Perform SUM in Transformation

In the Field Routine, I want to compare the total value of the PO that has been saved in the DSO, agaist the value of the current PO (that I loaded from PSA into this DSO). How should I do this in ABAP? What is the best way to do this in ABAP?

Hi,
First you will have to extract all the data from target DSO in some internal table in start routine after that you can use that internal table for calculation of aggregate value in field routine.
Start routine********
Select PO document
PO item and other fields
from target_dso
into table i_t_dso.
*******Field Routine*******
You can simply loop through this table and get the aggregated value.
data: v_amount type amount.
loop at i_t_dso into wa_dso where po document = Input_document.
v_amount = v_amount + wa_dso-amount.
endloop.
Now you have aggregated value of PO, which you can compare with current PO value which will be input of your field routine.

Poor performance of XSLT-transformation

Hi, everyone
I`ve got report in BI-publisher based on xsl-template.
This template transforms flat xml-file in Excel file and displays the data in the likeness of a cross-tab.
Everything looks fine, but when the input file is larger than 1 MB, then the output file is formed about 10-15 minutes.
However, when the input file is less than 1 MB, I got the output file is less than 1 minute.
How i can see where is the "bottleneck"?
What i can do to improve performance of xslt-transformation?
Thanks

Hi,
Sorry that did not respond sooner.
We have gave the process of 1024 MB memory.
It`s about 4100+ records in result xml.
BIP version is 10.1.3.4 and java - 1.6.
Xsl-template and Xml you can download here
Thank you for reply =)

Perform a bilinear transform without Matlab or MathScript modules

Hi all,
I've been poking around the forums all morning and haven't found what I'm looking for. I've found information, mind you, but it seems I'm not smart enough today to put all the pieces together. So I'm just going to ask, and hope for the best. Maybe someone can point me in the right direction...everything's blurring together at this point.
Is there a relatively straightforward way to perform a bilinear transformation in LabVIEW without the use of either Matlab or MathScript? I don't have access to either one. If there is a built-in LabVIEW function, I'm not finding it.
The MathScript code looks like this:
w3 = 2*pi*f3;
B = [1/w3 1];
w4 = 2*pi*f4;
A = [1/w4^2 1/Q4 1];
[b,a] = bilinear(B,A,fs);
Help?
Thanks!

Solved!
Go to Solution.

Since you are using the transfer function representation you have to do the transformations to and from state space representation and perform the bilinear transform in between. Normally this is hard to do from scratch, but LV has the Characteristic Polynomial.vi built in so it is pretty easy (once you get the formula right).
Statespace <-> Transfer function VIs I have used before so I think they are correct. Bilinear transform was just tossed together using the help from mathworks.

Performance of XSLT transformation

Hello everybody,
I´m trying to do some in-database XML transformations from one XML format to another with a rather complex xsl stylesheet of about 9000 lines of code which performs this transformation. At first I tested the XDK XSLT functionality by simply doing a Transformation over the JAXP API outside the Database. It performed not bad, altough the memory consumption was a little bit higher then Saxon or Xalan. After that I read about the possibilities of in-database transformation, which should consume less memory because of oracle´s xml features like scalable DOM, XML Indexing and Query Rewriting when using object relational or binary storage. So we loaded our testdata into the db (we are using 11gR2 on a test system with Intel Core2Duo @ 3GhZ and 3GB RAM), in different XML storage options (XMLTYPE CLOB, Binary, OR) and tried to do a XSLT transformation on the columns. But it isn´t working.
The db seems not to be able to cope with the transformation although the parser and processor should be the same as the off-database transformation that was working well (or am I wrong?). After half an hour we aborted because the db hadn´t finished the transformation yet (the off-db transformation of this 100KB XML took less then a second). We tried indexing the columns with XMLIndex, didn´t work out, we tried both XMLTYPE´s XMLtransform() and dbms_xslprocessor.processxsl(), same problem, the DB is working and working with no result, after some time we have to terminate. With a simple teststylesheet the transformation is doing fine but our complex stylesheet seems to be the problem.
My question is, why is the xslt performance so poorly with the complex stylesheet and why can I use the XDK Parser and Processor in an off-db transformation very efficiently but when doing the same transformation in the db it´s not working.
Hope you can help me out a little bit I´m really running out of ideas.

Hi,
The db seems not to be able to cope with the transformation although the parser and processor should be the same as the off-database transformation that was working well (or am I wrong?). No, the database built-in XSLT processor (C-based) is not the same as the XDK's Java implementation.
There's also a C XSLT processor available for external transformation and working with compiled stylesheets, it should outperform the Java implementation.
See : http://docs.oracle.com/cd/E11882_01/appdev.112/e23582/adx_c_xslt.htm#i1020191
We tried indexing the columns with XMLIndex, didn´t work out, we tried both XMLTYPE´s XMLtransform() and dbms_xslprocessor.processxsl(), same problem, the DB is working and working with no result, after some time we have to terminate. With a simple teststylesheet the transformation is doing fine but our complex stylesheet seems to be the problem.XMLIndexes won't help at all in this situation.
In my experience so far with the built-in engine, I've seen the best result when the XML document we want transform is stored as binary XML.
I don't know about the scalable DOM (or "lazy" DOM loading) feature described in the documentation, seems it doesn't support complex transformations, much like functional vs. streaming evaluation for XQuery.
Hope you can help me out a little bit I´m really running out of ideas.I'd be interested in a test case if you have the possibility (stylesheet + sample input XML). You can mail me at this address : mb[dot]perso[at]wanadoo[dot]fr
If you can't, could you describe what kind of transformation you're performing and how can I reproduce that behaviour?
Thanks.
Marc.

[9i] poor performance with XMLType.transform

Hello,
I've got a problem with the Oracle function XMLType.transform.
When I try to apply a XSL to a big XML, it is very very slow, and it evens consumes all the CPU, and other users are not able to work until the processing is complete...
So I was wondering if my XSL was corrupted, but it does not seem so, because when i apply it with Internet Explorer (by just double-clicking on the .xml), it is immediately applied. I've also even tried with oraxsl, and the processing is quick and good.
So, i tried to use XDB, but it does not work, maybe I should upgrade to a newer version of XDB?
Please find the ZIP file here :
http://perso.modulonet.fr/~tleoutre/Oracle/samples.zip
Please find in this file :
1) The XSL file k_xsl.xsl
2) The "big" XML file big_xml.xml
Here you can try to apply the XSL on the XML with Internet Explorer : processing is very quick...
3) The batch file transform.bat
Here you can launch it, it calls oraxsl, and produces a result very quickly...
4) The SQL file test_xsl_with_xmltype_transform.sql.
You can try to launch it... First, it applies the same XSL with a little XML, and it's OK... And then, it applies the XSL to the same big XML as in point 1), and then, it takes a lot of time and CPU...
5) The SQL file test_xsl_with_xdb_1.sql ...
On my server, it fails... So I tried to change the XSL in the next point :
6) The SQL file test_xsl_with_xdb_2.sql with a "cleaned" XSL...
And then, it fails with exactly the same problem as in :
TransformerConfigurationException (Unknown expression at EOF: *|/.)
Any help would be greatly appreciated!
Thank you!
P.S. : Sorry for my bad english, I'm a French man :-)

This is what I see...
Your tests are measuring the wrong thing. You are measuring the time to create the sample documents, which is being done very innefficiently, as well
as the time take to do the transform.
Below is the correct way to get mesasurements for each task..
Here's what I see on a PIV 2.4Ghz with 10.2.0.2.0 and 2GB of RAM
Fragments SourceSize TargetSize createSource       Parse     Transform

Of course what this testing really shows is that you've clearly missed the point of performing XSLT transformation inside the database.
The idea behind database based transformation is to optimize XSLT processing by
(1), not having to parse the XML and build a DOM tree before commencing the XSLT processing. In this example this is not possible since the
XML is being created from a CLOB based XMLType, not a schema based XMLType.
(2) Leveraging the Lazily Loaded Virtual DOM when doing sparse transformation ( A Sparse transformation is one where there are large parts of the
source document that are not required to create the target document. Again in this case the XSL requires you to walk all the nodes to generate the
required output.
If is necessary to process all of the nodes in the source document to generate the entire output it probably makes more sense to use a midtier XSL engine.
Here's the code I used to generate the numbers in the above example
BTW in terms of BIG XML we've successully processed 12G documents with Schema Based Storage...So nothing you have hear comes any where our defintion of big.- 1 with Oracle 10g Express on Linux
Also, please remember that 9.2.0.1.0 is not a supported release for any XML DB related features.

Performing SUM with time data

Hi,
is there a way to sum time data as following?
start_time: 10,15 AM
stop_time: 2,35 PM
I expect to do something like:
=(stop_time - start_time)
but this doesn't work.
Thanks anticipately.

Currently we support arithmetic formulas on 12 hour intervals only, i.e., you can perform the following action (Stop_time - Start_time) for Start_time: 1:00AM and Stop_time: 9:00AM. Tables will display 8:00AM as the result. Please make sure you select "date" as the data type for all the columns associated with this operation.
Thanks,
Varun

How to perform an xslt transformation on an xml document dynamically ?

Hi all,
I'd like to perform an xslt tranformation on a dynamically generated xml code. I'm looking for a tag which can by useful for it. The tag should take both xml code and xslt code, passed as String arguments (not as names of xml and xslt files). I tried to use xtags library and jstl:transform tag but it did not work. It worked only with plain xml code passed to x-tag. When I try to perform a transformation on a tag body containing an output text tag, the transformation formats only this tag, not its content.
For example:
<xtags:style xslt="xslName.xsl">
<h:outputText value="#{beanName.stringPropertyName}"/>
</xtags:style>
Thanks in advance

The issue is in the logic f your XSL mapping.
Use the same source XML and use it with XML Spy to debug why it is not working as you want it to.

Performance problem with transformations

Hi,
I'm trying to make an animation with a perspective transformation. In each iterationof the loop, two points are altered.
It works very well, but it is extremely slow. Is there a possibility to speed this up?
while() {
              i++;
               PerspectiveTransform pt = new PerspectiveTransform().getQuadToQuad(
                        10, 10, 200, 0, 0, 190, 200, 200,
                        10-i, 10, 200, 0, 0, 190+1, 200, 200);
                WarpPerspective wp = new WarpPerspective(pt);
                RenderedOp rendOp = createWarpImage(bi, wp);
                RenderedImage renImage = rendOp.createInstance();
                AffineTransform at = new AffineTransform();
                at.scale(0.5, 0.5);
                at.translate(100, 100);
                g2.drawRenderedImage(renImage, at);
        public RenderedOp createWarpImage(RenderedImage image, Warp warp) {
            ParameterBlock paramBlock = new ParameterBlock();
            paramBlock.addSource(image);
            paramBlock.add(warp);
            return JAI.create("warp", paramBlock);
        }

Where is the while loop? direct in your paint method? If yes, here is your problem, because your holding the dispatcher thread. What you need is a render loop:
MyClass implements Runnable
int maxFPS ...
public void run() {
getCurrentMillis()...
doTheBigTransform....
EventQueue.invokeLater(new Runnable() { public void run(){ repaint()... } });
getCurrentMillis() - prevMillis vs time to wait for fps, if > 0
@override
public void paintComponent(Graphics c)
I need more details about your while loop

SignedXml - Signing xml performing custom transform with algorithm "urn://smev-gov-ru/xmldsig/transform"

Hello, fellow colleagues!
I'm trying to sign an XML SOAP request document using SignedXml via detached signature.
In order to pass signature validation I also need to perform two reference transformations. First one is standard XmlDsigExcC14NTransform which I have no problems with. But second one is not provided by Transform class.
This transformation can be performed before passing document to SignedXml but SignedInfo should still contain entry about this transformation in <Transforms> block.
I'm also trying to avoid deriving Transform method.
Is there a way to add a <Transfrom Algorithm="alg"> block with desired transformation algorithm (which by the way is "urn://smev-gov-ru/xmldsig/transform") into SignedInfo without actually performing one and avoid breaking the signature?
So the structure that is to be formed is

Xml validation and transformation in a row: Possible?

Hi.
I'm working on a small tool that uses javax.xml.validation and javax.xml.transform (JDK 6) to perform validation and transformation of xml files in a row.
The problem is, the namespaces and reference to the xml schema required by the validator somehow prevent the transformation from extracting data from the xml file.
Here's the header I use in the xml file:
<tagWhatever
xmlns="http://www.myPlace.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.myPlace.com mySchema.xsd">To sum it up, with the namespace declaration within the xml I can validate but not transform, and without the declaration, I can transform but not validate.
Can anyone help me out witht this one?
Thanks

Exclude NULL values from SUM and AVG calculation

Hi,
I have column in report that contains some NULL values. When i perform SUM,MAX,MIN or AVG calculation on this column the NULL values are treated as '0' and included in calculation. Is there any way to exclude them while calculating aggregate functions?
As a result MIN calculation on values (NULL,0.7,0.5,0.9) gives me output as 0 when it should have been 0.5
Can someone please help ?
Thanks and Regards,
Oliver D'mello

Hi Oliver,
According to your description, you want to ignore the NULL values when you perform aggregation functions.
In this scenario, aggregate functions always ignore the NULL values, because their operation objects are non-null values. So I would like to know if you have assigned “0” for NULL values. I would appreciate it if you could provide some screenshots about
your expressions or reports.
Besides, we have tested in our environment using Min() function. The expression returns the minimum value among the non-null numeric values. Please refer to the screenshots below:
Reference:
Min Function (Report Builder and SSRS)
Aggregate Functions Reference (Report Builder and SSRS)
If you have any question, please feel free to ask.
Best regards,
Qiuyun Yu

BW Back end
Some Tips -
1)Identify long-running extraction processes on the source system. Extraction processes are performed by several extraction jobs running on the source system. The run-time of these jobs affects the performance. Use transaction code SM37 Background Processing Job Management to analyze the run-times of these jobs. If the run-time of data collection jobs lasts for several hours, schedule these jobs to run more frequently. This way, less data is written into update tables for each run and extraction performance increases.
2)Identify high run-times for ABAP code, especially for user exits. The quality of any custom ABAP programs used in data extraction affects the extraction performance. Use transaction code SE30 ABAP/4 Run-time Analysis and then run the analysis for the transaction code RSA3 Extractor Checker. The system then records the activities of the extraction program so you can review them to identify time-consuming activities. Eliminate those long-running activities or substitute them with alternative program logic.
3)Identify expensive SQL statements. If database run-time is high for extraction jobs, use transaction code ST05 Performance Trace. On this screen, select ALEREMOTE user and then select SQL trace to record the SQL statements. Identify the time-consuming sections from the results. If the data-selection times are high on a particular SQL statement, index the DataSource tables to increase the performance of selection (see no. 6 below). While using ST05, make sure that no other extraction job is running with ALEREMOTE user.
4)Balance loads by distributing processes onto different servers if possible. If your site uses more than one BW application server, distribute the extraction processes to different servers using transaction code SM59 Maintain RFC Destination. Load balancing is possible only if the extraction program allows the option
5)Set optimum parameters for data-packet size. Packet size affects the number of data requests to the database. Set the data-packet size to optimum values for an efficient data-extraction mechanism. To find the optimum value, start with a packet size in the range of 50,000 to 100,000 and gradually increase it. At some point, you will reach the threshold at which increasing packet size further does not provide any performance increase. To set the packet size, use transaction code SBIW BW IMG Menu on the source system. To set the data load parameters for flat-file uploads, use transaction code RSCUSTV6 in BW.
6)Build indexes on DataSource tables based on selection criteria. Indexing DataSource tables improves the extraction performance, because it reduces the read times of those tables.
7)Execute collection jobs in parallel. Like the Business Content extractors, generic extractors have a number of collection jobs to retrieve relevant data from DataSource tables. Scheduling these collection jobs to run in parallel reduces the total extraction time, and they can be scheduled via transaction code SM37 in the source system.
8). Break up your data selections for InfoPackages and schedule the portions to run in parallel. This parallel upload mechanism sends different portions of the data to BW at the same time, and as a result the total upload time is reduced. You can schedule InfoPackages in the Administrator Workbench.
You can upload data from a data target (InfoCube and ODS) to another data target within the BW system. While uploading, you can schedule more than one InfoPackage with different selection options in each one. For example, fiscal year or fiscal year period can be used as selection options. Avoid using parallel uploads for high volumes of data if hardware resources are constrained. Each InfoPacket uses one background process (if scheduled to run in the background) or dialog process (if scheduled to run online) of the application server, and too many processes could overwhelm a slow server.
9). Building secondary indexes on the tables for the selection fields optimizes these tables for reading, reducing extraction time. If your selection fields are not key fields on the table, primary indexes are not much of a help when accessing data. In this case it is better to create secondary indexes with selection fields on the associated table using ABAP Dictionary to improve better selection performance.
10)Analyze upload times to the PSA and identify long-running uploads. When you extract the data using PSA method, data is written into PSA tables in the BW system. If your data is on the order of tens of millions, consider partitioning these PSA tables for better performance, but pay attention to the partition sizes. Partitioning PSA tables improves data-load performance because it's faster to insert data into smaller database tables. Partitioning also provides increased performance for maintenance of PSA tables for example, you can delete a portion of data faster. You can set the size of each partition in the PSA parameters screen, in transaction code SPRO or RSCUSTV6, so that BW creates a new partition automatically when a threshold value is reached.
11)Debug any routines in the transfer and update rules and eliminate single selects from the routines. Using single selects in custom ABAP routines for selecting data from database tables reduces performance considerably. It is better to use buffers and array operations. When you use buffers or array operations, the system reads data from the database tables and stores it in the memory for manipulation, improving performance. If you do not use buffers or array operations, the whole reading process is performed on the database with many table accesses, and performance deteriorates. Also, extensive use of library transformations in the ABAP code reduces performance; since these transformations are not compiled in advance, they are carried out during run-time.
12)Before uploading a high volume of transaction data into InfoCubes, activate the number-range buffer for dimension IDs. The number-range buffer is a parameter that identifies the number of sequential dimension IDs stored in the memory. If you increase the number range before high-volume data upload, you reduce the number of reads from the dimension tables and hence increase the upload performance. Do not forget to set the number-range values back to their original values after the upload. Use transaction code SNRO to maintain the number range buffer values for InfoCubes.
13)Drop the indexes before uploading high-volume data into InfoCubes. Regenerate them after the upload. Indexes on InfoCubes are optimized for reading data from the InfoCubes. If the indexes exist during the upload, BW reads the indexes and tries to insert the records according to the indexes, resulting in poor upload performance. You can automate the dropping and regeneration of the indexes through InfoPackage scheduling. You can drop indexes in the Manage InfoCube screen in the Administrator Workbench.
14)IDoc (intermediate document) archiving improves the extraction and loading performance and can be applied on both BW and R/3 systems. In addition to IDoc archiving, data archiving is available for InfoCubes and ODS objects.
Hope it Helps

Transforming XML using XSLT more than once

Hi,
I am trying to transform an XML Document object in Java. However, it requires 2 transforms as each of them is complicated and needs to be generic enough for use by different XML strings. So I have a single XML string and two XSLT files.
Currently, I am using the Java transformer to perform both the transforms one after another. However, I was wondering if there is a function within XSLT or Java that would allow performing the second transform on the result of the first transform without having to resort to multiple calls from within Java.
Thanks a lot.

PL/SQL XSLT transformation problem

I am trying to perform an XSLT transformation inside a PL/SQL procedure using dbms_xslprocessor.processxsl() but I am getting the following error 'LPX-00411: unknown function name encountered'
The transformation XSL contains a java extension to preform some encoding of data and with the template containing the reference to the extension removed the transformation works fine. Does this mean that DBMS_XMLPARSER does not support java extensions in XSL or is it possible I'm just calling the function incorrectly?
I have been testing up to now using oraxsl on the command line which seemed to work fine.
Thanks,
Alan

Alan,
Are you using the right namespace for the class you want to use?

Expanding the appearance of live transform breaks up fill and stroke

Okay, so I never ever use Effect > Distort & Transform > Transform, but with all the hubbub about the stroke scaling bugs in Illustrator CC 2014, I've been fiddling with it lately, and I'm confounded by something: once you perform a "live" transformation of an object, how do you expand the transformation so it's not live anymore, while retaining the integrity of your object? When I use Object > Expand Appearance, it breaks the fill and stroke of the object into two objects. Am I doing it wrong, or is this a bug?
This can't be the normal behavior, since it is impossible to expand the appearance of an ordinary stroked/filled object (the menu item is grayed out).

I can't accept that; the two issues remain:
1) How do you expand/commit the transformation so it's not live anymore, while retaining the integrity of your object? If you can't, that's ridiculous.
2) If this was the normal behavior, then you ought to be able to separate the fill from the stroke on a newly-created shape with Expand Appearance as well, but you can't because it's grayed out.
Furthermore, common sense dictates that the user would rarely—if ever—want their shapes to be exploded like that. Seems more like an egregious oversight than "normal" behavior.
