Hilbert Transform and Error

Hi,
I found this VI on the NI discussion forums whilst trying to determine the phase angle between a voltage and current signal and it has proved a great help.
However, I don't quite understand how the VI works (mainly what the Hilbert function and the error clusters actually do and what effect they have on the VI). Could anyone explain to be how these functions work? I have attached a picture of the VI to clarify my question.
Thanks very much.
Andrew

Hi Andrew,
what the Hilbert transform do: see wikipedia.org or here
error clusters: this function (Error clusters from error code) adds a new error cluster in case the Hilbert transform gives one i.e. the error code is unequal to zero...
You should use error clusters in all your functions as they easily provide means for dataflow programming!

Thanks for your answer.
Make your idea is quite similar to the way I have done. After thoroughly study I have a better understanding of the Hilbert transform and taking the signal envelope.
This is a project completed repair. However, the envelope does not seem to be beautiful.
Hope everyone has comments for issues in order to I can handle more perfect for your project.
Again thanks for comments.

Thanks so much everyone for your suggestions. Iu2019ve tried them all and hereu2019s what I now have:
Anil u2013 Active datasources were included in the original transport. I tried retransporting and got the same error messages.
Voodi u2013 0ACCOUNT_TEXT was resident in the Q system as a 3x datasource. I replicated it as a 70 datasource in D and this is what was transported to Q. It is a 7.0 datasource in Q. I got the same error messages when I tried transporting just the transformations.
Jayaram - 0ACCOUNT is active in the Q system and is currently being used in transformations other than the one Iu2019m trying to import.
Godhuli u2013 I not only re-replicated the datasource in D, I reactivated the transformations and DTPs and resaved the InfoPackages. I tried retransporting with a new transport request and it failed with the same error messages.
Is there anything else anyone can think of?

Hello,
Do you have any routines in the transformation you are trying to transport. Looks like its missing some routines that needs to be transported.
Hope that helps.

How to find the phase difference between two signals using Hilbert transform

hi,
I am new to LabView.... I am trying to find phase difference between two signals. I sucessfuly found out the phase difference between two predefined waves using single tone measurement. .... But I really want to know how can I measure phase difference between two signals( not predefined... ie we don't know the initial conditions) using hilbert transform or any transformation techniques (without using zero cross detection).. I tried by using hilbert transform based on algorithm... bt I am getting error.... plz help me

you could try something similar to this, for each table pair that you want to compare:
SELECT 'TABLE_A has these columns that are not in TABLE_B', DIFF.*
FROM (
        SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
          FROM all_tab_columns
         WHERE table_name = 'TABLE_A'
         MINUS
        SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
          FROM all_tab_columns
         WHERE table_name = 'TABLE_B'
      ) DIFF
UNION
SELECT 'TABLE_B has these columns that are not in TABLE_A', DIFF.*
FROM (
        SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
          FROM all_tab_columns
         WHERE table_name = 'TABLE_B'
         MINUS
        SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
          FROM all_tab_columns
         WHERE table_name = 'TABLE_A'
      ) DIFF;that's assuming, column_name, data_type and data_length are all you want to compare on.

SPM Transformation and Routine are missing in Delivered

Transformation check error

Hi Experts,
I have created transformations in BI7.0 with Start Routine and Transfer Routines.
when i am checking individual routine, checking total transformations, activating transformations and saving transformations also fine without error.
my problem is: when i am checking total transformationsin display mode, it's showing syntax errors in routines.
can u pls tell me my transformations will work properly, or really transformations consist runtime errors.
there is no error in change mode........
thanks,
Venkatesh

Hi,
I think, i have changed the start routine after writing individual routines.
i checked start routine in display mode, no syntax errors found.
pls tell me if i leave the transformations like this, will it work when they run DTP or not?( i cant load now)
Thanks,
Venkatesh

Error while transporting Transformation: Syntax error in Start Routine

Hi Everyone,
I'm facing a strange problem during transporting one of the Business Content cubes from Dev. to Quality.
I'd activated the DSO 'Purchase Order Items (0PUR_O01)' and its entire data flow from the 4 datasources 2LIS_02_CGR, 2LIS_02_SCN, 2LIS_02_SGR, and 2LIS_02_ITM from BC. Then I migrated the Transfer/Update rules to transformations and the DataSources to BI7 DataSource. So far so good. The migration was successful and all the objects were activated.
Now when I transport the same to Quality, the import fails with return code 8 and the error message says:
'Start of the after-import method RS_TRFN_AFTER_IMPORT for object type(s) TRFN (Activation Mode)'
'Start Routine: Syntax error in routine'
I verified that the transformation where the error orrured was the one from InfoSource Z2LIS_02_ITM to DSO 0PUR_O01. I went and checked the start routine and it did indeed have a syntax error:
'In PERFORM or CALL FUNCTION "ROUTINE_9998", the actual parameter SOURCE_PACKAGE" is incompatible with the formal parameter DATA_PACKAGE". '
But when I check in the Dev. system, there is no syntax error for the same routine. Later, I tried to transport only the said transformation by re-activating it in Dev, and again I got the same error.
I have no idea why I'm getting a syntax error in the start routine when there are non in the Dev. system. Also none of the coding is customised, it was only the BC code, migrated to a transformation.
Any suggestions on the steps I could take to transport the transformation to my quality system?
Thanks,
Ram

Hi Ajay, Shanthi, svu and Ray
I do indeed have a start routine in my transformation and it was migrated from a 3.x update rule to a BI 7 transformation routine.
The migration was successful and the Start Routine has NO syntax errors in the start routine in the Dev. system. I only encounter the error while transporting it to the Quality system. I cannot modify the code in the Quality system because it is non-changelable and there is no point in trying to change the code in Dev. because there are no errors over there.
I've also made sure that I've transported all the necessary objects required by the transformations to quality. The routine does not perform a lookup, it simply deletes some records from the data package based on the processkey value (which is itself present in the data package).

Original System for transformations and DataSources

Dear All,
I have imported all DataSources and transformations from DEV box into QAS box. Transports ended without errors and they are working fine.
I have the following questions, when check the Object Directory Entry (RSA1->Extras-> Object directory entry) for transformations and DataSources the Original System is QAS.
Should not the original system be DEV?
Transformations technical names in QAS are not the same as in DEV. Should not they have identical technical names?
Details:
BI70 SAP NetWeaver 2004s
Support Packge 10
Thanks,
Carlos Weffer

Transfornations' technical names change is normal.
Also, when you see the object directory, the sysytem will eb Qa only as you would have converted the source system while transporting.

Inactive transformations and DTPs after running BDLS

Hi Experts
I ran the BDLS job, Restored , Activated and Replicated the S.S.
Some of my transformations and DTPs got inactivated . Does any body have any clue of why this happened.
My observations was when i restored it gave an error message " Error 2 in RFC_VERIFY_DESTINATION " although the S.S check says OK and i am able to do loads and during replication process of S.S it was saying " Function module /SDF/AL_MAP_TRANSID_LOGH does not exist." I am not sure if the above errors/observations have any link to some of Transformations and DTPs getting inactivated while the rest of DTPs are active.
Please advice
Thanks
PK

Prabu,
have you solved this issue?
I am also faceing same issue after BDLS - source system change to BIQ, All DTP's are still assined to OLD-Logical system.
Please let us know how you solved it.
Appreciate your response

Types of DTP , Diff between Standard and Error DTP

Hi experts,
What is DTP , are the Types of DTP , Diff between Standard and Error DTP , how it works in BI 7.0.
I will assign points for your valuable answers.

Hello ,
Data transfer process (DTP) to transfer data within BI from one persistent object to another object, in accordance with certain transformations and filters. In this respect, it replaces the data mart interface and the InfoPackage. As of SAP NetWeaver 7.0, the InfoPackage only loads data to the entry layer of BI (PSA).
The data transfer process makes the transfer processes in the data warehousing layer more transparent. Optimized parallel processing improves the performance of the transfer process (the data transfer process determines the processing mode). You can use the data transfer process to separate delta processes for different targets and you can use filter options between the persistent objects on various levels. For example, you can use filters between a DataStore object and an InfoCube.
Data transfer processes are used for standard data transfer, for real-time data acquisition, and for accessing data directly.
1.Benefit: Data Distributionwithin BI Capabilities (from PSA or InfoProviders to InfoProviders)
2.Improved transparency of staging processes across data warehouselayers (PSA, DWH layer, ODS layer, Architected Data Marts)
3.Improved performance and high scalability
4.Separation of delta mechanism for different data targets: delta capability is controlledby the DTP
5.Enhanced filtering in dataflow
6.Repair modus based on temporary buffers (buffers keep complete set of data)
See these docs for more info

Simple Transformation and RSS feed

OK, I decided to clean up an old program and try it with a Simple Transformation. I created the Simple Transformation and when I "execute" and give it the location of a local copy of the RSS file it returns.
XSLT Tester
Runtime Errors
Reason          : No valid XSLT program supplied
So is this a problem with the ST or is the preview system perhaps missing something? If it's the ST I'll post it otherwise where should I be looking?

I'm going to take a guess, but I'm thinking that the test/debug tool doesn't actually support Simple Transformations, just XSLTs. I couldn't find documentation to support this, but when I looked at the coding of the test/debug application I find that it doesn't use the CALL TRANSFORMATION command - instead it uses the class CL_XSLT_PROCESSOR so that it can trap extra information. In the notes of the program it even states that this is not the correct usage in normal programs and the class is only used here for extra debug information. This class appears to be structured to only support full XSLT and not Simple Transformations.
Although it is pretty easy just to code up your own little test. The key is to include the extra exception handling to get the source position in the ST where the error occurred (very helpful when debugging).
catch cx_st_error into st_err.
   s = st_err->get_text( ).
   st_err->get_st_source_position(
      importing
        prog_name = prog_name
        line = line ).

Proxies - Queueing and Error handling features ???

My understanding is that you can have synchronous and asynchronous proxies. Do proxies have a queueing mechanism, and do they provide reprocessing and error handling features ???
Thanks in advance.

Hi,
The error can happen due to application error, may be incorrect data or or wrong type of data.
Or system error, in case the call to SAP XI is not successful.
Youc an use fault message for the same.
If you want to catch these exceptions in SAP itself and send alert then you can either use standard FM for raising alert.

Risky enable star transformations and trusted Query Rewrites?

Hi,
I need some advice/opinions from someone experienced with large scale
data warehousing.
I'm working on a fairly large data warehouse (around 3 TB), and we're
using Oracle 10.1.0.2.0.
So, I found out about MV's and Star Transformations, and that we're not
using them.
Naturally I decided to try them out in our test environment and I was
more than pleased (actually, I nearly wet my pants) with the potential
performance boost we could get for some of our more critical solutions.
However, I also noticed that the production environment has the
following settings:
star_transformation_enabled = false
query_rewrite_integrity = enforced
...which basically disables all the cool stuff. In the testing
environment I used the following:
star_transformation_enabled = true
query_rewrite_integrity = trusted (to make use of func. dep in
dimensions)
I would like to stand on somewhat solid grounds and increase my
understanding before aproaching our DBA's with the suggestion to change
system global settings :)
Basically, my question(s) are:
1. What are the impact of enabling Star Transformations on a system?
Is there any at all, if no previous solution has been built in a way
to
make use of star transformations?
Or could this change result in fine-tuned queries performing badly
since they
suddenly make use of star transformations?
2. Is "query_rewrite_integrity" used by Oracle for other things besides
Materialized Views?
I'm thinking, if the only thing it's used for is to resolve query
rewrites for MV's, then it's safe to change it, because there are no
such MV's.
Note that I'd like to set it to TRUSTED, in order to make real use
of the dependencies declared with CREATE DIMENSION...
I would be happy to know what you think about this.
Any thoughts, opinions are welcome since this is new grounds for me.
Best Regards
R.

Transport having Transformations & DTPS errored out with RDDEXECL code 12

Hi Friends,
I am importing a Transport request containing Transfromations, DTPs from Dev to QC system and it is erroring out with Code 12 and error is as follows
Program terminated (job: RDDEXECL, no.: 19103500) See job log
When I looked at Job log i can see the folowing details
Job started
Step 001 started (program RDDEXECL, variant , user ID DDIC)
All DB buffers of application server sht014a5 were synchronized
ABAP/4 processor: OBJECTS_OBJREF_NOT_ASSIGNED_NO
Job cancelled
I looked at ST22 and I found the following details
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
     caught in
    procedure "IF_RSBK_TPL_OPTIONAL~SET_LOGSYS" "(METHOD)", nor was it propagated
     by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    You attempted to use a 'NULL' object reference (points to 'nothing')
    access a component.
    An object reference must point to an object (an instance of a class)
    before it can be used to access components.
    Either the reference was never set or it was set to 'NULL' using the
    CLEAR statement.
I am working on SAP NW 2004 S BI 7.0 with support package level at SAPKW70018
Please let me know how to resolve this error.
Thanks
