Changing FieldCatalog at runtime in an ALv

Hi All,
I have a requirement like : On selection-screen I have 2 input parameters and 2 pushbuttons namely. After input, if press one of these pushbuttons a pop up will come which is having 2 radio buttons. Based on the selection of the radiobutton, I need to make some of the fields editable in a fieldcatalog. But what my problem is .... whatever I select[Radio Button] the first time only that fieldcatalog is getting displayed. Hope I am clear in explaining my problem.

I don't understand this either, I've tried replacing "PaintOff(1)" with "vOn()" but I get the same error. This is baffling to be, as I thought that the hour11 would have access to all the methods inside the PaintOff class?
Anyway, thanks for any help you guys give me!
Cheers
//Chris.

Hi!
Your problem is that you've used a widening conversion to convert from PaintOff to a JPanel. JPanel has no such method, and so the compiler is complaining that it can't find it.
e.g
public class NoCompile{
     public static void main(String args[]){
          One one = new Two();
          one.methTwo();
public class Two extends One{
     public Two(){}
     public void methTwo(){
        System.out.println("Executed 2");
public class One{
     public One(){}
     public void meth1(){}
} will give you the same sort of error message. To make the compiler happy, use a cast.
Now this will compile and gives the right result.
public class NoCompile{
     public static void main(String args[]){
          One one = new Two();
          ((Two)one).methTwo();
}So in your case, you want to do
((PaintOff)hour11).vOn();
Does that help?

How to include change delete and insert options in alv grid display

Hi,
As per my requirement I need to display my output in grid.
When the user makes any changes to any field of the alv it should get reflected in the tatabase table.
Similarly according to the requirement if user enters a new coloumn to the alv or deletes one or more rows of the alv,same should be reflected in the databse table.
I know there are many methods in object oriented.
But its little bit tough for me to implement..
Please suggest how to code for it without oo concepts.
Thanks ,
Smriti

Hi,
use FM with Edit functionality enabled for all fields and
Create one pf-status with some buttons
if user presses the button the alv output table should be saved and same table can be used to insert /modify /delete the dbtable.

Changing picture at runtime using delphi

Post Author: iman_400
CA Forum: Other
Please help me, is there anyway we can change picture at runtime using delphi 7.0 and CRXIR2?

Hi, Lee;
For the version of Crystal Reports that comes with .NET, you can use something like one of our samples shows:
https://smpdl.sap-ag.de/~sapidp/012002523100006252822008E/net_win_smpl.exe
Look for the sample, vbnet_win_DynamicImage.zip. It uses an ADO.NET dataset to change the image.
For Crystal Reports XI R2 and Crystal Reports 2008, you can more directly change the image location using built in functionality.
In the Designer, choose Insert > Picture. Choose a default image to show and save it. Right-click on it and select Format Graphic. Go to the Picture tab and click the formula button for Graphic location. Save the report.
Then, at runtime you can populate the Formula with the new location for your image, either a URL or disk file location.
See the following note for more information:

Change to the runtime the logon language with ABAP

Hello,
I have a question.
Is it possible to change to the runtime the logon language?
With the URL-parameter example it worked.
http://www.****bsp/sap/z_page/default.htm?sap-language=en
But I need this in the event handler with ABAP coding.
thanks Eren

you can either use
CL_HTTP_UTILITY->IF_HTTP_UTILITY~SET_REQUEST_URI
uri = sap-language=FR
or
CL_HTTP_REQUEST->IF_HTTP_ENTITY~SET_FORM_FIELD
name = sap-client
value = FR
or
use
SET LOCALE LANGUAGE 'S'. within your abap coding

[svn] 3839: Update the channel url to reflect the change in the runtime channel

Many ways to do this. The easiest is to have a method in one of your classes that reads the data from the database and creates all the proper structure under a RootNode and then returns that RootNode.
Whenever you want to refresh the tree, just call that method to recreate the root node (and all the underlying structure/nodes) and then re-set the root node of your tree model using the setRoot() method. That will cause it to refresh the display given the new root node.
Once you have that working, you can get fancier and make it more efficient (only updating/firing events for the nodes that actually changed, etc).

To change table data runtime when dropdown item is changed

Hi,
I have two ui elements(Dropdown by index and table) in single view .
I need to display table as per drondown index item selection. Means i have to change table data runtime when dropdown item is changed.Please help me in that .Please provide code for same.
Regards,
gurprit Bhatia

Hello gurprit Bhatia,
On the view create a new action. Fill only the Name and Text and leave the other items default.
In this event you can populate the table fields.
Bound this newly created action (event) to the onSelect property of the 'DropDownByIndex'.

How to change the standard layout sets in ALV List

Hi Gurus,
How to change the standard layout sets in ALV list.
Is there any standard program ? or specific way to acheive this?
Kindly drop some clues?Every valuable clues rewarded more points........
Thanks in Advance,
Dharani

Hello Dharani
All required function modules can be found in function group SLVC (assuming that you are using OO-based ALV or, at least, fm REUSE_ALV_GRID_DISPLAY_LVC):
LVC_VARIANT_DEFAULT_GET (Read default display variant (description only, w/o field catalog))
LVC_VARIANT_EXISTENCE_CHECK
LVC_VARIANT_F4 (Display variant selection dialog box)
LVC_VARIANT_SELECT (Read a display variant)
For a sample report using LVC_VARIANT_DEFAULT_GET have a look at BCALV_GRID_10.

Uwe

Runtime Error in ALV Tree Output

Dear All, I am trying to create a ALV Tree using Class cl_gui_alv_tree. The Report Shows the Output with the first Node but when i try to expand it is dumping with a runtime error GETWA_NOT_ASSIGNED in class CL_ALV_TREE_BASE and method SET_ITEMS_FOR_COLUMN. The Reason being the data which was copied in the initial node display to mt_outtab is getting refreshed.
Can any one of you help me the reason for the table getting refreshed. Do i need to pass any data.
I am doing the following steps.
1. Create Container,
2. Create Tree Class object
3. Generate the Field Catalog.
4. Set table for first display " With empty internal table
5. Generate the Hierarchy
6. Call the Method Frontend Update.
Let me know if i had missed any steps in the process.
Thank you,
Regards,
Swaroop Patri

One reason for getting this error is using local defined tables for it_outtab parameter in the below code:
To get rid of the dump, define two distinct output tables globally: one is an empty table which you will pass to the below method, other one is your real output table whose size increases dependently.
CALL METHOD go_tree->set_table_for_first_display
      EXPORTING
        is_hierarchy_header = ls_hier_header
      CHANGING
        it_outtab           = gt_data_e "Empty table
        it_fieldcatalog     = gt_fcat_tree.

How to change header value dynamiclly in procedural alv report?

Hi experts,
I develop one report (using procedural alv ).I gave 3 input check boxes (ex : in 1st checkbox 10days in 2nd check box 20 days
in 3rd check box 30 days they entered like this in the input checkboxes in days 10,20,30.In o/p report 3 columns i maintained like this .   Column1                          column2                                                 column 3
       from 0 to 10 days          from 11 to 20 days                                    from 21 to 30 days.
I want to display alv report o/p like this in the respective columns.
For example they enter 15 25 35 (i/p)
o//p in alv report
   Column1                          column2                                                 column 3
       from 0 to 15 days          from 16 to 25 days                                    from 26 to 35 days.
i want to change days dynamically in alv header .Pls give me the code using procedural alv report.
If u want i will give u detail.pls help me in this.

I assume the main issue is chaniging ALV header dynamically, isn't it? For this you need to use field seltext_m of fieldcatalog for particular column. So you can contruct header dynamically by string concatenation like
parameters: pa_1st(2) type n, "i.e. 15
                    pa_2nd(2) type n, "i.e 25
                    pa_3rd(2) type n. "i.e. 35
"first field
concatenate '0' 'to' pa_1st into it_fieldcatalog-seltext_m.
"next field
add 1 to pa_1st.
concatenate pa_1st 'to' pa_2nd into it_fieldcatalog-seltext_m.
"last field
add 1 to pa_2nd.
concatenate pa_2nd 'to' pa_3rd into it_fieldcatalog-seltext_m.

There are a number of ways to create a fieldcat.
For the purpose of this example i will build the fieldcatalog manualy
by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.
Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
              I.e. Field type may be required in-order for
                   the 'TOTAL' function to work.
