How to use multiple clients within JCO?

Hi,
I'm pretty new to configuring Web Dynpro's with it's JCO connections. I have the following question.
We are using one portal (SAP EP 6.0_640 SP15) and one R/3 system (SAP ECC 5.0) with multiple clients (multiple customers who are all using the same portal).
Do I have to deploy a web dynpro for each client and maintain it's JCO connection for each client?
Or is there another way how I can set this up?
Thanks in advance.
Kind regards,
Dave Arends

Hi Dave,
<b><i>Do I have to deploy a web dynpro for each client and maintain it's JCO connection for each client?

You dont need to deploy a web dynpro for each client . You can use same JCO connection for multiple User ID's ( multiple Clients mean multiple user ID's on the same portal ).
If this is the case then single JCo connection is enough to pull data from R/3 and show on portal page .
Thanks,
Nanda

How to use multiple profiles within the same instance of Thunderbird

About a month ago, I had Thunderbird configured with three profiles,
and all three could be used within a single startup/instance of
Thunderbird. That PC is now gone. I have re-configured the three
profiles on a new PC, but am having trouble making all three
useable within the same instance of Thunderbird. Can you help?
Both PCs are/were Windows-7 64 bit.

Thunderbird only opens on the default if one profile
or
if Profile Manager is instructed to ask at startup it will allow you to choose which Profile to open else it opens on the last Profile used..
So it shows one Profile at a time in one instance of Thunderbird.
However, one Profile can have many mail accounts.
eg: I run 4 mail accounts in one Profile.

How to use multiple tape drive for single filesystem on single client.

How to use Multiple Logos in One Smart Form?

All,
I have a client where they will have 2 logos for, e.g. "Invoicing" and want the form to decide which logo to print (based on plant code).
We are using Smartforms.
They want to use one form and based on the plant code - the form should determine which logo to print in the upper left corner of the invoice - how do you do this?
This is not like having text to print on the form in the same place - my understanding is the logo is NOT some variable you can "clear" in the program and then use the logo you wish to show up on the printout.
Does this have something to do with using multiple layouts within the same form? You define a layout for each logo and then within the Smartform logic determine which layout to print? And if that is true - does someone have sample code of how they determined which layout to use?
Thanks - and as always - points rewarded where helpfull!
Scott

Hi Scott,
Create two Graphics in Smartform window & place them wherver you want in the smart form.
Now in Graphics node, you can find 'Conditions' tab, under this you can give the conditions.
Hope this clue wil help you

How to use multiple JREs (1.5.0_20 and 1.6.0_07) with Internet Explorer 8?

Hi!
Question about the problem mentioned in subject.
I have configured that JNLP opens with 1.5 version, both versions are enabled in Java Control Panel Runtime Settings but when I try to start a desktop java console says:
Java Web Start 1.5.0_22
Using JRE version 1.6.0_07 Java HotSpot(TM) Client VM
And the opening of the desktop creates an exception:
Java Web Start - Invalid Argument Error
TooManyArgumentsException[ Too many arguments supplied: {C:\WINDOWS\Temporary, Internet, Files\Content.IE5\....
I'm trying to open my desktop with 1.5 version and other programs with 1.6 version. What is it that I still need to do? I'm kind of confused with this. Some of my collagues have succeeded with this and some doesn't, with the same configuration.
So the question is, how to use multiple JREs with IE8 so that one application uses 1.5 version and others 1.6 version?

Once you can come up with an actual question, I might look at this more closely.

How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?

Hi All,
Hope to you a very happy new year,
I have two differnt LAP 1300 and 1200 in my network and I need to add theme to the WLC,
I successed to add one of theme by the option 60 in the DHCP pool at the Core SW,
So my quetion is below:
How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
Thanks in Advanced,
Ahmed,

To add to Scott's post. Option 60 would be useful if you needed to put certain types of AP on specific controllers. Otherwise, no real need to use it for the most part.
Though, I do recall an issue a few years ago that some windows machines had issues getting DHCP if option 43 is being returned.
Now, on an IOS switch, you can only configure one option 60 per DHCP scope

How to use multiple selection parameters in the data model

Hi, after have looked all the previous threads about how to use multiple selection parameters , I still have a problem;
I'm using Oracle BI Publisher 10.1.3.3.2 and I'm tried to define more than one multiple selection parameters inside the data template;
Inside a simple SQL queries they work perfectly....but inside the data template I have errors.
My data template is the following (it's very simple...I am just testing how the parameters work):
<dataTemplate name="Test" defaultPackage="bip_departments_2_parameters">
<parameters>
<parameter name="p_dep_2_param" include_in_output="false" datatype="character"/>
<parameter name="p_loc_1_param" include_in_output="false" datatype="character"/>
</parameters>
<dataTrigger name="beforeReport" source="bip_departments_2_parameters.beforeReportTrigger"/>
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
select deptno, dname,loc
from dept
&p_where_clause
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_DEPT" source="Q2">
<element name="deptno" value="deptno"/>
<element name="dname" value="dname"/>
<element name="loc" value="loc"/>
</group>
</dataStructure>
</dataTemplate>
The 2 parameters are based on these LOV:
1) select distinct dname from dept (p_dep_2_param)
2) select distinct loc from dept (p_loc_1_param)
and both of them have checked the "Multiple selection" and "Can select all" boxes
The package I created, in order to use the lexical refence is:
CREATE OR REPLACE package SCOTT.bip_departments_2_parameters
as
p_dep_2_param varchar2(14);
p_loc_1_param varchar2(20);
p_where_clause varchar2(100);
function beforereporttrigger
return boolean;
end bip_departments_2_parameters;
CREATE OR REPLACE package body SCOTT.bip_departments_2_parameters
as
function beforereporttrigger
return boolean
is
l_return boolean := true;
begin
if (p_dep_2_param is not null) --and (p_loc_1_param is not null)
then
p_where_clause := 'where (dname in (' || replace (p_dep_1_param, '''') || ') and loc in (' || replace (p_loc_1_param, '''') || '))';
else
p_where_clause := 'where 1=1';
end if;
return (l_return);
end beforereporttrigger;
end bip_departments_2_parameters;
As you see, I tried to have only one p_where_clause (with more than one parameter inside)....but it doesn't work...
Using only the first parameter (based on deptno (which is number), the p_where_clause is: p_where_clause := 'where (deptno in (' || replace (p_dep_2_param, '''') || '))';
it works perfectly....
Now I don't know if the problem is the datatype, but I noticed that with a single parameter (deptno is number), the lexical refence (inside the data template) works.....with a varchar parameter it doesn't work....
So my questions are these:
1) how can I define the p_where_clause (inside the package) with a single varchar parameter (for example, the department location name)
2) how can I define the p_where_clause using more than one parameter (for example, the department location name and the department name) not number.
Thanks in advance for any suggestion
Alex

Alex,
the missing thing in your example is the fact, that if only one value is selected, the parameter has exact this value like BOSTON. If you choose more than one value, the parameter includes the *'*, so that it looks like *'BOSTON','NEW YORK'*. So you need to check in the package, if there's a *,* in the parameter or not. If yes there's more than one value, if not it's only one value or it's null.
So change your package to (you need to expand your variables)
create or replace package bip_departments_2_parameters
as
p_dep_2_param varchar2(1000);
p_loc_1_param varchar2(1000);
p_where_clause varchar2(1000);
function beforereporttrigger
return boolean;
end bip_departments_2_parameters;
create or replace package body bip_departments_2_parameters
as
function beforereporttrigger
return boolean
is
l_return boolean := true;
begin
p_where_clause := ' ';
if p_dep_2_param is not null then
if instr(p_dep_2_param,',')>0 then
p_where_clause := 'WHERE DNAME in ('||p_dep_2_param||')';
else
p_where_clause := 'WHERE DNAME = '''||p_dep_2_param||'''';
end if;
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || ' AND LOC IN ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || ' AND LOC = '''||p_loc_1_param||'''';
end if;
end if;
else
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || 'WHERE LOC in ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || 'WHERE LOC = '''||p_loc_1_param||'''';
end if;
end if;
end if;
return (l_return);
end beforereporttrigger;
end bip_departments_2_parameters;
I've written a similar example at http://www.oracle.com/global/de/community/bip/tipps/Dynamische_Queries/index.html ... but it's in german.

How to use multiple statements inside the "THEN" block of CASE statement?

Below is the code:
SET @strTempString = case @strKeyMode
WHEN 'AUTO/CYCLE'
THEN @strRefID + '|' + @strRetID
WHEN 'CYCLE'
THEN @strRefID + '|' + @strRetID
WHEN 'COMMERCIAL'
THEN @strRefID + '|' + @strRetID
WHEN 'ISNAP'
THEN set @strFName = ltrim(rtrim((Left(dbo.CleanTheStringAdv(@strFName + ' ', 2) + ' ', 2))))

How to use multiple classes for each form

Hi,
I have created two forms using screen painter and now i want to use different classes for these two forms .
I have declared the Sbo Connection in main class i.e. Set Application ,Connection Context() but while connecting to other classes
for executing the code for that form SAP is not connected to that class.How to use multiple classes functionality i don't able to
do that.Please provide some sample codes for that as it will be more helpful for me to understand.
Thanks & Regards,
Amit

Hi Amit,
In fact, its more advisable to use separate classes for every form that you use. Have one common class, say, for eg., clsMain.cs which has all the connection and connectivity to other classes, wherein, the menu event and item event of this main class, will just be calling the menu / item event of other classes.
The individual functionality of the child classes will be called from the item / menu event of the respective classes.
Item event in clsMain.cs will be as below.
private void oApplication_ItemEvent(string FormUID, ref SAPbouiCOM.ItemEvent pVal, out bool BubbleEvent)
            SAPbouiCOM.Form oForm;
            BubbleEvent = true;
            try
                if ((pVal.FormTypeEx == "My_Form1Type") && (pVal.EventType != SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD))
                    oForm = oApplication.Forms.GetForm("My_FormType", pVal.FormTypeCount);
                    NameSpace.Repots.ClsForm1.ClsForm1_ItemEvent(oApplication, oCompany, oForm, ref pVal, ref BubbleEvent);
                if ((pVal.FormTypeEx == "My_Form2Type") && (pVal.EventType != SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD))
                    oForm = oApplication.Forms.GetForm("My_FormType", pVal.FormTypeCount);
                    NameSpace.Repots.ClsForm1.ClsForm2_ItemEvent(oApplication, oCompany, oForm, ref pVal, ref BubbleEvent);
Now, in the individual classes, you can have their respective item events, which will be called from the main class, and the respective functionalities will occur.
Hope this helps.
Regards,
Satish.

How to delete multiple songs within playlist

Hi does anyone know how to delete multiple songs within a playlist on OS or Mac?? I have reached the limit in songs I can play offliine and would like to delete some of the songs that are on my playlist. For example the last 100 songs. I dont want to indiviually sit here and delete them one by one. Thanks Ray

On ios i think the only way is to edit the playlist by clicking on the three dots. I dont own a mac, but on windows you can hold control and select the songs you want to delete. Or select a song, go to the last song you want to delete, hold shift and click on the song.
