Integration of Vibration Data

* Friends I am getting Vibration Data through accelerometer in terms of 'g'. the requirement is like I should diplay the acceleration in mm/s^2, Velocity in mm/Sec and displacement in mm. * Another thing is I have an Acoustic Data which is in terms of Pa. I need to show it in decibels. Though I have tried with single and double integration of vibration data with SVL Integration.vi but am nt sure wether the readings will simply be transformed to mm/sec jus by selecting the unit in the input terminal. do i need to change the original Data or do some mathematics? waitin 4 ur replies... Thanks

If you are using the scale to engineering units VI on the data from the DAQmx task, then your data is originally represented in mm/s^2 and pa. The Sound and Vibration integration functions manages the units and converts them with the appropriate math the displacement or decibels. The units output of the integration VI will confirm the VI has done the work. There should be not extra mathematics, just run the waveforms thru the scale to engineering units VI and then the integration VI.

[Integration Engine Configuration Data] Error: No access to system landscap

Hi all,
When configuring Integration Engine Data (To go to 'Integration Engine Configuration Data' screen: Tcode: SXMB_ADM -> Choose: Integration Engine Configuration -> F8), we want to load Configuration from System Lanscape by choose F6, an error occur with message as below:
No access to system landscap
So that we can't load configuration from our System Landscape.
We have correctly configured other below:
     - We use http port for corresponding Integration Server.
     - Business System with role 'Integration Server' created correctly in SLD.
     - T-code SLDCHECK is all OK.
     - T-code SXI_CACHE is all OK.
Anyone can please help me correct this error ?
Point will be reward for any valuable answer,
Thanks a lot,

How to present vibration data in G vs Hz Graph?

Hi all,
I'm using NI9233 to acquire the vibration data in X,Y & Z direction. I need to present these data in G vs Hz Graph. From the graph I need to pick up the value of the highest peak value in G and Hz. Btw, I also need to save the graph waveform every time I run my VI for different direction (X,Y,Z). Anyone can help me solving this problem?
Thank you.

Hi Ivan99,
You can create an acceleration task in Measurement and Automation Explorer (MAX) for your NI 9233 and scale it appropriately
to get your data in Gs. To create the task, open up MAX and right click Data Neighborhood then select Create New » NI DAQmx Task » Acquire Signal» Analog Input » Acceleration. Assuming you are using LabVIEW, you can use an Array Max & Min VI to extract the maximum value in a given data set. When you say you want to save the waveform every time you run your VI, would you like to save your data or the graph itself.
If you have never used DAQmx or LabVIEW to acquire data, I would recommend the Complete DAQ Tutorial as a starting point. I hope this helps.

Integrating Flat File data to LDAP Directory using sunopsis driver

Hello
I need to import data from a csv file into a LDAP Directory.
In order to acheive this, i used Demo physical and logical File data server (called FILE_GENERIC) and set up a new LDAP data server using tutorial "Oracle Data Integrator Driver for LDAP - User's Manual".
I can manually see and update data on both file and LDAP datastores.
The fact is that i cannot manage to import/update data from the file to the LDAP directory through a dedicated interface.
The issue do, i think, come from the PK/FK used by sunopsis relational model to represent the directory.
LDAP DN is represented by a set of two table representing in my example the organizational units in one hand and the persons in the other hands, linking them through FK in persons to auto-generated PK in organization units. My person table also have a auto generated PK. All the directory datastore tables have been reversed through ODI.
In my interface, i always use my cn as update key.
I first tried not to map the person PK in the interface, letting the driver generating it for me (or mapping a null PK). I then catch in operator a message like: " null : java.sql.SQLException: Try to insert null into a non-nullable column".
Anyway, the first row is created in the directory and a new PK is given into ODI datastore. Curiously, this is not as i would presume the last PK value + 1.
There are some kinds of gaps in the ID sequences.
I even tried checking the "tolerated error" into the IKM step called "Insert new row". I'm using IKM shipped with ODI :"IKM SQL Incremental Update". The sequence is finished in operator but due, i guess, to the catched error, the other rows are not processed. (Anyway i shouldn't have to tolerate errors)
I tried after to put not used custom PK values into my file, then map the PK column to the LDAP datastore PK column without much success: Only one row is processed. Futhermore, the id of the PK in the datastore is different of the one I put in the file.
I finally tried to generate PK values through SQL instructions by creating new steps in the IKM modul but that did not worked much.
I really do not see any other ideas to either have the driver construct new PK at insert/update or to make him ignore the null PK problem and process all the rows.
If anyone do have an idea about it, please share...
Greetings,
Adrien

Hi,
I am facing an issue who is probably the same.
using ODI 10.1.3.5, I can't insert new rows into my openLDAP.
One of the point I see is that the execution take the LDAP server for staging area and want to create I$ table into it, so the data are already imported into the ldap Server.
thanks for any help.

SRM Integration with HR data

Hello SDN community,
Our company is struggling right now, because we are not coming up with very good options for an SRM implementation.
I have tried to read some of the posts regarding SRM and OM integration, but I have zero experience with SRM.
I understand that SAP offers a number of ways for an HR system to mirror data either through ALE or other methods to a stand-alone SRM system.
We currently have a full OM implementation in our HR system, of org units, positions, and employees. The SRM team is struggling though because we have a very global and functional org structure, meaning for an org unit like IT operations, we have positions from 5 different countries. Because of this, HR does not maintain company code at the organizational unit. We only maintain the company code at the position level in HRP1008.
Also, from my understanding when an organizational unit in SRM is linked to a company code it does it in a completely separate infotype (not hrp1008), but an infotype called 'function'. This infotype does not even appear to be available in our HR system, which does not have SRM installed.
Also, we do not have a single purchasing organization, so the desire is to have purchasers across our organization and for the approval process to follow the HR line manager hierachy and not a separate standalone Org maintained to support purchasing.
So based on this information, can someone please provide a functional description of how a standalone ECC 6.0 system with only HR, would integrate OM data to a separate system with SRM installed?
How would this integration overcome the problem of the HR system not having the SRM OM infotypes?
How would we overcome the problem of the HR Org structure not representing a company code structure, since company codes are more granular for us at the position level?
Please direct me to any relevant documentation, as I am not finding it easy to get these questions answered on my own.
Thank You,
Michael

Hi Michael,
In our company we have implemented classic scenario (SRM 5.5). We are also using the organizational structure, which is transported and updated from HR system. This transportation is done with ALE distribution model (detailed information about this can be received from BASIS consultant).
In my opinion it is not necessary company code, purchasing group and purchasing organizations to be maintained in Hr structure. Once the structure is transported in SRM, you can maintain them in SRM.
I will try briefly to summaries you the integration process.
I presume that you have already establish the RFC connections between the two systems (SRM and HR), you have maintained all integration switches in both systems, and you have maintained BP number ranges for the position assignment and organizational units (in this case the number range is external for SRM and it has to be the same as in HR system).
It is very important, to maintain the address data (such as country, city and post code) of the organizational units, before transportation of the structure from the HR system to SRM.
Relationships between Business Partner numbers of employees and org units and Central Person numbers have to be checked in transaction "Users_Gen". No errors should exist in this report.
Once the structure is transported, you have to assign the company code, purchasing organization and purchasing groups in SRM.
We are using two company codes and two purchasing organization. We have made a special development which is mapping the purchasing groups to the different Purchasing organizations (all purchasing groups are assigned to one central Purchasing organization, and after that a mapping is done in a separate table to the other Purchasing organization).
I have created manually organizational units, which represents the company code, purchasing organization and purchasing groups.
If you do so, you have to assign their functions (company, purchasing group or purchasing organization), in the FUNCTION TAB in transaction PPOMA_BBP and the responsibility of each purchasing group in the responsibility tab.
Please have in mind that the persons responsible for maintaining the organizational structure in HR system, have to be notified that you are using manually created organizational units. If the update of the SRM structure is set to be automatically from the HR structure, your units can be deleted.
After that you should maintain the attributes at organizational unit or at position level for the different users.
For example, I have maintained company code at a position level because, in one department, representing one org unit, I have users creating shopping carts for different company codes.
Hope it is clearer for you now!

No Connection to Integration Builder (Local Data)

Hi All,
I am having problems in proxy configuration. When i run sproxy it says no configuration data found. I have done all the settings required for the same(think so).
I have created LCRSAPRFC, SAPSLDAPI tcp/ip connection in the business system(R/3) and also a http connection (XI_INTEGRATIONSERVER) which im mentioning in the integration engine configuration(SXMB_ADM) as http://xi_integrationserver.I have selected the role as Application System.
SPROX_CHECK_IFR_ADDRESS & SPROX_CHECK_HTTP_COMMUNICATION works fine.
But problem with SPROX_CHECK_IFR_RESPONSE & SPROX_CHECK_IFR_CONNECTION.
This report SPROX_CHECK_IFR_RESPONSE says...
says HTTP error (return code 400, message "ICM_HTTP_CONNECTION_FAILED".
When i check the http connection XI_INTEGRATIONSERVER.
It also gives the same error.
These are the settings which i have done in the RFC.
Target Host : xiserver
Port : 8000
Path Prefix : /sap/xi/engine?type=entry
In the logon tab im specified
xiappluser n the password.
LCRSAPRFC, SAPSLDAPI Connections works fine in the Business System (R/3)
I have also tried this link in internet explorer..
http://xiserver:8000/sap/xi/engine?type=entry
It then asks for login id n password ..
n it doesnt accept anyuser..be it xisuper.xiappluser.xirwbuser..xiisuser..
Can anyone also please letme know which user id do i need to use or which role do we need.
Please lemme know where im going wrong.
Cheers,
Sumit

Hi ,
In the technical settings i gave the IPAddress inplace of the host name. Now the connection works.
But the thing is that when i click on test Connection it asks for the username,password,client. Even though i have mentioned those in the logon parameters.
I checked by using xisuper but it still asks for username and password.
Again i checked using the report SPROX_CHECK_IFR_RESPONSE. It still gives the same error.
Maybe cause it isnt getting the username & password.

Integrating Third Party Data with BI Apps

Hi,
I have had a couple of inquiries from customers interested in BI Applications, but who want to integrate their reporting with data from other operational systems.
My question is: what is our recommended best practice for this scenario. Would we recommend customers to maintain two separate data warehouses with a single BI Server pointing to them and do the 'integration' at the enterprise model layer; or would we recommend the incorporation of their operational data into the BI Applications DW?
Obviously there are pros and cons for each and I would be interested to hear your views on these, understand what the implications are, and understand what our recommend approach is.
Thanks,
JOHN

I am not sure of any standard integration programs specific to recruitment, but through customization we can integrate third party rectt systems like People click, HRP etc.
Develop inbound programs with ALE-IDOC system to transfer the data to Rectt tables.
The switch will control activation of integration between the systems.
If this helps, pl do reward.
Thanks

Integration Builder - runtime data cache - Error when creating cache list

All,
When I go into the Integration Builder --> Administration --> Runtime tab --> Data Cache
I get a message saying "Error when creating cache list".
All cache areas look ok and I do not see any other error.
Also, RFC INTEGRATION_DIRECTORY_HMI looks good.
Please advise.
Thanks a lot.

Hi,
Use transaction SXI_CACHE to update the Integration Directory cache. Alternatively, you can use the following URLs to update the CPA cache. Use XIDIRUSER to refresh the cache.
For complete cache refresh u2013 http://<hostname>:<port>/CPACache/refresh?mode=full
For delta cache refresh u2013 http://<hostname>:<port>/CPACache/refresh?mode=delta
If this does not solve the issue, check transaction SLDCHECK to ensure that connection to SLD is available. If the connection fails, check the configuration in the transaction SLDAPICUST. Make sure that the password maintained is correct and the maintained service user is not locked.
Now in the Integration Repository go to Environment u2192 Clear SLD Data Cache. Also go to Integration Directoy and clear the cache using menu Environment u2192 Clear SLD Data Cache.
Open the XI Start Page and click on Administration. On the Repository tab, choose Cache Overview. Refresh the cache using the buttons/icons on the right. Use XIDIRUSER to refresh the cache. Carry out cache refresh in the same way on the Directory and Runtime tabs.
regards,
ganesh.

DI Integrator XI and Data Service Designer

Hi all
I am playing with DI XI (11.7) now, but very soon we would have Data Service Designer (new version of DI which is called Data Service Designer). I'm just wondering what the difference is between DI Integrator 11.7 and Data Service Designer. The interface and object types are very different and a big surprise for me? Or I might ask what's new in Data Service Designer?
Thanks for your help.

You will be very familiar with DataServices Designer. You will find more transforms - the data quality transforms - and a few menu items, flags etc. But really, DataServices is just a name change. For DQ customers things changed a lot.

Oracle Data Services Integrator Vs Oracle Data Integrator

Hi All,
I have an ODSI Project in ODSI 10g R3. I want to migrate it to 11G as we are migrating from 10G to 11G in all other components.
Is there any upgrade version of ODSI available? Or
What is ODI(Oracle Data Integrator)? Can I use this?
Please help me.
Regards.
Nataraj R.

Hi,
ODSI will only work on WLS 10.3.0, not the latest release WLS 10.3.6 (also known as 11gR1 PS5). This is usually not an issue as ODSI typically is not collocated with other WLS applications on the same machine; you can view an ODSI+WLS cluster as a black box.
We are working on a new ODSI release, but we have not published a release date or the version it will be.
ODI is significantly different architecturally than ODSI; ODI moves data to a consolidated target database, while ODSI federates access to distributed sources without an additional database. You can search online for federation vs. consolidation to get a comparison of these two techniques. Depending on your use case and requirements ODI might be an option for you.

Character integrity issue after data conversion in database/JDBC

Hi
I am using oracle 9i with the following NLS setting:
NLS_LANGUAGE :AMERICANS
NLS_CHARACTERSET : UTF8
NLS_NCHAR_CHARACTERSET :AL16UTF16
I am running on Linux with this as my environment Language:
Lang: en_US.UTF8
I am sending hindi characters in XML file (UTF-8 encoding) to my java application to be stored in the database. In my xml file, I give this encoding (ignore the double quotes, reason for putting in the quotes so that the browser will not interpret it)
"&#x928";"&#x92E";"&#x938";"&#x94D";"&#x924";"&#x947"
But the characters appeared unreadable in the database. When I use Select DUMP to check the characters encoding:
Typ=1 Len=12 CharacterSet=UTF8: 0,28,0,2e,0,38,0,4d,0,24,0,47
When I retrieve data from the database via my application, the weird characters will appear.
However, if i manually input the hindi characters into the column of the table, then the Hindi characters appear correctly. When I do a DUMP to check, this is what I get:
Typ=1 Len=12 CharacterSet=UTF8: 9,28,9,2e,9,38,9,4d,9,24,9,47
When I check the unicode chart here http://www.unicode.org/charts/PDF/U0900.pdf, the second DUMP result is correct. When I retrieve data from the database via my application, the correct hindi string appear.
I understand that in Java the encoding is in UTF-16 and Oracle JDBC will convert from UTF-16 to UTF-8 before storing in my database and vice versa. The thing that puzzles me is why correct hindi string appears on my web interface when that the same conversion is used to extract the data from the database. At first I suspect it is the conversion problem in JDBC when the UTF-16 characters get truncated to UTF-8 when I try to store the data to database. But when good data is stored in the database, the extraction seems to be correct albeit that it is going through the same conversion.
I read from several threads of this forum and also the Oracle Globalization Support article but I cannot find an answer to my question.
Can anyone help? Thanks.

A couple of checkpoints for you:
1. When you load the XML from SXMB_MONI in the test tab of message mapping it turns red..this means the constructed XML (from CC content conversion) doesnt match the one (XSD) defined in your ESR/IR. In this case you have to check again thoroughly the file content conversion fields values/field length in the sender Communication chaneel.
2. Once you rectify the error above then you can test the mapping in ESR message mapping.

E Rec integration issue while data transfer

Hi Experts,
In E Recruitment we are facing an issue that when education is getting transferred from E Rec to PA then education is not getting transferred correctly.
The issue is because in E Rec we are using table T77RCF_DEGREE & in PA we are using Table T518a. Challenge is coming in their synchronization.
Please suggest if any workaround is possible.

Puneet

Hi Puneet,
Usually the 'standard way' to execute the syncronization is through the indicated steps in the following link:
SAP Library - Talent Management and Talent Development
This scenario must be recommended to your customer if its using talent management in its HCM system and its in the correct version. Otherwise, if the customer still requires the sync to PA infotypes, I see the following walkarounds: (Depending your scenario, the technology you're using and the moment in which you need to sync the data, if you can provide more detail in this points we can get the best solution)
- Implement a custom RFC with all the logic to read/write/convert the information between infotypes
- Use PI to convert/translate the information
- Modify the logic of the synchronization reports mentioned in the link above.
Hope this helps.
Regards.
