Problem with FM:DB_SELECT GENERIC TABLE in 6.0

Hi Experts,
There is one report, which is copyed from 4.6 to ECC 6.0. Now my problem is inside the report one FM: DB_SELECT GENERIC TABLE is called. This FM is working properly in 4.6. But it is not working in 6.0 I mean this FM is not fetching the data in 6.0 even though the records are exist in DB tables.
is there any alternative FM to use instead of above FM. or what might be the problem that FM is not fetching the re
Thanks in advance

Hi,
data: genkey(120) type c,
        genkeyl type i,
tabname type TABNAME.
refresh: itab.
Have a genkey1 validation
if genkeyl gt 0.
call the FM
    call function 'DB_SELECT_GENERIC_TABLE'
         exporting
              bypass      = 'N'
              genkey      = genkey
              genkey_ln   = genkeyl
              tablename   = tabname
         tables
              inttab      = itab
         exceptions
              db_error    = 01
              not_found   = 02
              wrong_param = 03.
try the above code and ensure that you are catching the exceptions .
try it and then get back to the forum.

Problems with retrieving data from tables with 240 and more records

Hi,
I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
So for the retrievals that hang I have something like:
(3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
(3260008): FETCH NEXT:(DBI_FETCHNEXT)
and this is the last line,
while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
I will appreciate any comments/hints/help.
Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.

Problem with Emailing the Internal table data as an excel attachment

Hi Friends,
I am facing problem with Emailing an internal table data as an excel file. I am using standard function module "SO_NEW_DOCUMENT_ATT_SEND_API1" which is using SOLI structure can have record with 255 character length. But my Internal table having each record means after concatenating all the fields it is going to be morethan 450 characters. so i t is not displaying all the data in excel file.
Can somebody help me if there is any other function module or any other way that i need to follow.
thanks for help

You must use the the :
CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB as a field seperator and
CL_ABAP_CHAR_UTILITIES=>CR_LF as a record seperator.
Check this example:

Problem with trigger and mutating table

END;
Can anyone help me?

You are trying to lookup data from qw_qualifier you are currently modifying. You could see the data in a inconsistent way and Oracle is protecting you from it.
You could read here about how to program around this problem.
But: your table design seems questionable. You have two records for qw_qualifier and you are trying to log it into one qw_qualifier_log record. Maybe you could fix that, and the need for querying the same table as you are updating is removed.

Rob.

Problem with reflection in Generics

I'm using the Prototype compiler for JSR-014 and I am having a big problem with reflection. In the simplest case
class n<T> {
    void go() {
     this.getGenericType().getTypeParameters();
     this.getClass().getGenericInterfaces();
}I get a "cannot resolve symbol" on both lines. A glance at the jar included with the prototype shows why: all the collection classes are there, and a lot of the java.lang types, but not java.lang.Class and none of the java.lang.reflection classes.
So what gives? Is reflection not supported yet? (gaak!) Is there another jar I am supposed to download?
Thanks

Schapel is right.
but also
The signatures for fields and methods will include the generic types.
If you really wanted to, this would work.
get the Class's ClassLoader,
work out the name of the Class's file, and get an inputStream to this resource (from the classloader). (This bit works because I use as a diagnostics tool to see if classes are loaded from my jar, or my patches directory - see below).
Write some stuff to read the class file and parse out the generic signatures for the things you are interested in.
I don't think this last part would fit into anyones definition of "fun", however the specs are all available, and it may turn out simpler than at first appearances.
Here's the code I use to get the location of where a class is loaded from.
    static URL getLoadPath(Class theClass) {
        StringBuffer resourcename = new StringBuffer(theClass.getName());
        for(int i=0;i < resourcename.length(); i++) {
            if(resourcename.charAt(i) == '.') {
                resourcename.setCharAt(i,'/');
        resourcename.append(".class");
        return theClass.getClassLoader().getResource(resourcename.toString());
    }if you use getResourceAsStream() in place of getResource() you will have the .class file as an inputStream which you can read and parse.
Have Fun

Problem with MultiLeadSelection in a table

Hi All,
I am still having the problem with the multilead selection in a table.
I am setting the table properties to multi and I have an event handler for the onaction property, named as leadselection.
I am writing the code below for the event handler.
public void onActionLeadSelect(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
int selectedRow = firstNode.nodeOPENITEMS_open().getLeadSelection();
    int sizeOfOpen = wdContext.nodeOPENITEMS_open().size();
     IOPENITEMS_openElement element = (IOPENITEMS_openElement)firstNode.nodeOPENITEMS_open().getElementAt(selectedRow);
     for(int i=0;i<wdContext.nodeOPENITEMS_open().size();i++){
          if(wdContext.nodeOPENITEMS_open().isMultiSelected(i)||selectedRow == i){
               wdContext.currentContextElement().setMultiDocNumber(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getDOC_NO());
               wdContext.currentContextElement().setMultiItemno(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getITEM());
               wdContext.currentContextElement().setMultiRepItem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getREP_ITEM());
               wdContext.currentContextElement().setMultiSubitem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getSUB_ITEM());
What i am trying to do is..On multiselection or on single leaad selection, I should pass the whole amount to the BAPI or the amount related to only the leadselection.
But when I am trying to run..this code..I am nt able to select in a multiple way..and more over if I press ctrl then I am able to make the other rows highlighted with orange color..but not normally and after making them highlighted also i am not able to pass the amount for all the selected rows..together..
Kindly suggest me..something..
Regards
DK

Hi,
Try this ,
for(int i=0;i<wdContext.nodeOPENITEMS_open().size();i++){
if(wdContext.nodeOPENITEMS_open().isMultiSelected(i)){
wdContext.currentContextElement().setMultiDocNumber(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getDOC_NO());
wdContext.currentContextElement().setMultiItemno(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getITEM());
wdContext.currentContextElement().setMultiRepItem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getREP_ITEM());
wdContext.currentContextElement().setMultiSubitem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getSUB_ITEM());
If you use the selectedRow variable in if condition, it will fetch only one row from table. Because the getLeadSelection() method gives the number of row which got selection on first click before pressing Ctrl key. So you can get only one value for leadselect. that's why the if loop failure for other selected rows.

Problems with RowSelection in adf table

I have problems with selection of a row in a adf table. Even though I have set the property : rowSelection="single" , when i select a row, the two other rows that follow, get selected too. For example I have 10 records an when i select the 7th row, the 8th and 9th row are also selected. This doesn't happen with the first rows.
Also when i evaluate an attribute on selectionListener, it is always getting just the one from the first row.

I have two panelBox, one for a set of options with commandMenuItem and the second one wich shows the result in a table. The first commandMenuItem generate records an show them in the table. Here i got no problem with selection. The third commandMenuItem execute a log of the records generated, here is the problem.
Thes two pages are part o a template, the template has a panelSpliter, in the right are the set of commandMenuItem an in the second is the part that i can edit.
I have also drag an drop from the datacontrol again and have the same result

Performance problem with query on bkpf table

hi good morning all ,
i ahave a performance problem with a below query on bkpf table .
SELECT bukrs
           belnr
           gjahr
      FROM bkpf
      INTO TABLE ist_bkpf_temp
     WHERE budat IN s_budat.
is ther any possibility to improve the performanece by using index .
plz help me ,
thanks in advance ,
regards ,
srinivas

hi,
if u can add bukrs as input field or if u have bukrs as part of any other internal table to filter out the data u can use:
for ex:
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
WHERE budat IN s_budat
    and    bukrs in s_bukrs.
or
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
for all entries in itab
WHERE budat IN s_budat
    and bukrs = itab-bukrs.
Just see , if it is possible to do any one of the above?? It has to be verified with ur requirement.

Problem with the regeneration of Table Maintenance

My Scenario is like this.
I have to add a Long Description with a length of 4000 Charecters. For this I have created in my Z TAble ZINT INT2 5 and ZZLONG_DESC LCHR 4000. I have activated the ZTABLE. I have Adjusted & Activated the Database by using Data Base Utility. I have regenerated the Table Maintenance (SM30), here my concern is I am not able to see the ZZLONG_DESC Field for Value Entry. I have seen all other Fields are ready for input, except this field. How do you achieve this.
What ever I will type in ZZLONG_DESC, when I say SAVE it should be available in ZTABLE.
How to read the Long TExt for 4000 charecters, is it possible using the Function Module "READ_TEXT". Please suggest me.
Thanks & Regards,
Sivaram Kandula

Hi Sivaram,
Yes, there is a problem with fields of long lengths. But, can I know exactly what type of table maintenance u have generated? Is it a one step or a two step? I suggest you to go ahead with creation of two step table maintenance. Then you will definitely see that in the second screen means, when you click on "New Entries" you should be able to see it. Plz have a try at this and let me know with the update. Hope this should work out.
Otherwise, better to go with Text table concept. Hope you got it.

Real Time Simulation, problem with the 3D Lookup table

Hello,
I have a problem with LabVIEW RT. I want to read under the parameters of temperature, time and voltage, the current out of a matrix.
The matrices differ only in the temperature (first entry in a matrix).
If the 3D Lookup table only get one matrix, I often get "Not a Number" as result. But not always, although the parameters remain the same.
If the 3D Lookup table gets three or more matrices, the result never be "Not a Number". But the 2 other matrices are "dummys" filled up with zeros, expect the temperature. Also the problem appears only if I start the test sequence as Startup on the RT-System. If I start the test sequence from the Front Panel, the 3D Lookup table works well, whether one or more than three matrices!
Its confusing, I know ^^
The appendices contains pictures from a matrix an from the Block Diagram

Hello salomon,
The 3D lookup table is not generated in my code, but is invoked as a constant. I examine the behavior of electrical loads in the cars. Consumers were in a climate chamber measured at various temperatures and these values were packed into a 3D lookup.
Helps you even further? : D

Problem with refresh issue in Table Overflow Area for LOV in edit mode

Hi Friends,
I am facing a problem with LOV if i keep this in Table Overflow area,
When i select a Employee name from the List of Value clicking on select button it will not refresh the lov to display the currently selected Employee Name, but if i click on show and hide link of Table overflow the selected employee name will be displayed.
But the if move the same lov item from Table Overflow area to Table layout it works fine.
I tried my best to look into this but i could not, can any one suggest me what i need to do for this refresh issue.
Regards,
Rahul

Hello Rahul,
Strange, it's working for me.
I assume you added Employees as reference entity to your updatable entity in your ViewObject.
Did you uncheck "Key attribute" in EmployeeId of your reference entity?
Anything in the log?

Problem with Vertical scroll in table control

Dear All,
I am facing a problem with table control in module pool program. currently it displays 6 lines, but it does not display the vertical scroll button, even though when I fill data in the six rows and hit enter.
I have set the vertical scroll option on the table control properties also.
Can someone help me by sending some sample code?
Thanks,
Amit Goyal

HI Amit ,
If you have already selected the properties of vertical and horizontal scroll bar then no other operations needed .. if the number of rows increases then that of the table control , you will automatically see the Vertical scroll in your table control ..
if still you dont see it then write back ..
Reward if helpful !
Thanks

Problems with extension of generic abstract class

Hello,
I'm having some problems with the extension of a generic abstract class. The compiler tells me I have not implemented an abstract method but I think I have. I have defined the following interface/class hierarchy:
public interface Mutator<T extends Individual<S>, S> {
     public void apply( T<S> ind );
public abstract class AbstractMutator<T extends Individual<S>, S> implements Mutator<T, S> {
     public abstract void apply( T<S> ind );
}Now I implement AbstractMutator as such:
public class BinaryMutator extends AbstractMutator<StringIndividual<Integer>, Integer> {
     public void apply( StringIndividual<Integer> ind ) { ... }
}The compiler says:
BinaryMutator.java:3: ga.BinaryMutator is not abstract and does not override abstract method apply(ga.Individual<java.lang.Integer>) in ga.AbstractMutator
Why does it say the signature of the abstract method is apply(Individual<Integer>) if I have typed the superclass as StringIndividual<Integer>?
Thanks.

Yes, but the abstract method takes an arg of type <T extends Individual>. So it takes an Individual or a subclass thereof, depending on how I parameterise the class, right? StringIndividual is a subclass of Individual. So if I specify T to be StringIndividual, doesn't the method then take an arg of type StringIndividual?

Problems with saving Word 2007 table as PDF

I have a table in MS Word 2007 with some merged cells. If I use the Save as ... PDF or XPS option in Word 2007 to save this document as a PDF, the resulting PDF has a table with a discontinuous table grid. The table lines around the cells are broken.
Is this a problem with the Word table or does the Save as PDF command not work well with tables.
Thanks,
Karl Smith

What versions of both programs and how did you create the PDF? Can you post an example of the PDF?

Problems with layout and printing tables

Hello,
my first ADOBE-Form "projekt" makes more problems than expected, especially with the layout.
Layout Problem 1:
I want to print the data of a table (thats my only parameter in the interface and the table itself is deep structures with other tables). So I have bound the "standard" subform (the one ADOBE inserts automatically" to the table and selected that the subform is repeated after every record.
Anyhow ADOBE processes only the first record of this table.
Maybe the reason is, that I need to display the data of one record on two pages. So I created two pages each with the "standard" subform and bounded both to the table.
What am I doing wrong? Do i have to do the page split another way?
Layout Problem 2:
I have a text field with multiple lines allowed. But it overwrites the content of the object, that comes below.
Its the same with my other subforms for table data.
How can I tell the system, that an object needs to be pushed downside on the page, if the context above needs more space?
Thanks in advance for your answers!
Regards,
Frank

Yeah, you say it
subforms and they "flowing" etc. properties are killing me, but after some hours I think I got the concept.
The form looks quite well, everything is pushed downwards if an item above gets expanded.
But one problem remains: this form only prints the very first record of my table.
I have no problems with the tables nested inside the main table. They work perfectly and everything is fine there!
But I cant tell the form to print my other records...
I somehow played around and made it work, but then the next record was not on the next page but directly after the subform created by the context area (if this terminology is correct).
I played around even further and created a paging with reference to the context area, but then the first page looked quite odd (page 2, 3, 4... looks perfect).
I tried to fix also this and then I somehow messed up my form and could not undo my changes (it was only a "to play with" copy...)
Just to explain it again:
I have one table (lets call it the "main table" because its the import parameter of the interface) and inside this table are other nested tables.
I want to print one record of the "main table" across 2 pages and after that the next record of the "main table" should be printed beginning at the 3rd page.
As I said, the two pages look wonderful (even though I have not yet covered the issue of what should happen, two pages are not enough for one record of the "main table"). but as soon as I try to display the next records of the "main table" as well, i am stucked in unpredictable layout problems.
I cant believe that I try anything extraordinary. Lets hope that I can solve this with your very appreciated help.
Thanks in advance Otto!!!
And kind regards, Frank
