Dynamic Screen Paramater Generation

Is it possible to generate parameters for a screen on the fly??
im trying to create a generic program that can adapt selection option parameters depending on a database table.
ie if the user asks to search for an item in a table, they will be provided with a dialog containing dynamic parameters for each field in the table.
tried this using field symbols but the compiler will not let me.
ie:
for all fields in table
parameters: <pname> type <ptype>.
is it possible to generate code for a form and call it at runtime??

Yes, it is. But the statements are not released for customer use and they will not be supported by SAP. If you would like an example program, email me at my email address on my business card.   Here is another way of doing it using a POPup.
report zrich_0001 .
data: ivals type table of sval with header line.
data: x_matnr type mara-matnr,
      x_vbeln type vbak-vbeln,
      x_edatu type vbep-edatu.
start-of-selection.
ivals-tabname = 'MARA'.
ivals-fieldname = 'MATNR'.
append ivals.
ivals-tabname = 'VBAK'.
ivals-fieldname = 'VBELN'.
append ivals.
ivals-tabname = 'VBEP'.
ivals-fieldname = 'EDATU'.
append ivals.
call function 'POPUP_GET_VALUES'
    exporting
*   NO_VALUE_CHECK        = ' '
      popup_title           = 'Enter Values'
*   START_COLUMN          = '5'
*   START_ROW             = '5'
* IMPORTING
*   RETURNCODE            =
    tables
      fields                = ivals
   exceptions
     error_in_fields       = 1
     others                = 2
read table ivals with key fieldname = 'MATNR'.
if sy-subrc = 0.
    x_matnr = ivals-value.
endif.
read table ivals with key fieldname = 'VBELN'.
if sy-subrc = 0.
    x_vbeln = ivals-value.
endif.
read table ivals with key fieldname = 'EDATU'.
if sy-subrc = 0.
    x_edatu = ivals-value.
endif.
write:/ x_matnr, x_vbeln, x_edatu.

Dynamic crystal report generation - issues with column headings

Hi All, 
I'm trying to generate a crystal report dynamically based on a "result set" data(Query: select REPORT_ID, REPORT_NAME, REPORT_DESC, RPT_FILE_NAME, LOCATION from IRS_REPORT_DETAILS). I'm able to generate the report run time, But the report is without columns heads. I would like to include the column headings as well. 
I searched the API(RAS) and found that there is a 'add(java.lang.String fieldName, java.lang.String headingText) " method present in "ReportObjectController" using which we can add the headings. 
ReportDefController reportDefController = clientDoc.getReportDefController();
ReportObjectController reportObjectController = reportDefController.getReportObjectController();
reportObjectController.add( "{Table.Field}", "FieldName" );
 
I'm facing problems in using this code. When trying to use this function for my fields(Ex: reportObjectController.add( "{ IRS_REPORT_DETAILS.REPORT_ID}", "Report ID" );) it is giving me the following error: "com.crystaldecisions.sdk.occa.report.lib.ReportSDKGroupException: The field was not found.---- Error code:-2147213310 Error code name:fieldNotFound" 
The following is my dynamic crystal report generation code: 
public ReportClientDocument execute(String repName, String query) {
 ReportClientDocument boReportClientDocument = null;
 try {
 boReportClientDocument = new ReportClientDocument();
 boReportClientDocument.newDocument();
 // Add a table based on the given Resultset to the report.
 dbConnResultSet mySampleResultSet = new dbConnResultSet();
 //mySampleResultSet.execute(query);
 boReportClientDocument.getDatabaseController().addDataSource(
 mySampleResultSet.execute(query));
 IReportSource test = boReportClientDocument.getReportSource();
 // Access all the database fields
 DatabaseController databaseController = boReportClientDocument
 .getDatabaseController();
 IDatabase database = databaseController.getDatabase();
 Tables tables = database.getTables();
 ITable table = (Table) tables.getTable(0);
 int NO_OF_FIELDS = table.getDataFields().size();
 int LEFT_POSITION = 200;
 // Add all the database fields to the report document
 for (int i = 0; i < NO_OF_FIELDS; i++) {
 IField field = table.getDataFields().getField(i);
 FieldObject fieldObject = new FieldObject();
 fieldObject.setFieldValueType(field.getType());
 fieldObject.setDataSource(field.getFormulaForm());
 IReportObject rep = (IReportObject) fieldObject;
 IObjectFormat objformat = rep.getFormat();
 objformat.setEnableCanGrow(true);
 objformat.setHorizontalAlignment(Alignment.from_int(1));
 rep.setFormat(objformat);
 rep.setLeft(LEFT_POSITION);
 rep.setWidth(1000);
 LEFT_POSITION = LEFT_POSITION + 1000 + 50;
 ISection section = boReportClientDocument
 .getReportDefController().getReportDefinition()
 .getDetailArea().getSections().getSection(0);
 //***************** Data being added to the report here, But headings are not added*****************
 boReportClientDocument.getReportDefController()
 .getReportObjectController().add(rep, section, i);
 boReportClientDocument.createReport();
 /*Some report saving code is present down*/
 } catch (ReportSDKException ex) {
 ex.printStackTrace();
 } catch (Exception ex) {
 ex.printStackTrace();
 return boReportClientDocument;
 
appreciate your help.

IField field = table.getDataFields().getField(i);
Here you are getting the first field in the array. This may not be the field you want to add since we aren't sure how the arrays are ordered when retrieving fields from the report. It is better to retrieve the fields with the findObjectByName method, thus ensuring you are retrieving the field you want to add to your heading.

Dynamic screen field values

Hi,
One quick question, I have created a screen with reference to a custome table fields and it is working fine. When I enter values for the first time, the values look ok in debug but when I change the values on the screen, the new values are not updated in the screen fields in debug. Old values are shown in the debug.
I guess there is some kind of logic to do this. Like using the dynamic screen fields read or ....
Can someone help me on this?
Regards,
Roopesh Singh

hi there...
when u first enter the values, they get into the work area related to the screen fields.....
but when u change the values, they dont get changed in the workarea associated with the fields. since the data does not get updated in the fields, it wont show in the debugging mode. so chk ur code and make sure u update the data in the variables associated with the fields.
do reward if helpful or get back with further queries.

Dynamic Screen Resolution

Hello Everyone!!! I am having tough times solving query on Dynamic Screen Resolution in J2ME. How can you create an application in J2ME that automatically adjusts to the screen resolution to the phone it is being installed. That means if the resolution is small the layout automatically adjusts to the screen resolution and if its bigger then accordingly... Please help....

If you can use a UI framework/toolkit I suggest LWUIT. If not, code using proportions. Avoid absolute values of x, y, width and height. I made a sample at http://smallandadaptive.blogspot.com/2010/12/bar-chart.html

Dynamic screen generation

Hello everybody. I have to generate new screen and fields on it at runtime. Does anybody know how to do this?

I had implemented similar thing 6 months back.
I am giving some guideline to fulfill your requirements.
1. There will be include in your main program, say ZMAIN which will be filled by another program, say ZCONTROL.
2. You will fill include (which will contain dynamic code for your selection screen) in ZCONTROL and submit ZMAIN from ZCONTROL
REPORT ZMAIN.
include zdyn_screen. (include it in your main program)
Report ZCONTROL.
data : gt_code TYPE TABLE OF string,
wa_code type string,
c_prog type sy-repid.
wa_code = 'Parameters : test type matnr.'.
append wa_code to gt_code.
c_prog = 'ZDYN_SCREEN'.
insert report c_prog from gt_code.
commit work.
SUBMIT ZMAIN AND RETURN.
* Clear up the screen as you exit.
REFRESH GT_CODE.
READ REPORT C_PROG INTO GT_CODE.
* You may insert some check if your want OR you can omit the step of reading report
refresh gt_code.
insert report c_prog from gt_code.
Remember, you may need much more logic to handle various scenarios.
To get the text from your dictionary field for your selection screen parameters / select-options you can also use code
INSERT TEXTPOOL
To check syntax before inserting code into your include, you can try SYNTAX-CHECK or use FM EDITOR_SYTAX_CHECK.

Regd. Dynamic Screen Generation

Friends,
I hava a requiement like i will receive the input parameters from the called function, so appropriate screen has been generated along with the input parameters. How to do that ?
Thanks.
Hitesh Shah

Hi,
This FM SWY_CREATE_DYNPRO is available in 4.7 onwards.
If you want to display the screens conditionally,
you can create as many screens required in screen painter and then call those according to requirement.
e.g.
if cond1 = true
call screen 100.
else.
call screen 200.
endif.

Dynamic screen update options?

We have a complex web-based user interface that is rendered using XSLT from a J2EE application. Each screen consists of lots of HTML fields, some of which are grouped together into what we call "multi-row blocks". A new block can be added by pressing a "+" button.
What our customers would like is that new blocks are added without the screen refreshing or changing. We used to have a JavaScript/Dynamic HTML solution that would do the complex HTML manipulation needed (insert new sections of HTML and re-name any fields in following blocks) but this was:
- very specific to IE 6's internals (it's manipulating how IE internally represents HTML, which can be different to the output of the original XSLT transformation);
- a couple of thousand lines of very brittle code, generally driven by regular expressions that kept breaking;
- was unacceptably slow for large screens (more than a 20-ish blocks)
To get around this we re-worked it to do a full server round-trip, using HTML Anchor tags to return the user to the start of the new block.
However, Internet Explorer has a very annoying bug that it refreshes the screen, shows the top of the form, then after a couple of seconds it then "bounces" down to the anchor position.
Does anyone know how we can get around this anchor problem? Or a better way to fix the solution, avoiding the screen refresh?
Our customers have recommended using AJAX, but that doesn't get around the problem of making a large amount of updates to the current HTML form, so would do little to help us?
Thanks,
Chris Nappin.

AJAX is really just a cadillac solution on top of your html DOM manipulation. In your case, if the client side can decide how to modify itself when the plus button is added, then ajax would just be overkill.
DOM manipulation while ugly is still probably your best bet.
AJAX, beyond what you have done already, just allows you to make server calls to get data without reloading the page. As it seems you don't need new data, ajax wouldn't help.

The above is an executable program.
zcl_test_alv is a class which u need to create in se24 according to ur requirement
u need to define methods and attributes.

Dynamic Screen layout

Hi all,
I have to display fields dynamically based on certain conditions,so i started with grouping certain fields in several subscreens like this.
subscreen A
subscreen B
subscreen C
Now if for certain type of conditions i'll be displaying subscreen A and subscreen C next to that ,like subscreen C should move up to the palce of subscreen B and subscreen B will not be displayed.(so all combination of the three screens,without
any empty space inbetwen them).Wondering how to go abut that.
Is there screen flow command which calls subscreen conditionally based on 'IF' conditions and how to move screens/fields up from its original locations.
Thanks in advance,
dan.

Ok Dan, I've spent the last view minutes putting together an example, which works quite well. Here is the main program code.
REPORT zrich_001.
DATA: v_suba TYPE sy-dynnr.
DATA: v_subb TYPE sy-dynnr.
DATA: v_subc TYPE sy-dynnr.
PARAMETERS: p_suba AS CHECKBOX.
PARAMETERS: p_subb AS CHECKBOX.
PARAMETERS: p_subc AS CHECKBOX.
CALL SCREEN 100.
*&      Module PBO OUTPUT
*       text
MODULE pbo OUTPUT.
*set pf-status 'Main'.
IF p_suba = 'X'.
    v_suba = '0101'.
ENDIF.
IF p_subb = 'X'.
    IF v_suba IS INITIAL.
      v_suba = '0102'.
    ELSE.
      v_subb = '0102'.
    ENDIF.
ENDIF.
IF p_subc = 'X'.
    IF v_suba IS INITIAL.
      v_suba = '0103'.
    ELSEIF v_subb IS INITIAL.
      v_subb = '0103'.
    ELSE.
      v_subc = '0103'.
    ENDIF.
ENDIF.
IF v_suba IS INITIAL.
    v_suba = '9999'.
ENDIF.
IF v_subb IS INITIAL.
    v_subb = '9999'.
ENDIF.
IF v_subc IS INITIAL.
    v_subc = '9999'.
ENDIF.
ENDMODULE.                 " PBO OUTPUT
*&      Module pai INPUT
*       text
MODULE pai INPUT.
CASE sy-ucomm.
    WHEN 'BACK'.
      LEAVE PROGRAM.
ENDCASE.
ENDMODULE.                 " pai INPUT
Of course, you can put your own gui status and other stuff in here, but you get the idea. Here is the screen flow logic of screen 100.
PROCESS BEFORE OUTPUT.
MODULE pbo.
CALL SUBSCREEN subsa INCLUDING sy-repid v_suba.
CALL SUBSCREEN subsb INCLUDING sy-repid v_subb.
CALL SUBSCREEN subsc INCLUDING sy-repid v_subc.
PROCESS AFTER INPUT.
MODULE pai.
CALL SUBSCREEN subsa .
CALL SUBSCREEN subsb .
CALL SUBSCREEN subsc .
Now on screen 100, there are three subscreen areas, called SUBSA, SUBSB, SUBSC. Also in this program there are three subscreen dynpros, called 101, 102, and 103. So all this will need to be created to make this example work.
Now you can see in the PBO, that I am dynamically assigning the subscreen numbers to the subscreen area variables depending on what you select on the selection screen. Also, it is important to assign a dummy subscreen(with nothing in it) to any subscreen area which has not been assigned a real subscreen. So you see that I am assigning subscreen 9999 for this.
Hope this helps.

Rich Heilman

Dynamic Screen Problem

Hi,
I've created a cl_gui_container at the outter screen's initialization.Later I want to
add some something like a box into this container area, and build the content
of this box dynamicly,eg (add several box and label on it) ,how can I do it,
Thanks

Hi Ray,
Please use function RPY_DYNPRO_INSERT.
add your required UI elements in the parameter 'fields_to_containers'.
Be careful to understand the table contents before you use the function.
