Using multiple joiners in a mapping

Is it possible to use multiple joiners in a mapping? Or should we use a single joiner with multiple INGROUPs?
Here is a scenario.
I have tables A, B and C and I want to join all three
I joined A and B with joiner1
Now I use joiner2 to join table C with output of first joiner
The mapping did not give any error, but when I executed, it consumed all temp table space and disk usage became 100%

Hi,
Usually this Temp issue comes in picture when u have some problem with your join its not a issue with number of joiners, i guess its a problem with you join condition which must be generating some Cartesian more number of rows than expected , it happens when u miss some join condition , please review you join condition again. you may want to run the intermediate results of the joins individually , run the first join query and see what happens , please check the explain plan when you do this some times poor execution plan may kill you box and temp spaces

How do I use multiple local workspaces for the same website in VS2013?

For quite some time I've been using VS2010 with multiple workspaces mapped from the same TFS branch to test different variants of a website in parallel. The internal web server (Cassini) seems quite happy to run multiple versions and simply maps a new port
number for the second and subsequent instances that start up.
We are now looking to move to VS2013, so have to use IISExpress since the 'internal' web server is no longer provided.
How do I configure things so that if I open a single workspace, IISExpress runs against that workspace using the default port number (specified in the solution), but if I open a second instance in a different workspace it correctly uses a new port number
and working folder. Do I need to invoke IISExpress using the command line (presumably from each workspace) and specify the relevant defaults or is there some way to enter this in the local config file for IISExpress?
My initial attempt at editing to config file resulted in the 2nd and subsequent instance using the same physicalfolder as the first instance, presumably because the speficied site name and port number are the same!

Hello,
Thank you for your post.
I am afraid that the issue is out of support range of VS General Question forum which mainly discusses
the usage of Visual Studio IDE such as WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Based on your description, I suggest that you can consult your issue on ASP.NET forum:

How to multiple layers in the MAP web item?

Hi experts,
I'm working on a demo with BWGIS. I encounter several problems with the MAP web item.
My demo:
QA results visualized on global (region object - e.g. Europe, Asia), country (country object) and plant level. Use geo-drilldown to navigate into the lower layers functionality to get from the global view to the countries within one region and plants within one country.
My settings:
Region is a static geo-characteristic. For region I used the cont200.shp file. Also country is a static geo-characteristic, here I used cntry200.shp. For test I used ARCGIS to draw (points) some example plants in the country shape file. I uploaded this shape file to the plant object (also static).
My success:
I'm able to display the QA results in a separate global or country view within the 3.x Web template.
My problems:
A) The map web item in 7.0 does not display any data: it looks like no link can be made between the query result and graphic although we installed the latest IGS.
B) I'm not able to drilldown from a global view to the countries within one region (doubleclick on one region in global view) within the 3.x Analyzer and 3.x Web template.
My first question is about the concept of BWGIS:
1) I want to use geo-drilldown (double-click) to navigate to the lower layers. For example in the global view I see only the QA result per region (shape file of region object) -> doubleclick on Europe, I expect to zoom in to Europe and see the QA results for all the countries in Europe (shape file of country object). How do I modell this in the web application designer?
alt. 1a: 1 map 1 layer - 1 dataprovider - underneath 1 query with region and country in the row is not allowed, so how to navigate between the two geo-relevant objects?
alt. 1b: 1 map - 2 layers (2 shape files) - 2 dataproviders - 2 queries, one with QA result per region and one per country -> in that case both will be displayed at the same time, is not what I want. How to navigate between the two layers?
alt. other ?
2) I know how to make maps with multiple layers in ARCGIS, but do I need this for BWGIS, because one layer is one shape file? So do multiple layers in the map web item correspond to multiple layers in a ESRI ArcMap Document.
More specific questions:
3) Is there a lot of experience with the map web item in 7.0, documentation and working examples? Are there known problems (I can't find anything in sap notes). Is it better to still use the 3.5 Web Application Designer for this?
4) There is very little information on SAP help, SDN and other forums about BEx Map and moreover the MAP web item. Does anyone have more documentation for me?
Thanks in advance.
With kind regards,
Rick Stoll

How to use multiple Interfaces for the same BS?

Hi @ ,
Is it possible to have a scenarion where i am using multiple interfaces in the same BS based upon some conditional field in the message.
I amnot able to get the solution I know with condition editor I can have multiple receivers but in my scenarion based upon message fiels i have to decide which BAPI to be used and wht mapping and then post it to the same System
Any help will be highly rewarded
Regards

Hi-
Yes it is possible you can use multimapping for mapping the interfaces.
To know more about multimapping see

Using multiple timer in the same SessionBean

Hello,
Is it possible to use multiple timer in the same Stateless Session Bean. In my application a user can schedule some task to execute. To do so I was thinking of creating a Session Bean which would create calendar timer on user request and, when one of the timer expires, retrieve the task to execute thanks to the information stored in the timer.
When I tried the solution explained above, it seems that the @timeout method is synchronized on 1 timer. For example if I create a timer that will be executed every 10 seconds and another one executed every 30 seconds, the timeout callback is called every 30 seconds but 4 times.
My code looks like that :
@Stateless
@LocalBean
public class TimeManager {
    public void onUserRequest(ScheduleExpression expression) {
        Timer timer = timerService.createCalendarTimer(expression, timerCfg);
    @Timeout
    void timeout(Timer timer) {
        logger.log(Level.INFO, (String) timer.getInfo());
}Is there a way to do what I want?
Thank you

This doesn't make any sense to me. If i were to write a bunch of schemas for a particular applicaion, would
I have them all in the same namespace? You would normally have one schema that describes the information model associated with the one namespace that the different documents in your application use.
If so, why can't I load more than one in the same name space?The parser chooses the schema based on the namespace alone. There is no other information used to decide which schema to use, so you can only have one schema for the namespace.
They all have different root elements.You can have different root elements in the one schema.
I don't even need the namespaces, but I can't
figure out how to get rid of them (the schema isn't valid with out them according to XML Spy). You can set the schema explicitily before parsing, but not (AFAIK) set after parsing has begun, except by using the mapping of namespace to schema location.
I have also tried to use the external-noNameSpaceSchemaLocationproperty, but it doesn't seem like you can pass in an array of schemas to that one. It only expects a
String as the Object you pass in to setProperty. Yes, you can only validate a document against the one schema.
So, how can I load all my schemas so I don't have to reference them in the XML documents? Either combine your schemas so you have one schema for your namespace that validates elements which are defined in that namespace (the formal/correct way of doing it), or construct a filter that inserts a PI to point to the schema once the root element is opened (the pragmatic/bit of a hack way of doing it).

Using multiple EIM tables in single process section

Hi ,
Often we come across a situation where in some required columns are mapped in one EIM table and some mapped in the other EIM table mapped to a given base table.
Is there a way wherein we can utilize multiple EIM table having mapping of a base table under the same process section with only base table parameter poiting to the target table.?
Regards,
Ashutosh

Hi,
May be I have misinterpreted what has been mentioned in the EIM admin guide.In the page 41 chapter EIM Configuration File the following has been mentioned for the TABLE paramter.Therefore i was wondering if we can use more than one table in a given process section in IFB file.
[TABLE           Required. Specifies the name of an EIM table used in this process.
                     *Multiple TABLE parameters may be used to define a process using*
                     *more than one table*.
                     Example:
                     TYPE = EXPORT
                     BATCH = 101
                     TABLE = EIM_ACCOUNT
                     EXPORT MATCHES = S_ORG_EXT, (NAME > A)
NOTE: For performance reasons, you should limit the number of
tables to export or merge in a single process section to five tables or
fewer.]

Use thinkvantage access connections to map a network drive

Is it possible to use thinkvantage access connections to map a network drive. I have three different basic sites (home, work1, work2) with network drives that I would like to access depending on the site.
1) I wonder if it is possible to configure thinkvantage access connections to automatically map the network resources through a connection profile?
2) I wonder if it is possible to configure thinkvantage access connections to automatically map the network resources through a connection profile that is based on vpn connection?
thanks in advance
sincerely, anders

Hi,
directly it's not possible for Access Connection to reconfigure your network drives.
However, there is one really cool part of Access Connection, that might be realy suitable for your situation. This part is the script/application, that can be executed when a profile gets applied.
So for your situation I can imagine, that you create a .bat file, that contains something like this:
net use * /DELETE /YES
net use Z: \\computer name\share name
The first part will delete all maped drives. The second part will establish connection that you want to use. Of course you can multiply the last part, so that you can configure multiple connections.
Please let me know, if this helps.
Cheers

How to set #HOST# variable used in Chart template using Multiple Domains?

I have a extended question to How can I set #HOST# variable referenced in the Chart template?
In addition to the Proxy layer, we are looking to use multiple sub-domain names into the same Oracle APEX instance (through the one DAD) each mapped to a different application id. Therefore I don't think the solution in the link will work for me - as this embeds a single domain name in the DADS.CONF.
Two questions:
- Is it possible to set the "HTTP_HOST" in "dads.conf" using an existing HTTP Header value? - my proxy can pass on the original domain as "HTTP_X_FORWARDED_HOST". So if it was possible to use (say: using whatever form/syntax of parameterisation is available) ?
>
PlsqlCGIEnvironmentList HTTP_HOST=%{HTTP_X_FORWARDED_HOST}
>
If it can then that would work for me. It would be great if modl_plsql handled this out of the box as I understand the "X-FORWARDED" approach is pretty standard in the proxy world including passing on original IP addresses. Hitting an phpinfo() site shows headers
>
HTTP_X_FORWARDED_FOR     192.168.2.100
HTTP_X_FORWARDED_HOST     dev.mycompany.com:443
HTTP_X_FORWARDED_SERVER     mycompany.com
>
- Alternatively is it possible in APEX environment to set the #HOST# from the HTTP Header "HTTP_X_FORWARDED_HOST" if it exists for all requests?
Thanks

Hi Donna,
changing the CGI environment variables HTTP_HOST, REQUEST_PROTOCOL and SERVER_PORT is the correct way how to resolve this, because it appears that your hiding the web server where you have installed mod_plsql or EPG by a different outside facing web server (also called reverse proxy). That's why APEX gets the host name, protocol and port of the internal web server, but should actually get the values of your reverse proxy web server. Can can fix that by changing the following CGI environment variables.
HTTP_HOST should just contain the domain name (no protocol or port). For example: www.oracle.com
REQUEST_PROTOCOL should contain http or https
SERVER_PORT should be the port for https
I don't want to add a new cgi variable called HOST because HOST sounds so generic and it might interfere with something else running in our environment. Or, I don't want to change the plsql cgi environment variable (such as HTTP_HOST) because many developers may use owa_util.get_cgi_env('HTTP_HOST') to get the current server. If the SERVER_PORT is part of the #HOST# then what could I change it to if it needs to be null. If you leave it blank, then the default SERVER_PORT comes from the CGI variables.The value of HTTP_HOST is wrong anyway and points to your internal web server, but I assume your developers actually want to get the host name of your external web server if they use it to generate absolute URLs. That's why I wouldn't bother and set it to the correct host name.

Get Siri to set location reminders (using multiple reminder lists)

I found a way to get Siri to set location reminders using multiple reminder lists (but you can just use one list too):
First make additional lists in the reminder app: click list button (the lines on the left) > edit > create new list > done. Make as many as you want. I have grocery, home, personal, business, family.
Let's say you want a reminder to pick up apples when you get to the apple store. You must add the location in your contacts to your name in contacts.
Do the following:
In maps app find the location with search.
Tap the blue arrow > Add to contacts > Add to existing contact
Choose your name in contacts. It will be added under your address for home or work so you will need to edit it:
Click Edit.
Click on the small label on the left of the new address - it will just say "address"
Scroll to bottom of page and click on Create custom label
Enter the location name like "Apple Store". Click Done.
Important Note: You will need to delete the url it adds under your home url section and maybe other things it messes up with the new contact info instead of yours - so check all the fields each time you do this.
To make a location based reminder using a specific list you must open that list yourself - Siri will not open it for you.
Example:
Open grocery list yourself in the reminders app
Tell Siri something like: "remind me to pick up apples" (Do not mention the location yet - if you do it will not work)
Siri will ask: "When should I remind you?"
Say: "When I get to the apple store"
Siri will say she will remind you and you will see the location reminder in the grocery list.
This is how it works for me but if you know an easier way let me know! This is beta so I'm sure it will get easier.

I have one thing to add. You don't have to open the list manually. Tell Siri: "Add to my <listname> list". For example, if you have a list named "Work", tell Siri: "Add to my work list". Siri will reply, "What should I add to your 'Personal' list?
and you can continue from there.
There is a syntax for doing all this in one sentence, but I find it only works about half the time. Too many fields for Siri to parse in her current Beta stage

How can I add multiple, successive destinations in "Maps" such as on a delivery trip with several stops ?

How can I add multiple, successive destinations in"Maps" such as on a delivery trip with multiple stops and so needing driving directions i.e. set up a route ?

Maps help:
Mark a location with a pin
You can drop a pin on a location to get directions or help you find it again.
Open Maps
On your map, go to the location you want to mark with a pin.
Choose View > Drop Pin. If the pin isn’t exactly where you want it, put the pointer on it and hold down the button until the pin “hops.” Drag the pin into place, then release the button.
To see information about a location, click its pin, then click the Info button. To close the Info window, click outside of it.
To remove a pin, select it, then choose View > Clear Pin.
Get directions
Using Maps, you can get directions to help you navigate on foot or behind the wheel. Once you've decided where you're going, click the Share button to send your map and directions to your iPhone. (Your iPhone must have iOS 7 and be signed into the same iCloud account as your Mac.)
Open Maps
Do one of the following:
Click Directions to open the directions sidebar, then enter the starting and ending locations.
On the map, click a pin to display its info banner, click the info button to see more info, then choose “Get Directions.” (If your starting location doesn't have a pin, you can Control-click or tap it with two fingers, then choose Drop Pin.)
Click either the car (driving directions) or person (walking directions).
If multiple routes appear on the map, click the one you want to take.
To zoom in on a turn, click it in the directions sidebar.
To close or reopen the directions sidebar, click Directions in the toolbar.

What is the Use of Imported Archives in Mapping Objects

Hi All,
What is the Use of Imported Archives in Mapping Objects ( IR )
Regards
Vamsi

Hi Vamsi,
When we are doing JAVA , XSLT mappings we have to do import archievs
after developing the JAva mapping in NWDS and create jar file come back to IR under imported archieves we will import the jar file.
Similarly XSLT als make the zip and import under imported archieves
Also when we have any java packages ,import it under archieves and make them to use in UDF

System Landscape using multiple clients scenario for BW

Hi Friends,
I have a scenario where I want to use multiple BW clients based on single server.
I have made client copy of the development server and want to transport the objects
to the target clients.
I am aware that such a scenario works fine in R/3 and infact i have used it
.But in BW when i hit RSA1 I get an error message "you can only use client(010)"-my development client of which copy was made.
The client copy system is 102.
Now I read a thread on sdn which said change client entry in RSADMINA table .I changed it ,but I think its cross client table and hence RSA1 is neither workinging in client copy or the parent system.I reverted back entry in client 102 and saw that development client working again fine like before.(also RSADMINA) value changed in 010.
I have tried to fix it by creating appropriate mappings using SCC4/BD54/SALE/WE20/RZ10
.Also created mapping WE20 for Partner profile and assigned the logica system.
Is it possible to have such a system landscape?
Can anyone give some useful suggestions?

Hi..thanks to all of you....
I think this thing boils down to table RSADMINA where you maintain entry for your client.
The primary key there is 'Customizing ID' and when you specify there "BW" .You can't make another entry for another MANDT with another customizing id.
Whenever u login to any other client and you change entry of MANDT it is going to be reflected to all the clients and thats what is the issue.So you can't mantain mulitple entries as you can't enter two customizing ids. there.
Infact there are many reasons in the background as well which the sap note mentions like common number ranges..etc.
Lastly ..Ofcourse as Siggi said you can have another R/3 or CRM system etc on the same server but no two BW clients.I think SAP should not allow client copy for BW on the same server..it will help some bad efforts
Thanks for the support everyone.
Regards,
Rakesh

Generation/Acquisition using multiple HSDIO PXI 6556 with bi-directional signals

Hi,
I would like to run vectors to test some ICs using multiple (three) PXI6556 cards. The vectors have multiple (>20) bi-directional signals.
Questions:
1. The NI Examples library shows multiple-device generation and acquisition VIs. However, it seems the examples are on single direction signals. Could you show me some example on how to configure bi-directional signals?
2. The pin mapping in the vectors are not in the same order as the HSDIO card pin mapping. Is there an easy way or any tool to help channel mapping? I have 10+ vectors with 90+ digital signals. Manually remapping them is quite tedious.
3. Since we have three PXI6556 cards in the tester, is the "Multi-Device dynamic generation and acquisition" example VI the one to follow? Just to double check if there is any better way to do the configuration.
Thank you for your help!
Jing

hello jcao,
I have adressed your questions individually below:
1. bi-directional examples can be found in two locations Hardware Input and Output >> Modular Instruments >> Demos >> Dynamic Acquisition and Generation Demo.vi and Hardware Input and Output >> Modular Instruments >> Dynamic Acquisition and Generation >> Stimulus and Response Load from HWS File.vi . Both of these examples utilize the bi-directional functionality of our HSDIO cards.
2. The easiest way to map the pins is to use the Digital Waveform Editor software. You can import a VCD (Value Change Dump) file and save it as a NI-HWS file to be imported and used in LabVIEW (the second example above will show you how to use the HWS file). A VCD file should allow you to specify a signal name and assign it to a particular line.
3. The "Multi-Device dynamic generation and acquisition" example VI is the best to follow for syncing across multiple HSDIO devices. The examples use TCLK which is the recomended syncing method. I have also provided a link explaining TClk a little more thoroughly.

Coverage Strategy use multiple Category Structures

Hi AFS Expert,
In the same Coverage Strategy, does it allow to use multiple Category Structures to do the transfer from requirement category to stock category?
E.g Category Structure: AA, BB
"Category Structure AA --> Coverage Strategy CS1 --> Requirement category" transfer to "Category Structure BB --> Coverage Strategy CS1 --> Stock category"
Is it possible to do?
Looking forward your kind advise.
Thanks,
Mag

Hello Mag,
The coverage strategy is configured for a single category structure and it maps the category values of that category structure. We can define the sequence in which the stock categories map the requirement categories. We will not be able to map the requirement category to stock category across category structures.
Hope this information helps.
Regards
