This time the total number of records fetching has Increased but the sum is not exact when passed SPACE to the Database Table.
So what should I pass to the Low and High values of my Ranges Table to get all the entries ????
DOes this type of building the Ranges work in BSP's ?
How are u people working out for the select-options functionality in Page with flow logic ?

Calling a BSP page with flow logic from LAYOUT

Hello all. I am developing a BSP transaction to update HR data on SAP. I initially developed this with one 'page with flow logic' and several 'page fragment's. It has been suggested that I break this out into several pages with flow logic because the code in the 'OnInputProcessing' Event Handler was getting quite complicated. I was using the BSP directive to execute my 'page fragments'. This was very simple to do. What do I replace the BSP directive to call a page fragment with in order to call a page with flow logic. I have included the code below. I have converted the 'body.htm' 'page fragment' to a 'page with flow logic' and I am not sure of the correct way to call the page. I do not have access to the navigation->goto_page( 'body.htm' ) at this point. I am new to BSP and appreciate any help offered.

Hi,
uhmmm, as it was previously suggested, you should perhaps think about MVC for your development. Working with classes and methods gives you more room for a better looking code. But at this point I´m not sure where your real problem is. You mentioned first that you created one page with logic and several page fragments and then you are worried because the code in the OnInputProcessing event is getting out of control
First, you cannot insert a page in a page. You can only insert fragments in a page with <%@include file="header.htm" %>.
Second, if you don´t have idea of MVC or you don´t want to switch to MVC, then create a modules program (SE38) where you´ll enter your code as subroutines and you call these subroutines from OnInputProcessing as follows:
perform subrout1 in program XXXXXX tables YYYYY using AAAAA.
In your programm XXXXX you declare the code as:
form subrout1 in program XXXXXX tables YYYYY using AAAAA.
This can be a substitute to classes and methods.

Difference between INLINE view and WITH clause

Can anyone plz explain me about the performance difference between the below queries?
Query using INLINE view:
SELECT e.ename AS employee_name,
dc.dept_count AS emp_dept_count
FROM emp e,
(SELECT deptno, COUNT(*) AS dept_count
FROM emp
GROUP BY deptno) dc
WHERE e.deptno = dc.deptno;
Query using WITH clause:
WITH dept_count AS (
SELECT deptno, COUNT(*) AS dept_count
FROM emp
GROUP BY deptno)
SELECT e.ename AS employee_name,
dc.dept_count AS emp_dept_count
FROM emp e,
dept_count dc
WHERE e.deptno = dc.deptno;

Here's another one:
http://www.oracle-base.com/articles/misc/WithClause.php
And, here on this forum you will see that the WITH-clause is heavily used by all of us in order to generate some sample data (when OP's don't care to post CREATE TABLE + INSERT INTO statements).
The WITH clause enables you as well to 'pretend' you have a table and demonstrate a solution very quickly, without doing actual DDL .
As for the performance difference:
We would need to know your database version and many other things.
See:
HOW TO: Post a SQL statement tuning request - template posting
for step by step instructions you can (and should) explore yourself.

Open a pop-up in the OnInputProcessing part of a web page with flow Logic

Dears all,
System used : SAP WebAs 6.20
I have a html page in my project where every user can choose some options with radio buttons. When the user choose something, he click on a button which send us in the OnInputProcessing part of the page.
In the OnInputProcessing, we will do a CALL FUNCTION. If the result is Ok, we must display a pop-up with only a OK button.
From the layout part of the page, I display a pop-up with success using this code :
SCRIPT language=javascript
   function ConfirmMessage() {
       var bflag = confirm("Are you sure that you want to confirm your offer ?")
       u2026
/SCRIPT
FORM
   <input type = "submit" onClickMethod="ConfirmMessage()" name="onInputProcessing(post)" value="Confirm">
/FORM
But I can't call this code form the OnInputProcessing. I try with the functions of the class : CL_JAVA_SCRIPT too, but nothing is displayed.
Someone can help me ?
Best Regards,
Nelson

Difference between validation and susbstittution with tcodes

hi all can any body tell me about difference between validation and susbstittution with tcodes

Hi,
Settting up the FI Validations
You can use additional validation to supplement the existing SAP logic to fit you into your businness needs.
For e.g. to allow postings from company code 0001 to business area AA only.
GGB0 - To maintain the validations
Validation - Enter a validation name e.g. VBUS
Applicaion Area - SAP module e.g. FI
Calling Point - Dependent upon the application area that is selected.
0001 - Document Header - validate enteries at document header, e.g BKPF table
0002 - Line Items - check line item entris within a document, e.g. BSEG table
0003 - Complete Document - check settings for the whole documents.
e.g. Validation step 001
Allowed company code '0001' to post to business area AA only. 'FI00' checks that line item is from FI.
If checks failed, the error message number 14 is displayed to stop the transaction.
Prerequisite
<BSEG> $BUKRS = '0001' AND
<BKPF> $GLVOR = 'FI00'
Check
<BSEG> $GSBER = 'AA'
Message
Type E No. 14 - Business Area not allowed for company 0001
Output fields 1 - BSEG - GSBER 2 - BSEG - BUKRS
3 - 4
OB28 - Define Validations for Posting
CC CallPnt Validation Description Activtn Level
0001 2 VBUS Business Area Validation 1
Activtn Level - 0 - Not Active 1 - Activated 2 - Activated for all except batch input
GGB4 - Manage the activation of all validations in the SAP system.
Validations, Substitutions, and Rules
Purpose
With the validations and substitutions software, you can validate and/or substitute data at the time of entry in the FI-SL System and other SAP Systems.
Implementation Considerations
You do not need to change the standard system to customize your validations and substitutions. For each installation, you can define exactly which validations and substitutions are necessary to ensure the integrity of your data.
Features
Validation
In the SAP System, almost all input values are validated by a program or against tables or master files. Since some types of validations cannot be standardized, you can use FI-SL's validations program to create validations for your system.
With validations, you can check values and combinations of values as they are being entered in the SAP environment. Validation rules are stored in the Rule Manager; as data is entered, the Integration Manager validates the data against the validation rules stored in the Rule Manager. Because data is validated before it is posted, only valid information enters the FI-SL System.
You define validation rules using Boolean logic. When you define a validation rule, the system checks the validation rule to ensure that it is syntactically correct.
You can also define the result of breaking the validation rule. For instance, you can specify that a message is issued but the user can continue processing. You can also force the user to correct the error before processing can continue.
For more information, see Validation or What Are Validations?. For more information on using validations, see Creating a Validation. For more information on Boolean Logic, see Introduction to Boolean Logic.
Substitution
Substitution rules are stored in the Rule Manager. When data is entered in the system, it is substituted by the Integration Manager. The Integration Manager calls the Rule Manager. Substitution occurs before the data is posted to the FI-SL databases.
You define substitution rules using Boolean logic. When you define a substitution rule, the system checks the substitution rule to ensure that it is syntactically correct.
For more information, see Substitution or What Are Substitutions?. For more information on using substitutions, see Creating a Substitution. For more information on Boolean Logic, see Introduction to Boolean Logic.
Rules
A rule is a Boolean expression that you can use as a condition, as a check, or in another rule. Rules enable you to refer to frequently used Boolean statements simply by specifying the rule name.
The FI-SL Integration Manager uses Boolean logic. When you use Boolean logic and syntax, you can:
Validate data
Substitute data
Select ledgers for posting
Transfer substitution data to a rollup ledger
Select report data
The Rule Manager stores the Boolean rules used to analyze data. The Integration Manager calls the Rule Manager and determines whether entered data should be used. If a Boolean statement is true, an action is taken; if a statement is false, no action is taken.
Boolean logic is used in the following FI-SL modules:
Validation
Substitution
Ledger selection
Report Writer
Rollups
To use Boolean Logic in one of the functions listed, you create statements that are used as formulas in the FI-SL System. For more information on using Boolean Logic, see Introduction to Boolean Logic or Boolean Logic Statements and Rules.

Difference between saved views & workbooks

Hello,
I still cannot see what is the technical difference between a view and a workbook. When is one used over the other? Both contains saved results.
Pls could help enlighten.
regards,
Pascal

hi kishore,
We use workbooks for excel formating,like font changes, lay out changes etc...
Workbooks into which queries are inserted are no different in appearance than other Excel workbooks.
They can be saved as files, copied, sent and (using Excel functions) edited however you like and even supplemented with other data.
Views are primarily used for BW Web Reports, it is similar to the concept of workbooks is for BEx.A local view can be accessed only within a workbook in which it was saved, where as a global view can be accessed globally in the system, it is not attached to a workbook. Only Global view can be used in BW Web Templates.
u can seee the help doc for more details:
