BDC on transaction CV02N handling the Custom Control

Hi Guru's,
I am developing a BDC program for the transaction CV02N. This transaction is for Changing the document link. Here I need to delete the existing Document links and create the new ones.
I am facing the issue for Deleting the document links. The custom control has the links for each document. I need to select each document link in the custom control then delete it. But the BDC recording is not showing this selection of document links in the custom control, If I write the program using the recording, it is stopping me at the time of pressing the delete button, and giving the message make the selection.
I dont know how to handle this custom control's in BDC program. Please help me.
Thanks
Ravi.

Use the [search tool for CV02NBDC|http://www.sdn.sap.com/irj/scn/advancedsearch?query=cv02nBDC] and then [for CV02NBAPI|http://www.sdn.sap.com/irj/scn/advancedsearch?query=cv02nBAPI] (look for BAPI_DOCUMENT*)
Basically, transaction ending with "N" are Enjoy, and not fully suitable for BDC, so look for BAPI, or sometimes for older version of the transaction, without the trailing "N" (til they become obsolete)

Raymond

BAPI is not going through the screen flow logic so you need not to worry about the table control. Just check in the BAPi there must be one table parameter for line items just pass one int table with your data to that table parameter it will automatically update the tables.

ALV Display on the Custom Control

Hi Friends,
Iam developing a Module Pool program where I call a ALV grid on a custom control.
I have only one screen in which i have a input field and a custom control.
when I enter a material number in the input field and press ENTER the custom control should be populated with some of the material details. I have written all the logic. But the problem is when i press enter the custom control is not filled but after I press the REFRESH button present by default on the grid, the details are displayed.
What is the problem??
Regards,
Raju...

HI,
Use the method REFRESH_TABLE_DISPLAY after filling the new values into it_outtab table. in the PBO flow logic of your Module pool program.
CALL METHOD grid1->refresh_table_display.

Hide the custom control while changing the tab

Hello Experts,
I am using many screens & subscreens in my application. In a tabstrip control, I am calling one subscreen which has Custom Control to display the text editor.
When I change the tab say for ex from TAB1 to TAB2, the custom control with text editor remains at the same place. In TAB2 I dont want custom control of TAB1.
Thank you to go through my query.
Regards,
Bhavina

Hello Alej,
I have created one subscreen which i need in a tabstrip control. Now this subscreen has one Editor Control (CL_GUI_TEXTEDIT->TEXT_EDITOR) which I put on Custom Control. Custom Control is placed in the subscreen with SE51.
to put the editor control of CL_GUI_TEXTEDIT, I need Custom Control on screen. And I didnt find any property using which we can hide custom control.
Is there any way using classes or methods, can we put Editor Control without using the custom control of screen.
I think in your prob, you had ALV, that we can put on another subscreen, but in my prob how can we remove custom control Please Explain.
Thanks & Regards,
Bhavina

How to handle the table control While working with LSMW?

How to handle the table control While working with LSMW?

its possible in lsmw,
Hi,
LSMW will have a Indicator for headr and itam, i do not remember the correct field, but it will have an indicator, check the fields, there will be a single charecter lenght field, that should be the indicator, and using that we can write the logic.
check that single charecter field, it that is X that means the header record is processed, and do the items.
and, this is another way, try this out also
YOu can do this in "Define Source Structures" step,
the HEADER is defined first,
then the DETAIL below the HEADER.
add the fields to the structures.
Both should have some common key field
Please take care that the name of the common field is the same.
Once you do this it is linked. The you have a header and item corresponding to that header. then run the LSMW as you would.
Thanks

How to use the custom control ?

Hi Friends,
plz help to use of custom control in screen painter ?
and how to use the custom control ?
Thanking you.
Regards,
Subash.

HI,
Screen Elements
A screen can contain a wide variety of elements, either for displaying field contents, or for allowing the user to interact with the program (for example, filling out input fields or choosing pushbutton functions). You use the Screen Painter to arrange elements on the screen.
You can use the following elements:
·        Text fields
Display elements, which cannot be changed either by the user or by the ABAP program.
·        Input/output fields and templates
Used to display data from the ABAP program or for entering data on the screen. Linked to screen fields.
·        Dropdown list boxes
Special input/output fields that allow users to choose one entry from a fixed list of possible entries.
·        Checkbox elements
Special input/output fields that the user can either select (value X) or deselect (value SPACE). Checkbox elements can be linked with function codes.
·        Radio button elements
Special input/output fields that are combined into groups. Within a radio button group, only a single button can be selected at any one time. When the user selects one button, all of the others are automatically deselected. Radio button elements can be linked with function codes.
·        Pushbuttons
Elements on the screen that trigger the PAI event of the screen flow logic when chosen by the user. There is a function code attached to each pushbutton, which is passed to the ABAP program when it is chosen.
·        Frame
Pure display elements that group together elements on the screen, such as radio button groups.
·        Subscreens
Area on the screen in which you can place another screen.
·        Table controls
Tabular input/output fields.
·        Tabstrip controls
Areas on the screen in which you can switch between various pages.
·        Custom Controls
Areas on the screen in which you can display controls. Controls are software components of the presentation server.
·        Status icons
Display elements, indicating the status of the application program.
·        OK field
Every screen has a twenty-character OK_CODE field (also known as the function code field) that is not displayed directly on the screen. User actions that trigger the PAI event also place the corresponding function code into this field, from where it is passed to the ABAP program. You can also use the command field in the standard toolbar to enter the OK field. To be able to use the OK field, you need to assign a name to it.
All screen elements have a set of attributes, some of which are set automatically, others of which have to be specified in the Screen Painter. They determine things such as the layout of the screen elements on the screen. You can set the attributes of screen elements in the Screen Painter - either for a single element, or using the element list, which lists all of the elements belonging to the current screen. Some of the attributes that you set statically in the Screen Painter can be overwritten dynamically in the ABAP program.

How to limit the number of rows in the Custom Control box

Hi All,
In my Module pool screen I have a Custom Control box for providing some free text as input. Now, there is no limit in the number of rows allowed for this box.
But, the requirement is, it should have the maximum number of rows = 99. and each row should have maximum length = 60 characters.
User should not be allowed to enter more than 60 characters per row and more than 99 rows.
Could you please let me know how to do this..? Are there any methods available which controls the maximum number of rows and maximum length per row..?
Please help me in resolving the issue. Thanks in advance.
Thanks & Regards,
Paddu.

By "Custom Control Box", do you mean a Custom Container or a Table Control?
Anyway, I suggest you to use a table control (not a custom container as your requirement seems to be very precise on that point, maybe ask your client twice to make sure). Look at the examples of table controls in ABAPDOCU transaction.

BDC for transaction AC02, output the activity number on screen

HI,
how to get the system created activity number on to the output screen after completion of BDC, data transfer using call transaction.
with regards,
sagar.

Hi,
Do you want that once the BDC is finished then it should stay on same screen with activity number if yes you will get the activity number in your BDCMSG table. Using that you can set paramter id ASN and do a call transaction again.
Please let us know if your requirement is different from the above one.

Error calling a method of the tree control in BDC

I'm connecting two systems Iplan(project management tool) with SAP PS using SAP XI.
I've written an BDC(RFC) to assign people for the activity in an project(cj20n) it works fine in the foreground. But it doesn't work in the background.It doesn't give me error also.I've sap all authorization.
When I connect with XI its throwing me an error "Error calling a method of the tree control" message type A (using the same user to connect r3). I believe something we should do prior handling the tree control in a BDC. IF any body come across this situation please let me know. your help is appreciated.
Regards
Anand

BDCs over enjoy transactions do not get along together. The containers and controls is more of a gui thing, and in background sometimes the BDC has a hard time with them. I would suggest using the non-enjoy tcode instead, CJ20.

Dynpro: event handling on input field in custom control?

Hello,
can I put an input/output Field in Custom Control?
I have seen this (DD_ADD_FORM_INPUT) but i dont need a Form.
What i want to do is: Double Click Event handling on the input field in the custom control.
Thank you?

Hi Mohi,
OK, you could reduce DD_ADD_FORM_INPUT to what you really need - but the DD elements (rarely if ever used in standard SAP) do not have a double-click event. Must stick to ENTER.
An alternative is a text_edit or an editable grid_control with one line one field.
The problem is: There is no way to put any selection-screen element on a control.
I's go for the grid approach as you certainly may have some more fields of interest.
Regards,
Clemens.

How do I find the EventID of an event in a custom control?

Hi all,
I have a custom control created in VB .NET that I have embedded into a SAP screen using a wrapper class as described in Thomas Jungs example: <a href="/people/thomas.jung3/blog/2004/09/01/using-net-windows-controls-in-the-abap-control-framework .Net Windows Controls in the ABAP Control Framework</a>
My problem is that I cannot get the wrapper class to react to any events raised by the custom control!
I do not know how to find what the EventID is of an event so that I can register it in the class - do you know how to find this EventID? Or even if this is the problem?

Problem with custom control and focus

I've a problem with the focus in a custom control that contains a TextField and some custom nodes.
If i create a form with some of these custom controls i'm not able to navigate through these fields by using the TAB key.
I've implemented a KeyEvent listener on the custom control and was able to grab the focus and forward it to the embedded TextField by calling requestFocus() on the TextField but the problem is that the TextField won't get rid of the focus anymore. Means if i press TAB the first embedded TextField will get the focus, after pressing TAB again the embedded TextField in the next custom control will get the focus AND the former focused TextField still got the focus!?
So i'm not able to remove the focus from an embeded TextField.
Any idea how to do this ?

Here you go, it contains the control, skin and behavior of the custom control, the css file and a test file that shows the problem...
control:
import javafx.scene.control.Control;
import javafx.scene.control.TextField;
public class TestInput extends Control {
 private static final String DEFAULT_STYLE_CLASS = "test-input";
 private TextField textField;
 private int id;
 public TestInput(final int ID) {
 super();
 id = ID;
 textField = new TextField();
 init();
 private void init() {
 getStyleClass().add(DEFAULT_STYLE_CLASS);
 public TextField getTextField() {
 return textField;
 @Override protected String getUserAgentStylesheet() {
 return getClass().getResource("testinput.css").toExternalForm();
 @Override public String toString() {
 return "TestInput" + id + ": " + super.toString();
}skin:
import com.sun.javafx.scene.control.skin.SkinBase;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.EventHandler;
import javafx.scene.control.TextField;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
public class TestInputSkin extends SkinBase<TestInput, TestInputBehavior> {
 private TestInput control;
 private TextField textField;
 private boolean initialized;
 public TestInputSkin(final TestInput CONTROL) {
 super(CONTROL, new TestInputBehavior(CONTROL));
 control = CONTROL;
 textField = control.getTextField();
 initialized = false;
 init();
 private void init() {
 initialized = true;
 paint();
 public final void paint() {
 if (!initialized) {
 init();
 getChildren().clear();
 getChildren().addAll(textField);
 @Override public final TestInput getSkinnable() {
 return control;
 @Override public final void dispose() {
 control = null;
}behavior:
import com.sun.javafx.scene.control.behavior.BehaviorBase;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.EventHandler;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
public class TestInputBehavior extends BehaviorBase<TestInput> {
 private TestInput control;
 public TestInputBehavior(final TestInput CONTROL) {
 super(CONTROL);
 control = CONTROL;
 control.getTextField().addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() {
 @Override public void handle(final KeyEvent EVENT) {
 if (KeyEvent.KEY_PRESSED.equals(EVENT.getEventType())) {
 keyPressed(EVENT);
 control.focusedProperty().addListener(new ChangeListener<Boolean>() {
 @Override public void changed(ObservableValue<? extends Boolean> ov, Boolean wasFocused, Boolean isFocused) {
 if (isFocused) { isFocused(); } else { lostFocus(); }
 public void isFocused() {
 System.out.println(control.toString() + " got focus");
 control.getTextField().requestFocus();
 public void lostFocus() {
 System.out.println(control.toString() + " lost focus");
 public void keyPressed(KeyEvent EVENT) {
 if (KeyCode.TAB.equals(EVENT.getCode())) {
 control.getScene().getFocusOwner().requestFocus();
}the css file:
.test-input {
 -fx-skin: "TestInputSkin";
}and finally the test app:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
public class Test extends Application {
 TestInput input1;
 TestInput input2;
 TestInput input3;
 TextField input4;
 TextField input5;
 TextField input6;
 Scene scene;
 @Override public void start(final Stage STAGE) {
 setupStage(STAGE, setupScene());
 private Scene setupScene() {
 input1 = new TestInput(1);
 input2 = new TestInput(2);
 input3 = new TestInput(3);
 input4 = new TextField();
 input5 = new TextField();
 input6 = new TextField();
 GridPane pane = new GridPane();
 pane.add(input1, 1, 1);
 pane.add(input2, 1, 2);
 pane.add(input3, 1, 3);
 pane.add(input4, 2, 1);
 pane.add(input5, 2, 2);
 pane.add(input6, 2, 3);
 scene = new Scene(pane);
 return scene;
 private void setupStage(final Stage STAGE, final Scene SCENE) {
 STAGE.setTitle("Test");
 STAGE.setScene(SCENE);
 STAGE.show();
 public static void main(String[] args) {
 launch(args);
The test app shows three custom controls on the left column and three standard textfields on the right column. If you press TAB you will see what i mean...
