Dvt:map - Example of displaying line geometry ?

Hi all,
Does anyone know of an example that shows how to display themes that contain line geometry objects (e.g. delivery routes, bus routes etc.).
All the examples I've found so far only show how to display points or polygons (areas).
I tried to use a predefined theme but ran into another problem:
Re: dvt:map - how to use a predefinedTheme with bind variables

Hi Robert,
Thanks for your immediate response.
My requirement is some how different from yours. In our case, there are certain graphs generated using Map Builder tool & are avaiable through the Data Source.
So, i need to integrate the base maps with UI. Im able to do that independently.
Now, my requirement is to changing the map dynamically while doing zoom in. Lets say, i have 3 maps. which are Area level, Region Level & Building Blocks Levels.
For each category i have a map. Initially, i need to display the Area level map...while doing the zoom in, depends upon the zoom in level i need to change the map dynamically to Region Level map. Similarly with Building block level.
I tried to do this from the backing bean by getting the Map Component & by getting the zoom level changing the property value of the map to region level map.
But the attribute "selectionListener" of <dvt:map component is not working for me. Hence got strucked here...Do you have any sugestions on this how easily we can do this.
Help me in this regard.
Thanks,
Konjeti

How to display line items twice in a single page in sap script

HI,
I am working on check printing. I copied the standard driver program and form to Zprogram and ZForm. Which are RFFOUS_C(print program) and F110_PRENUM_CHECK(Form Name).
I want to display the line items twice in the same page and sub sequent pages.
Currently I am able to display line items only once.
Example:
PAGE1.
line item1
line item2
line item3
line item4
line item5
line item1
line item2
line item3
line item4
line item5
line items 1 to 5 which are in main window.
How to achive this problem.
Regards,
vinod

Hi
I had the same request for a check form in Canada. I solved it by writing the line item output into variables and print these variables in a second window. It was ~10 hours of effort, not a real nice technical solution but it worked.
If you require I can send you a PDF of the sap script form definition. You can contact me at [email protected] Answers can take 1 week or more.

Displaying line items, although not activated in FS00

Hi everyone!
I've got a question about line items.
I had created a GL account, and in it's master record I didn't activated Display line item. But, when I call transaction for displaying GL account's line items (FAGLL03), I can see line items?
How is that possible?
I know that there are some special cases, for example expense accounts: for every expense account there is a cost element in CO, and no matter settings in FS00, for expense account there is always line item display. Similary, reconciliation accounts always have open items management, irrespective of settings in FS00.
But this is just regular account, with very few settings in master record: its balance sheet account, the account currency is local currency, sort key 001 and field status group G001. And that's all.
Can somebody explaine this?

Guys. In addition to above my problem. I was facing this problem due to some graphics issue on my laptop. I was not able to see most of the fields because of Graphics Driver installed on my laptop. ( Later on I got this solution. ).
This seems very unrealistic to hear but my experience is true.
I hope in future if some one will have this issue please check out driver compatibility specially Graphics. This problem may suppose to encounter with Dell.
Anyways Z layout also worked fine as suggested by Guest FICO.
Thank you all.

Number of displayed lines in a table

Hello colleagues,
We are using a table with a master column (tree). Additional we are using an input field where a user can enter a number so that the displayed lines can be change at runtime.
Problem:
I would like to know the displayed number of lines as it is displayed in the button line of the table in the view (where a user can jump direct to a line) - but I do not know how I get it.
Question:
How do I get the content of the max number of available lines in the button of the displayed table?
Thanks+greetings,
Achim

Hey Maheswaran.B,
thanks for the reply - the problem is not solved with the suggestion (because I do not get the maximum number of line displayed).
I did the following:
On the very first time if "modifyView" will be executed I do a loop over the table. If the maximum number is reached within the loop I set this number - if not I set the number of loops.
Here is a code example:
   DO 10 TIMES.
      ADD 1 TO l_counter.
      CLEAR elem_tabletree.
      elem_tabletree = node_tabletree->get_element( index = l_counter ).
      IF elem_tabletree IS INITIAL.
        SUBTRACT 1 FROM l_counter.
        EXIT.
      ENDIF.
    ENDDO.
*--- set the value to the bound variable
    elem_owner_node->set_attribute(
      EXPORTING
        name = `NUMBER_OF_LINES`
        value = item_number_of_lines ).

Map app not displaying correctly

I recently downloaded the most recent os 8.1.3 on my iphone 4s. Now the map app (apple default) doesn't display correctly. I only see the grid and my location dot in standard view, no street names or lines, no details whatsoever. This is affecting any app that uses the apple default (Zillow, trulia, etc). My husband has the exact same iphone 4s and he has the most current os and his map app works fine. I'm thinking that I should try to reload the most current os but since it is the most current, there doesn't seem to be an obvious way since all message are "you have the most current version". I could also try to download just the most recent version of the map app but since it is a default, I don't know how. Any suggestions?

Hi meedjmom,
If you are having issues with your Maps application not displaying correctly, you may want to try some things to troubleshoot.
First, quit all running applications and test again -
Force an app to close in iOS
Next, I would try restarting and if needed resetting the iPhone -
Restart or reset your iPhone, iPad, or iPod touch
If the issue is still present, you may want to restore the iPhone as a new device -

How to use Google Maps with dvt:map ?

http://www.oracle.com/technology/software/products/mapviewer/text_files/mapviewer1112_readme.txt
http://www.oracle.com/technology/software/products/mapviewer/index.html
Native support of Google Maps and Bing Maps API. You can now display
Google and Bing maps natively in your Oracle Maps (JavaScript)
applications. Please check out the online Oracle Maps JSDoc API on
how to use the new classes.Unfortunatly it looks like it's not possible with dvt:map
http://download.oracle.com/docs/cd/E15523_01/apirefs.1111/e12418/tagdoc/dvt_map.html
It's an important requirement for our project and probably for many ADF customers.
I would like to know if :
Is there any way to use Google Maps with dvt:map ?
Otherwise, is there any plan to support it ? Should we expect it within a year ?
Else, I think we will use directly the Javascript Oracle Maps API but we will miss the built-in functionnalities of dvt:map
Thanks in advance,

Any news about this theme?

May be I'm too foolish to follow those links, I got issues of each links.
What I really want is an example from step0
Swarup:
Refer the Lookup document - Easy Lookup in Process Integration 7.1
https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/20befc9a-aa72-2b10-ae9b-b0988791d457
The first step is "Create an RFC Enabled Function Module for look up", but where can I create the function module? Should I use ESB, IB? or use transaction 'SE11' ?
Kulkarni:
Very good links for RFC lookup with 7.0/3.0

At page6 "PI Development/Configuration", it saies "You are on the design maintenance screen in the Integration Builder.Expand the subnodes for the software component version for which you want to import interfaces".
What is "design maintenance screen" ? My IB version is: Service Pack:08 Release:NW07_08_REL.
When I open IB, it display a screen titled with "Configuration: Intergation Builder", I did not find "software component version" node on the left tree.

The Prerequisites state:
The JDBC channel to be used for the lookup must be configured and activated in the Integration Directory.
The definition of the table used for the lookup must already be imported into the ES Repository as an external definition
But I don't know how to create a JDBC channel and define the table.

Hi Juan,
Are you trying to click on a point in the map and update another control on the page?
This is available today, if you create a master-detail binding and bind the master to your map theme, and detail to another view e.g. a table, and check the checkbox "Enable row selection" when you create the map theme binding, then you will get this behavior automatically.
If this is not what you are looking for, please clarify.

Use dvt map component into adf mobile

Hello,
I'm just wondering if it's possible to use the dvt map component into an adf mobile application or if there's another way to display a map coming from mapviewer.
Does anybody know it there are any limitations?
Thanks and regards

Currently DVT Map component is not supported for ADF Mobile. Alternatively you could look at embedding Google Maps or just invoke Google Maps from your app. On iOS and Android, if you create a link with something like ("http://maps.google.com/maps?q=<Text or EL Expression containing the value of the address you want to search>"), then native Google Maps application would be launched to display that address. You can also embed a Google Map in your page as an image as well - check Google Map's site for details of how to issue an URL that could return an image containing Google Maps and search results.
Thanks,
Joe Huang

DVT:MAP Component

Hi,
I have the following requirement, which i'm trying to implement with <dvt:map & <dvt:PointTheme components.
*The requirement is ... I have a base map, which is being accessed via <dvt:map component. And i'm using point theme to display certain data over the map. Let us consider, over the US map ... i'm displaying 24 points(for each polygonone point .... taking the centroid of each polygon) when the map zoom level is 0.
At this zoom level '0', user can see all 24 points. But when the user start clicking on '+' to Zoom In(Now the zoom level is '1'), at this zoom level user can see only 18 points. User can see the remaining 6 points by dragging the base map to either sides.
This mean, irrespctive of the zoom level the point theme is rendering the all the points over the map. Instead, i would like to display the data specific to the polygons that are visible to the user. At zoom level '0', if the user is able to see all the polygons, then display all 24 points. And at zoom level '1'...if the user is able to see 18 polygons and then display only those 18 points. And if the user tries to see the other polygons data ... user may drag the base map either sides. In that case, the point theme should render data specific to the polygons that the user is able to see.
Similarly, if the user is at zoom level '2'...at this zoom level user is able to see 13 polygons over the IE. so the point theme should render only 13 points specific to each polygon. If the user tries to do dragging the base map either sides...then display the points, specific to the polygons that the user is able to see.
Similarly for other zoom levels ... Please let me know if you require any other information.
Thanks & Regards,
Kiran Konjeti

Understanding point theme of dvt:map component

for usage of point theme..we have to mention either latitude and longititude or address and city and country and postal code
i want to know exactly what is latitude and longitude (these values varies if you use google maps and oracle maps ) and
in my data source i am also having x-cor ,y-cor ,longitude, latitude in every row
when using point theme.if i select X & Y(longitude & latitude).. is it sufficient to give latitude and longtitude..then purpose of x and y co-ordinates in data source...

s possible to obtain any example about how to use programatically a dvt.map component to send ( for example) a Zoom-In command to mapviewer server?

ADF Faces: dvt:map undefined title in the maptip

Hi! I'm using the component dvt:map that for specific reasons of my application I am inserting it on a page for a backing bean. When the map appears on the page and I click in a geometry of the current theme shows a map tip with information about the geometry but the title of map tip is writing as undefined. The theme of the map I inserting as PredefinedThemeFOI class. Do I must set some attribute in the map or PredefinedThemeFOI?
Edited by: reginaldo oliveira on 08/03/2011 12:35

If you are using predefined theme, please make sure you have a label column defined for your theme in mapBuilder. The label defined in the theme definition will be used as the header of the infoWindow.
