Help with Refreshing and Calling Screens

Hi everyone. I have somewhat of a simple ABAP program in which the user will enter data on Selection-Screen 1000. This will then be loaded into an Object Oriented ALV Grid for display purposes only (screen 0100). At any time, the user may use the back button on the ALV Grid Screen; which will take them from screen 0100 to screen 1000(Selection Screen). Lets assume the user does not want to go back to the original selection screen from the ALV Grid Screen; they entered the information correctly and want to continue processing using a custom button I've created which will continue to process the record of data into a BW ODS. This process works, but now I would like to use the write statement once the custom button is clicked to show a summary of the data I am inserting into the ODS after the data has been inserted. The problem is, the title of the ALV Grid still shows and the Write statement is processed, but not shown on the screen. I've been trying to refresh the screen with set screen and call screen combinations, but no luck. Any Help would be appreciated. Thanks!

There are some problems with ok_code, you need to assign sy-ucomm at each module. Also the main problem was that you needed leave to list-processing and suppress dialog before writing. However, when you do this the screens calls change a little. You also needed to use the container correctly. Apply the correctons below and you'll be all set. Unfortunaley you will have to play around with calling the sel. screen (1000) from screen 100, I don't think call sel. screen 1000 will work properly there (you might need a custome screen instead). The user may be okay with kicking back out to sa38 after the alv display, however. Good luck and don't listen to the clowns' comments above. I once worked in that circus, Hey Guys.

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.

... which gives me same rows with different head_counts.If they have different head_counts, then the rows are not the same.
I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

Help with volume and screen rotation.

Having trouble with volume and rotation. I have gone through the setting and made changes to lock screen and mute, but now it seems I have to choose between the two. The switch on the side also is not working. Any suggestions?

1. If Side Switch is set to Mute, check to make sure it's not muted
http://i1224.photobucket.com/albums/ee374/Diavonex/1237fb40.jpg
2. Check the Volume buttons

Help with moving between custom screens in a Standard Transaction

All,
I'm working with a standard transaction, but in this transaction, the I'm having 2 tabs of customized screens. In each of the screen, I have 1 mandatory fields to be filled. If the user only fill in the mandatory field of the first screen and click save, I need to display an error message and also display the second screen automatically? How can I do this? I tried to use CALL SCREEN 9200 but the system keep displaying the error "Screen SAPLXQQM 9200 must not be in Include screen".
Can anyone help me on this one? Thanks in advance.

You must don't calling screen 9200. I mean delete lines code
CALL SCREEN 9200.
from your program.
This code can be placement in screen fiew logic only!
Instead, set code of needed tab of tabstrip using FM. Program process this command and automaticly call tab with your 9200-subscreen.

Help with refreshing applet

If I recompile my applet and try to restart it in Netscape the changes do not take hold. I've tried refreshing and emptying the cache and even setting the cache to 0, but it won't run the new version of the program. The only way I can get it to work is to quit Netscape entirely, restart it, and start the Java program again. Why is this? And is there a way to get around this?
And there is a a second related problem I have. My applet calls a CGI program and recieves html text in reply. This HTML text I display in a JEditorPane. The first time I run the program it displays it nicely, but everytime after that it displays the HTML commands mixed in with the text, i.e. "<TABLE><TR><TD>text" instead of a table.
Does anyone know what causes this or how to prevent it?

Thanks for the help again. I read the API myself and tried adding the new line, but it had no affect. I tried this:
ResultsDisplay.getEditorKit().createDefaultDocument();
ResultsDisplay.setContentType("text/html");
ResultsDisplay.setText(inputStore.toString());and even this:
ResultsDisplay = new javax.swing.JEditorPane();
ResultsDisplay.getEditorKit().createDefaultDocument();
ResultsDisplay.setContentType("text/html");
ResultsDisplay.setText(inputStore.toString());But neither solution fixed it.

Help with icon on n85 screen

Hi all.
Looking for help with an icon that appears at near the top left corner of my n85 screen (I'm new to S60's). It appears when I'm either in a call using the keypad to dial a number. Sometimes it's a small arrow/triangle in an orange/red background and other times it's a green background.
Does this have anything to do with call diverts?? Tried googling and the forums but can't find anything.
Thanks everyone.
J.

kali,
that will come up to show you when you have something Java running. To close out of that once it is open, is to close out of all of your browser (IE for example) windows to reset the Java runtime environment.

Help with encapsulation and a specific case of design

Hello all. I have been playing with Java (my first real language and first OOP language) for a couple months now. Right now I am trying to write my first real application, but I want to design it right and I am smashing my head against the wall with my data structure, specifically with encapsulation.
I go into detail about my app below, but it gets long so for those who don't want to read that far, let me just put these two questions up front:
1) How do principles of encapsulation change when members are complex objects rather than primitives? If the member objects themselves have only primitive members and show good encapsulation, does it make sense to pass a reference to them? Or does good encapsulation demand that I deep-clone all the way to the bottom of my data structure and pass only cloned objects through my top level accessors? Does the analysis change when the structure gets three or four levels deep? Don't DOM structures built of walkable nodes violate basic principles of encapsulation?
2) "Encapsulation" is sometimes used to mean no public members, othertimes to mean no public members AND no setter methods. The reasons for the first are obvious, but why go to the extreme of the latter? More importantly HOW do you go to the extreme of the latter? Would an "updatePrices" method that updates encapsulated member prices based on calculations, taking a single argument of say the time of year be considered a "setter" method that violates the stricter vision of encapsulation?
Even help with just those two questions would be great. For the masochistic, on to my app... The present code is at
http://www.immortalcoil.org/drake/Code.zip
The most basic form of the application is statistics driven flash card software for Japanese Kanji (Chinese characters). For those who do not know, these are ideographic characters that represent concepts rather than sounds. There are a few thousand. In abstract terms, my data structure needs to represent the following.
- There are a bunch of kanji.
   Each kanji is defined by:
   - a single character (the kanji itself); and
   - multiple readings which fall into two categories of "on" and "kun".
      Each reading is defined by:
      - A string of hiragana or katakana (Japanese phoenetic characters); and
      - Statistics that I keep to represent knowledge of that reading/kanji pair.Ideally the structure should be extensible. Later I might want to add statistics associated with the character itself rather than individual readings, for example. Right now I am thinking of building a data structure like so:
- A Vector that holds:
   - custom KanjiEntry objects that each hold
      - a kanji in a primitive char value; and
      - two (on, kun) arrays or Vectors of custom Reading objects that hold
         - the reading in a String; and
         - statistics of some sort, probably in primitive valuesFirst of all, is this approach sensible in the rough outlines?
Now, I need to be able to do the obvious things... save to and load from file, generate tables and views, and edit values. The quesiton of editting values raises the questions I identified above as (1) and (2). Say I want to pull up a reading, quiz the user on it, and update its statistics based on whether the user got it right or wrong. I could do all this through the KanjiEntry object with a setter method that takes a zillion arguments like:
theKanjiEntry.setStatistic(
"on",   // which set of readings
2,      // which element in that array or Vector
"score", // which statistic
98);      // the valueOr I could pass a clone of the Reading object out, work with that, then tell the KanjiEntry to replace the original with my modified clone.
My instincts balk at the first approach, and a little at the second. Doesn't it make more sense to work with a reference to the Reading object? Or is that bad encapsulation?
A second point. When running flash cards, I do not care about the subtlties of the structure, like whether a reading is an on or a kun (although this is important when browsing a table representing the entire structure). All I really care about is kanij/reading pairings. And I should be able to quickly poll the Reading objects to see which ones need quizzing the most, based on their statistics. I was thinking of making a nice neat Hashtable with the keys being the kanji characters in Strings (not the KanjiEntry objects) and the values being the Reading objects. The result would be two indeces to the Reading objects... the basic structure and my ad hoc hashtable for runninq quizzes. Then I would just make sure that they stay in sync in terms of the higher level structure (like if a whole new KanjiEntry got added). Is this bad form, or even downright dangerous?
Apart from good form, the other consideration bouncing around in my head is that if I get all crazy with deep cloning and filling the bottom level guys with instance methods then this puppy is going to get bloated or lag when there are several thousand kanji in memory at once.
Any help would be appreciated.

Usually by better design. Move methods that use the
getters inside the class that actually has the data....
As a basic rule of thumb:
The one who has the data is the one using it. If
another class needs that data, wonder what for and
consider moving that operation away from that class.
Or move from pull to push: instead of A getting
something from B, have B give it to A as a method
call argument.Thanks for the response. I think I see what you are saying.. in my case it is something like this.
Solution 1 (disfavored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          char theKanji = currentKanjiEntry.getKanji();
          String theReading = currentKanjiEntry.getReading();
          // build and show a flashcard based on theKanji and theReading
          // use a setter to change currentKanji's data based on whether the user answers correctly;
}Solution 2 (favored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          currentKanji.buildAndShowFlashcard(); // method includes updating stats
}I can definitely see the advantages to this, but two potential reasons to think hard about it occur to me right away. First, if this process is carried out to a sufficient extreme the objects that hold my data end up sucking in all the functionality of my program and my objects stop resembling natural concepts.
In your shopping example, say you want to generate price tags for the items. The price tags can be generated with ONLY the raw price, because we do not want the VAT on them. They are simple GIF graphics that have the price printed on a an irregular polygon. Should all that graphics generating code really go into the item objects, or should we just get the price out of the object with a simple getter method and then make the tags?
My second concern is that the more instance methods I put into my bottom level data objects the bigger they get, and I intend to have thousands of these things in memory. Is there a balance to strike at some point?
It's not really a setter. Outsiders are not setting
the items price - it's rather updating its own price
given an argument. This is exactly how it should be,
see my above point. A breach of encapsulation would
be: another object gets the item price, re-calculates
it using a date it knows, and sets the price again.
You can see yourself that pushing the date into the
item's method is much beter than breaching
encapsulation and getting and setting the price.So the point is not "don't allow access to the members" (which after all you are still doing, albeit less directly) so much as "make sure that any functionality implicated in working with the members is handled within the object," right? Take your shopping example. Say we live in a country where there is no VAT and the app will never be used internationally. Then we would resort to a simple setter/getter scheme, right? Or is the answer that if the object really is pure data are almost so, then it should be turned into a standard java.util collection instead of a custom class?
Thanks for the help.

ALV not getting refreshed when call screen is executed second time

I have 2 screens 9001 and 9002. In 9001 , I am displaying the fields of a database table in a Table Control. The user has to select some of those fields and click on a button 'Generate ALV'. After clicking , the control navigates to 9002 where I am displaying ALV with data in the selected fields(the other fields remain empty). (using custom container)
Now there is BACK button in 9002 where i have written LEAVE TO SCREEN 9001. After this if the user again make changes in column selection and click on 'Generate ALV' , then still the old alv data is displayed. (Mind you the structure of alv is same , only the selected fields should show data).
I am using REFRESH_ALV_DISPLAY also and when i tested this function independently , its working fine (although for interactive alv in the same screen).
I am making use of <fs> for dynamic internal table and i checked it using breakpoints , during the 2nd time , it contains the correctly updated data so i think the problem lies with alv
Kindly check this code
MODULE STATUS_9002 OUTPUT.
SET PF-STATUS 'ZALV'.

CREATE OBJECT C_CONT
 EXPORTING
 CONTAINER_NAME = 'CUST_CONT'
IF SY-SUBRC <> 0.

Altough it's not a really nice solution... Why using 2 screens for example? you could use two containers instead...
Also I would recommand playing with the new salv class for your grids.
Anyway don't hesitate to give feed-back.

Help with Facebook and Social Media wigets (Was: How do I fix the three probs that...)

I am having problems with the facebook or social media widgets. I would like the link to send viewers to my facebook business page, but when testing it shows my pic and a 'switch' sign (see screen shot) and when I open the site the message is as the other screenshot, great, but I don't know where to find which 'asset' is the problem and why. Also why bother having child pages if the menu doesn't reflect that? I see that drop down menus are an issue, also with some other forum members.
Thanks for any help offered!, I think I have solved the first problem now but still would appreciate any help with the other 2!
For some reason the facebook widget now loads the correct page, and I give up about the drop down menu, hopefully this will be addressed in the next update of Muse??

Hello,
For the "asset" issue, try locating the asset in the assets panel. It should have an icon like this: http://jingsite.businesscatalyst.com/jing/2013-12-16_0917.png
For the child pages in the menus issue, go to the menu options (by clicking the small blue arrow in the right top corner of the menu), and then change the menu type to "All Pages" instead of "Top Level Pages".
Hope this helps.
Cheers

Help with WindowsDesktopSSO and AMIdentity.getAttributes

Hi guys and girls,
I need some help from you experts.
I successfully setup, thanks to this guide
http://blogs.oracle.com/knittel/entry/opensso_windowsdesktopsso
and a lot of trial & errors and googling a Kerberos authentication between OpenAM version 9.5.2 and an Active Directory Server.
When I navigate to openAM page (from a domain machine) http://<openAMhost>:<port>/opensso, it doesn't ask for credentials ...
and I can see, with ieHttpHeaders, kerberos data exchange.
Without creating an Active Directory DataStore (pointing to the same domain where I use kerberos data) in openAM,
when I navigate (from a domain machine) to /opensso/idm/EndUser page, it always gives me:
"Plug-in com.sun.identity.idm.plugins.ldapv3.LDAPv3Repo encountered an ldap exception. LDAP Error 32: The entry specified in the request does not exist."
Since my aim was to get user information from a web app ... I thought I could have done this with an agent/SDK call as I usually do with "classic" authentication.
Now I created a J2EE Agent (on openAM) to protect one of my application deployed on a JBoss 4.2.1-GA server.
Agent configured with default options and these changes:
Agent Filter Mode: J2EE_POLICY
User Mapping Mode: USER_ID
User Attribute Name: tried both with employeenumber and uid
User Principal Flag: enabled
User Token Name: UserToken
FQDN Check: tried both with enabled and disabled
WebAuthentication Available : Enabled
In my application WEB-INF/jboss-web.xml looks like this:
 <?xml version="1.0" encoding="UTF-8"?>
 <jboss-web>
 <security-domain>java:/jaas/AMRealm</security-domain>
 </jboss-web>Usually, when I authenticate with "classic" (internal datastore) login, I can get user attributes programmatically with a code like this:
 private String getCredenzialiUtente(HttpServletRequest request)
 String SSOUsername = null;
 SSOToken ssoToken = null;
 SSOTokenManager manager = null;
 try
 manager = SSOTokenManager.getInstance();
 if ( manager == null)
 throw new RuntimeException("Unable to Get: SSOTokenManager");
 String ssoTokenID = AmFilterManager.getAmSSOCache().getSSOTokenForUser(request);
 ssoToken = manager.createSSOToken(ssoTokenID);
 if ( ssoToken == null )
 throw new RuntimeException("Unable to Get: TokenForUser");
 AMIdentity amid = new AMIdentity(ssoToken);
 if(amid == null)
 throw new RuntimeException("Unable to Get: UserIdentity");
 SSOUsername = amid.getName();
 System.out.println("######### USERNAME FROM SSO: " + SSOUsername);
 Set<String> info = new HashSet<String>();
 info.add("uid");
 info.add("givenName");
 java.util.Map mappa = amid.getAttributes(info);
 if ( mappa != null )
 java.util.Set insieme = mappa.keySet();
 java.util.Iterator it = insieme.iterator();
 while ( it.hasNext() )
 String n = it.next().toString();
 System.out.println( n + " ==> " + mappa.get(n) );
 else
 System.err.println(" DAMN - NO ATTR ");
 catch (Exception exception)
 exception.getMessage();
 exception.printStackTrace();
 System.out.println("OUT getCredenzialiUtente: " + SSOUsername);
 return SSOUsername;
 } When I log to console with default "ldapService" module (outside the domain), I can get something like:

 2011-09-29 13:15:39,877 INFO [STDOUT] OUT getCredenziali: tonywebAs you can see I'm using the "sample" agentApp.war.
What am I missing ? It "crashes" as for getAttributes() call :/
I thought it could be because I didn't setup LDAP DataStore ... so I set up Active Directory Data Store.
While in openAM console (from outside domain) I can see (from Subjects tab) Active Directory users and relative information
(like FirstName (=givenName), Surname (=sn), Full Name (=cn), etc.) ... when I try again with idm/EndUser (from a domain machine)
I get the same error:
 Message:Plug-in encountered an ldap exception. LDAP Error 32: The entry specified in the request does not exist.What should I do now ?
If you need more clarifications ... just ask :)
Thank you in advance and sorry for the big post.
Best Regards,
Tony
P.D. By the way, my OpenAM configuration does not create any "amAuthWindowsDesktopSSO.log" :(
I setup, from opensso/Debug.jsp message level for Authentication ... but it still doesn't create this log ... can you please tell me how to let openAM write it ?
Again thank you

Weird enough, changing to ADAM data store (and not "standard" AD datastore) solved the problem :D
I still wonder why since both plugins share the same java [implementing] class...

Tony

Problem with ALV_GRID and CALL TRANSACTION.

Hi all, Could you please tell me
At SE38
Why REUSE_ALV_GRID_DISPLAY and CALL TRANSACTION after called then I click the back button to return to the calling program but it automatic return to the source code? (it hasn't saves the data in alv grid )
In another case of this program, after automatic return to the source code then I have to waiting for 5-10 mins for execute again cuz if immediately execute the program don't fill any data to the alv grid.
I have problem with a simple source code like this
REPORT ZFS_ALV_DEMO.

Using Search Help with ALV and Dynamic context node

The topic subject already describes my situation.
I have to create, populate and remove context nodes at runtime, and bind them to an ALV, to let user display the data or modify the data. The nodes I create are always typed with a table name, but the table name is of course, dynamic.
This is all working: what's not working is help for entries inside the ALV; since the table has foreign keys and domains with check tables or fixed values, I expected that search helps were detected and managed by the framework.
Instead, no help search is displayed except the input help based on data-type of the one "Date" input fields.
I think I have to work on the dynamic node creation, and not on the ALV itself, since the latter only takes the node/attributes information, but i could be wrong. I tried with both the two following codings:
CALL METHOD lo_nd_info_root->add_new_child_node
    EXPORTING
      static_element_type          = vs_tabname
      name                         = 'SAMPLE_NODE_NAME'
*    is_mandatory                 = abap_false
*    is_mandatory_selection       = abap_false
     is_multiple                  = abap_true
     is_multiple_selection        = abap_false
*    is_singleton                 = abap_false
      is_initialize_lead_selection = abap_false
      is_static                    = abap_false
    RECEIVING
      child_node_info              = lo_nd_info_data .
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
      parent_info = lo_nd_info_root
      node_name = 'SAMPLE_NODE_NAME'
      structure_name = vs_tabname
      is_multiple = abap_true ).
The result is the same...is there any way to let the ALV know what search helps it has to use, and doesn't force me to manually build a VALUE_SET to be bound on the single attributes? There are many tables, with many fields, and maintaining this solution would be very costly.

I have checked with method GET_ATTRIBUTE_VALUEHELP_TYPE of interface IF_WD_CONTEXT_NODE_INFO, on an attribute which i know to have a search help (Foreign key of a check table).
The method returns 'N', that is the constant IF_WD_VALUE_HELP_HANDLER~CO_VH_TYPE_NO_HELP. So, the framework was not able to find a suitable search help.
Using method GET_ATTRIBUTE_VALUE_HELP of the same interface, on the same attribute, returns me '111', which is constant C_VALUE_HELP_MODE-AUTOMATIC.
Therefore, the WD framework knows it has to automatically detect a value help, but fails to find one.
Also, this means in my opinion that the ALV and the dynamic external mapping are not the culprits: since node creation, no help is detected for any attribute but the date. Honestly, I don't have a clue on what's happening.
