Data Interpolation for Automotive Mapping

Hello all,
I have a lookup table (see attached jpeg) for the main duration pulse (fuel injection) of a diesel engine, every data point (in msec) can be match to its respective speed (top row --RPM) and pressure (leftmost row --BMEP in bar). However, I do not have the complete map and thus I'm missing some points. I was told that LabVIEW has some neat data interpolation VIs that can be apply to this specific case, anyone knows one or knows how to tackle this problem?
Thank you!

Well, if you are running on a LabVIEW FPGA then the Linear Interpolation VI may be of interest. In LabVIEW for the PC the Curve Fitting Express VI or the 2D Interpolation.vi found in the NI Example finder can help out.

Demo data set for flash mapping

As specified in the MapViewer welcome page, what's the demo dataset which i need to import to view the Flash mapping demo.
Any help or suggestions will be appreciated.
Thanks in advance

In 10g, all demo programs are installed via separate companion CD. DM demo programs are part of the companion CD and you need to install the demos from there.

BAdI UC_DATATRANSFER for BCS Mapping in "Load from Data Stream" method

Hello Everyone,
I need some help on finishing up the code for the UC_DATATRANSFER BAdI.
I have looked up in the SDN and other places, but could not get comprehensive breakdown of documentation except for the "F1" documentation available on the BAdI.
So, any help would be appreciated.
The Steps so far completed,
1. Have activated the BAdI and have created the filter value for the BAdI.
2. After the BAdI has been activated, I was able to go into the MAP method and have written the logic for profit center derivation from consolidation hierarchy.
The issue is there are four components for the Map method,
IT_DATA_SOURCE
IS_DATA_TARGET
ES_DATA_TARGET
ET_DATA_TARGET
The data is available from Source system in the table IT_DATA_SOURCE.
But this is not changeable as it is "Importing" type. Whereas the actual ET_DATA_TARGET which is passed over into FINALIZE method of the BAdI is not filled initially.
When I try to do a MOVE-CORRESPONDING from the IT_DATA_TARGET into ET_DATA_TARGET I continuously am getting the short dumps as both the tables length is not the same.
Did anyone else face the same issue as above when trying to do the BAdI implementation for Mapping.
I will really appreciate if any one can provide me a sample code if possible.
Let me know if you need additional information.
Thanks
Dharma.

Hello,
Thanks for looking into the question.
I already had tried doing that, I get the Short dump stating the object tables are not convertible.
When I looked into the table structures, I found out that the table structures "IS_DATA_TARGET", "ES_DATA_TARGET" & "ET_DATA_TARGET" belong to the same category in terms of these structures being flat structures or tables of length 484 as per the debugger.
Whereas the structure "IT_DATA_SOURCE" has the length 404.
Due to this reason when I say,
ET_DATA_TARGET = IT_DATA_SOURCE, I keep getting the short dumps.
Also, is your consolidation process legal or managerial.
Our Consolidation process is legal and we have the Company and Profit Center fields assigned to the Consolidation Unit role in the Data Basis definition.
Can you please let me know what is the structures length in your system.
Thanks
Dharma.

Date Format on OWB 11.1.0.7 to use for input parameter for a mapping

All,
What is the Date Format on OWB 11.1.0.7 to use for passing in an input parameter for a mapping to execute?
I have tried '01-01-2010','01-JAN-2010','01.01.2010', 01/01/2010 and I get the following error:
Error RPE-01003: An infrastructure condition prevented the request from completing.

I am using a Mapping Input parameter object and have a START_DATE_IN as a DATE and an END_DATE_IN as a DATE
Any information you could provide would be greatly appreciated.
Thanks,
Shaun

Hello Shaun,
The function wb_rt_conversions.from_date is (at least in OWB10.2) overloaded and can with input-types as
date, timestamp_unconstrained, timestamp_tz_unconstrained, timestamp_ltz_unconstrained or varchar2.
If it doesn't work with varchar2 I would try Date:
For example: to_date('2010-01-01','YYYY-MM-DD')
I also found this thread:

How to Cache Data from database for java mapping ?

Hi
I have a scenario where i have to dynamically query a huge table in some other database from java mapping code.
Therefore instead of making a new Database trip everytime is there a mechanism by which i can cache the entire table contents into XI first and then use this cache for looking up data through my java mapping.
Any other alternative also welcome which would give best performance.
Please Suggest
regards
Nilesh Taunk.

Hi Nilesh,
I am not sure if you can actually cache the table in XI. You will have to look up directly from your Database everytime your mapping excecutes.
To perform DB lookup during mapping very efficiently, I would suggest that you take a look at this blog,
/people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
Also, instead of doing the DB look up in mapping, you can also use your JDBC adapter as a sender and collect the information you want from your DB,
If you are using your JDBC as a sender, then your JDBC will poll over your database and select the rows that satisfy your Select Query. Also, there is another field in your JDBC adapter that is very important and that is the Update satatement. Once your JDBC adapter executes your select query and selects rows from the database, you might not need those rows to be selected again. In this csse, you can use the Update statement to update the database.
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm
The choice between a JDBC sender adapter , and the DB lookup will have to be on the basis of your requirements.

How can i use exisitng user data(Id, password) for user mapping

Hi All,
For User mapping , we can import user mapping data for many users from user administration. and for each user
we can maintain mapping data in the standard format.
eg:
[User]
uid=user2
$usermapping$:BCE:user=ext_user2
$usermapping$:BCE:mappedpassword=password
i am clear till this point.
this all works if we know the userid and passowrd on the system 'BCE'.the passwords on the system 'BCE', are encrypted . so there is no chance for me to know the passwords.
so how can i use the existed userid/passowrd on the system 'BCE' for the mapped user and mapped password on the portal while doing usermapping.
Thanks in Advance,
Lakshmi

Hi,
I think this should work.
1. Setup SSO with SAP logon tickets first. How to do this is described many places, e.g. http://help.sap.com/saphelp_nw04/helpdata/en/d3/41c8ecb31d11d5993800508b6b8b11/content.htm
This SSO will not work at first, because the username is different in the back-end system. So what you need to do is to get the back-end username into the ticket (don't need a password because that is done by the SAP logon ticket)
2. Create a portal component which uses the usermanagement API to create a usermapping which only consists of the username and a blank password. You can do this manually I think if you have no reference system defined.
IUserMappingService umap =(IUserMappingService)PortalRuntime.getRuntimeResources().getService(IUserMappingService.KEY);
//this is the currently logged in user. You might another user
IUserContext user = request.getUser();
//Get the existing data (think it can be null)
IUserMappingData userMapping=umap.getMappingData(systemAlias, user);
HashMap map = new HashMap();
                         map.put(IUserMappingService.UMAP_KEY_USER, backEndUserName);
//add blank password               map.put(IUserMappingService.UMAP_KEY_PASSWORD, "");
//store the values                    userMapping.storeLogonData(map);
Voila, this should allow you to do SSO using SAP logon tickets, but with another name that you use against the portal. I am uncertain if this will work if you have multiple usermappings in the sap logon ticket
PS since the sap logon ticket is issued at logon time, you need to relogon to get the changes done by the code

Source Data for Import Map

I inherited some MDM work from a consultant who rolled off our SRM project. He did not leave any source input files to use when making changes to maps, and I read in the SAP MDM Guides that you should always revert back to your original source file when making map changes so you don't lose any mappings (if the newer source file does not contain every segment that the original did, etc).
Am I off base? Is there a safe way to make map changes without having the original source file?
Thank you in advance,
Keith

Hi Keith,
You are absolutely right. This is a common problem which is being faced while subsequent loads into MDM. The problem is that generally the Map is created in Import manager and then if more values come in for value mapping or more fields are mapped due to a new business requirement, then the map sometimes throws a problem of Map being out of date.
The solution that we came out for this was a creation of Value mapping template ( you can also include the field mapping). This would have the complete list of fields and values in one map. Also if some new value is getting added, then firstly add in the template and then Map it in the original Map.
Now in your case, you can either go and create a Template or else, use the SAVE UPDATE option present in Import Manager everytime you face an exception via MDIS. SAVE UPDATE will help you update the additional mapping onto the original map and then if a similar file comes in again, it will processed successfully via MDIS.
You can refer to my Article on this:
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/80ad0cff-19ef-2b10-54b7-d4c7eb4390dd

In case they are kidnapped there, i would like to know the last position. I am getting an error that google maps is not available so i asusme there is no map data. Wout it be at least for such cases be possible to get longitude and latitude instead of nothing ?
Thanks for ideas / suggestions

Access af:table values from JavaScript array (for google maps task)

Hi!
I have JSP page with af:table where latitude and longitude for google maps are stored. I am using these tutorial [https://blogs.oracle.com/middleware/entry/integrating_google_maps_with_adf] and I know how to access latitude and longitude from output text (for one point). Now i need to do something similar with loop for all table rows. How can I achieve this?
I have JavaScript code which uses Google Maps API and can display many points on one map. Also I have longitude and latitude data in af:table (bindings), each table row has one point. My task is to take data from af:table and pass it to JavaScript.
May be it is better to use managed bean as you said. Firstly I will access binding data from managed bean. Then I have to pass this data to JavaScript method? Can you suggest some example? I have "Using JavaScript in ADF Faces Rich Client Applications"

My table is there :

Data Migration for Open Purchase Order

Hi, All,
Is there anyone know how to Count the volume for Open Purchase Order. What's the normal strategy for the Data Migration and Cut-over stage?
My client want to know how many Open Purchase Order in the legacy system and then determine manual or automatic data migration. If manual, how to do? If automatic, how to do? Because all materials and vendors, plants are different number. How to track? How to find out to match between new and old?
Thank you very much

JC,
Sounds a bit early to be making decisions about the realization phase. It doesn't sound like you have finished the Blueprinting phase yet, much less the testing phase.
Anyhow, in my experience I typically use LSMW (Legacy system migration workbench) to load MM master data (material masters), Inventory (WIP, RM, FG, etc) Purchasing Master data (Vendors, Purchase Info Records, Source Lists, Quota Arrangements), and Purchasing transactional documents (POs, PurReqs, Scheduling Agreements, etc). Depending on the complexity and volume of data, it may be necessary to write custom programs to load the data. You will find this out during your requirements gathering.
It is uncommon but possible to load all of these data manually. I have never run across a client that wants to pay a consultant's hourly rate to sit at a terminal to peck away loading master data, so if the client intends to have his own users enter the data manually, the project manager should make provision that there will be qualified TRAINED client employees available for this data entry. I did help with a portion of a conversion once manually; of Sales Credits, but there were only about 30 SD docs to load. I did this the evening before go-live day, while I was waiting for some of my LSMW projects to complete in the background.
A good opportunity to 'practice' your data loads is right after you have completed your development and customization, and you have gotten the approval from the client to proceed from the pilot build to the full test environment. Once you have moved your workbench and customization into the client's test environment, but before integration testing, you can mass load all, or a substantial portion of your conversion data into the qual system. You can treat it like a dry run for go-live, and fine tune your processes, as well as your LSMW projects.
Yes, it is good practice to generate comparisons between legacy and SAP even if the client doesn't ask for it. For Purchase orders on the SAP side, you could use any of the standard SAP Purchasing reports, such as ME2W, ME2M, ME2C, ME2L, ME2N. If these reports do not meet the requirements of the client, you could write a query to display the loaded data, or have an ABAPer write a custom report.
You didn't ask, but you should also do comparisons of ALL loaded data - including master data.
It sounds like you are implying that the client wants YOU to extract the legacy data. For an SAP consultant, this is not very realistic (unless the legacy system is another SAP system). Most of us do not understand the workings of the myriad legacy systems. The client is usually expected to produce one or more legacy system technical experts for you to liase with. You normally negotiate with the technical expert about every facet of of the data migration. In addition, you will liase with business users, who will help you and the implementation team to logically validate that the final solution (turnkey SAP production system, fully loaded with data) will meet the client's business needs.
Finally, you mentioned how do you track the mapping of master data between legacy and SAP. There are many ways to do this. I normally try to get the legacy person do the conversion on his end, eg, when he gives you the load file, you would like to have already translated the master data and inserted the SAP relevant values into the file. If this is not possible, I usually use MS Access databases to maintain a master map, and I perform the mapping on a PC. If your data package is small, you can probably get by using MS Excel or similar.
Good Luck,

How do I import Map Info Tab files into Spatial for a map of europe?

How do I import Map Info Tab files into Spatial for a map of europe via FME and have oracle spatial draw the map without problems?
So far I've got to the stage where I can import the data, spatially index it (in oracle 9i) and get my SVG (scaleable vector graphics) application to view the map.
The problem is that countries that have more than one polygon (more than one row in the database) do not draw properly.
When I view the Map Info tab file in the FME viewer I can see that the data is fine, but I can also see that some of the polygons used to draw a country are donugts and some aren't.
This seems to cause a problem when I import the data into oracle spatial as I don't know if a row in the table needs to be inserted as an independent SDO_GEOMETRY or if it should form part of a larger SDO_GEOMETRY (as in 2 or more rows make up the polygon shape for a country).
I have a feeling that I'm not using FME correctly, because at the moment I have to import the tab file into Oracle then re-insert the data into a spatially formatted table (one with a spatial index) - I get the impression that FME should do that for me but as I'm new to this I don't really know.
Any Help welcome :|
Tim

Tim,
MapInfo has a free utility called EasyLoader that allows you to upload a table directly to Oracle. EasyLoader creates the geometries and spatial index. You can download it free from http://www.mapinfo.com/products/download.cfm?ProductID=1044

Data Type for Process Flow... PB with Date?

I've got a problem by passing parameters in process flow.
I have a mapping with a parameter DATE_EXEC (data type : DATE) and a default value that is TO_DATE('20/01/2007' , 'dd/mm/yyyy') . My mapping is working good when i launch it.
I have a process flow which contains the mapping. This process has a parameter DATE_EXEC (data type : DATE). I bind the 2 DATE_EXEC. But when i launch my mapping the value is not recognized, I try with :
- TO_DATE('20/01/2007' , 'dd/mm/yyyy')
- 20/01/2007
- 2007.01.20
- 2007-01-20
My question is what are the data type in process flow? They are not ORACLE TYPE.
For example , a parameter in a mapping which is a VARCHAR2 must be input between quotes but if you bind it to a parameter of a process flow which is a STRING (not ORACLE Data type) , you must input it without quotes?
Anybody has some rules about that?
I apologize for my english, i'm a french people.

Here is some information on the literal quote or not quote query and what I think you need to do at the end, hope it helps. Not exactly intuitive...since the flow designer (you) have to know what is a PLSQL object and what is not.
1. Literal = FALSE
When Literal = FALSE is set then the value entered must be a valid PL/SQL expression which is evaluated at the Control Center e.g.
'Hello World!'
22 / 7
2. Literal = TRUE
When Literal = TRUE then the value is dependent on the the type of Activity. If the activity is a PL/SQL object i.e. Mapping or Transformation, then the value is PL/SQL snippet. The critical difference here is that the value is macro substituted into the call for the object. The format of the value is identical to that entered as default value in the Mapping editor. e.g.
'Hello World!'
sysdate()
If the activity type is not a PL/SQL object then the value is language independent. e.g.
Hello World
3.1427571
What you should try......
Check the map activity parameter in your process flow to see if literal is false (an expression), set it to false and then try using your TO_DATE('20/01/2007' , 'dd/mm/yyyy') expression, deploy your flow and execute. Alternatively the user guide defines the DATE type for flow with the format YYYY-MM-DD so you can have the parameter value as '2007-01-20' use literal equal to true and remember and quote your value.
Cheers

How to I get up to date information in Apple Maps?

I just upgraded to Mavericks and was trying Apple Maps, but the maps are showing parks that haven't existed for 10 years, and are missing businesses that have been in my area for over 10 years?
Is there a way to get more up to date information in Apple Maps?

Not sure what you want me to say. Again, the data is as up to date as the providers have it. There's no "cache" or other function you can clear to get newer data. Why the providers, which you can see listed here if you wish:
http://gspa21.ls.apple.com/html/attribution.html
have such out-of-date information I can't begin to guess.
Regards.

Sorry, I'd like to unresolve this. The workaround mentioned is not a solution.
I travel to loads of places by motorcycle, and going off the beaten track is wonderful. Since I upgraded My E6-00 and C7-00 to a Lumia 920, I'm back to allowing the SatNav (phone) to decide where I go. Boring dual carriageways and bypasses are now my natural habitat - bah humbug. Afterall, the phone is in my pocket (safe from weather), headphones in my helmet - I can't constantly look at a map. Having multiple 'favourites' and planning from one to the next isn't workable. Fair enough the Lumia 920 is usable with gloves on (major plus for a biker, come on you marketing people!) but I don't fancy re-routing all the time by the side of a road.
I'm also planning a charity cycle ride over 100s of miles this Summer, and while that can be done in BikeRouteToaster, Google Maps etc, there is no import function into 'HERE' that I can see. It's impossible to plan a route on the device itself. Yes it can route walker (I can't seem to get turn by turn working for that, but nevermind), public transport and car, I have an option to avoid motorways etc, but cycle route planning needs consideration for height metres, unpaved/paved roads (Google StreetView etc used a lot to find a Sustrans route is actually unfit for road bikes) etc. So.. Importing a route planned elsewhere (gpx, kml or something) would be a real alternative, or a workaround. Asking the device to do its own planning from one point to another really isn't workable.
Please make the Nokia's USP an actual USP again?

How to get digital signature for Google Map geocoding V3 in PL/SQL?

Hi, Gurus:
    Could anyone provide me an example about how to generate digital signature for Google Maps service v3 in PL/SQL? We tried to upgrade our program using Google maps service from v2 to v3. We are using PL/SQl on background to send request to Google for geocoding. We found some sample code to register with digital signature, but none of them is based on PL/SQl. Notice I used Google business client ID "gme-XXX" and wallet.
https://developers.google.com/maps/documentation/business/webservices/auth#digital_signatures
Google Maps API - more URL signing samples
Here is my code for V2. I notice in order to get signature, I need to use HMAC-SHA1 algorithm.
procedure Get_Geocoding(P_s_Address in varchar2, P_s_Geocoding out varchar2, P_n_accuracy out number, P_b_success out boolean) is
l_address varchar2(4000);
l_url varchar2(32000);
l_response varchar2(3200);
n_first_comma number;
n_second_comma number;
n_level_length number;
BEGIN
/* TODO implementation required */
l_address:=APEX_UTIL.URL_ENCODE(P_s_Address);
l_address := replace(l_address,' ','+');
l_url := 'http://maps.google.com/maps/geo?q='||l_address||'&'||'output=csv'||'&'||'client=gme-XXX';
l_response := utl_http.request(l_url, APEX_APPLICATION.G_PROXY_SERVER, '/u02/app/oracle/admin/apexsb/wallet', 'XXXXXXXX');

n_second_comma:=instr(l_response,',',1,2);
n_level_length:=n_second_comma-n_first_comma-1;
P_n_accuracy:=0;
if n_level_length>0 then
P_n_accuracy:=to_number(substr(l_response,n_first_comma+1, n_level_length));
end if;
l_response:=substr(l_response,instr(l_response,',',1,2)+1);
--dbms_output.put_line('In function: l_response ='||l_response);
P_s_Geocoding:=l_response;
if (P_s_Geocoding<>'0,0') then
P_b_success:=true;
--dbms_output.put_line('true');
