Best Practice for Initial Load Data

Dear Experts,
I would like to know the best practices or factors to be concerned when performing initial load
For example,
1) requirement from business stakeholders for data analysis
2) age of data to meet tactical reproting
3) data dependency crossing sap modules
4) Is there any best practice for loading master data?

Best Practice for Initial Load

Hello,
what is the best way of doing the initial load? is there a best practice somwhere that tells you what should be imported first?
I want to understand the order ex,
1. load Lookups,
2. Hierarchies,
3. taxonomy and attributes
last the main table
etc...
I dont understand the logic.
Thanks in advance

Hi Ario,
If you follow any SAP Standard business content for MDM Repositories like e.g. Material.
https://websmp130.sap-ag.de/sap/support/notes/1355137
In the SAP Note attachments, you will get MDM71_Material_Content.pdf
You will see Import of reference Data(look up table's data) 1st(step6) before import of Master data(step7).
During Import of Reference Data(look up data), Please follow the Import Sequence by using Processing level 0,1,2 etc.
Which take care of filling look up flat tables first then filling Hierarchies tables etc.
After that if you are maintaining Taxonomy, You need to fill taxonomy table in Taxonomy mode of Data Manager, in the sequence (Categories, Attributes, Linkage between Attributes and Categories and lastly Attribute Values)
After this I mean populating Reference data you need to populate Main table records along with tuples table data since now in MDM 7.1 Tuple has been replaced by Qualified table for most of the Master's but if you are still maintaining Qualified table you can import Mani table data along with Qualified table in a single step. Otherwise for Qualified table you can alos use this approach of populating Non-qualifeirs to Qualified table first before importing main table and then importing Main table data along with Qualifier's field of Qualified table.
This above entire process for exporting data from SAP R/3 system to MDM. If you are importing data into MDM from legacy system (Non-Sap systems too), Approach should be remain same Populating Lookup tables data and lastly main table data.
I dont understand the logic.
The logic is simple in your main table you have fields which are look up to Reference tables( e.g. field in main table which are look up to Lookup flat tables like Countries, Currencies etc, field in main table which is lookup to Hierarchy/Taxonomy table etc). So, if these values are not populated firstly, so during your Main table import you will have incomplete data for all of these fields from main table which are look up to some other tables as values in your lookup table you haven't populated before Main table import.
Kindly revert if you still have any doubts.

Best practices for initial data loads to MDM

Hi,
We need to load more than 300000 vendors from SAP into MDM production repository. Import server might take days to load that much if no error occurs.
Are there any best practices for initial loads to MDM available? What considerations must be made while doing the initial loads.
Harsha

Hello Harsh
With SP05 patch1 there is a file aggregation functionality in the import port. Is is supposed to optimize the import performance.
BTW, give me your mail address and I will send you an idoc packaging paper for MDM.

Best practice for initializing objects in a JSF backing bean?

Hi,
What is the best practice for initializing some objects in the JSF to-page backing bean before the to-page is displayed for the first time? The initialization would vary and depend upon a command link in the from-page.

Best practice for putting binary data on the NMR

Hi,
We're creating a component that will consume messages off the NMR, encode them, and subsequently put them back on the NMR. What's the best practice for sending binary data over the NMR?
1. setContent()?
2. addAttachment()?
3. setProperty()?
If NormailzedMessage.setContent() is the desired approach, then how can you accomplish that?
Thanks,
Bruce

setContent() is used only for XML messages. The recommended way to accommodate binary data is to use addAttachment().

Best Practice for disparately sized data

2 questions in about 20 minutes!
We have a cache, which holds approx 80K objects, which expired after 24 hours. It's a rolling population, so the number of objects is fairly static. We're over a 64 node cluster, high units set, giving ample space. But.....the data has a wide size range, from a few bytes, to 30Mb, and everywhere in between. This causes some very hot nodes.
Is there a best practice for handling a wide range of object size in a single cache, or can we do anything on input to spread the load more evenly?
Or does none of this make any sense at all?
Cheers
A

AHi A,
It depends... if there is a relationship between keys and sizes, e.g. if this or that part of the key means that the size of the value will be big, then you can implement a key partitioning strategy possibly together with keyassociation on the key in a way that it will evenly spread the large entries across the partitions (and have enough partitions).
Unfortunately you would likely not get a totally even distribution across nodes because of having fairly small amount of entries compared to the square of the number of nodes (btw, which version of Coherence are you using?)...

Best Practice for Using Static Data in PDPs or Project Plan

Hi There,
I want to make custom reports using PDPs & Project Plan data.
What is the Best Practice for using "Static/Random Data" (which is not available in MS Project 2013 columns) in PDPs & MS Project 2013?

Best practices for submitting CF data to an AJAX page?

Hi everyone,
I've got a project I'm working on for work and have hit a
little problem.
I am extracting data from my database and then after each
piece of data (just numbers, usually 10 chunks of numbers), I tack
a "|" onto the end of each number. Then, I output the data to the
page. Back on my AJAX enabled page, I get the "responseText" from
that page, and then split it up using javascript and the
pre-inserted "|".
This seems to work fine, but it is quite a bit more messy.
Also, It would really, really be nice to be able to do sorting and
various other operations on the data with javascript instead of
having to rely on CF's icky code logic.
Can someone please enlighten me as to best practices for this
type of thing? I get the suspicion that I'll probably be using XML
somehow, but I'd your opinion.
Thanks!

Best practice for storing/loading medium to large amounts of data

I just have a quick question regarding the best medium to store a certain amount of data. Currently in my application I have a Dictionary<char,int> that I've created, that I subsequently populate with hard-coded static values.
There are about 30 items in this Dictionary, so this isn't presented as much of a problem, even though it does make the code slightly more difficult to read, although I will be adding more data structures in the future with a similar number of items.
I'm not sure whether it's best practice to hard-code these values in, so my question is, is there a better way to store this information, retrieve and load it at run-time?

You could use one of the following methods:
Use the application.config file. Upside is that it is easy to maintain. Downside is a user could edit it manually as its just an xml file.
You could use a settings file. You can specify where the setting file is persisted including under the user's profile or the application. You could serialize/deserialize your settings to a section in the settings. See
this MSDN help section
on details abut the settings.
Create a .txt, .json, or .xml file (depending on the format you will be deserializing your data) in your project and have it be copied to the output path with each build. The upside is that you could push out new versions in the future of the file without
having to re-compile your application. Downside is that it could be altered if the user has O/S permissions to that directory.
If you really do not want anyone to access it and are thinking of pushing out a new application version every time something changes you could create a .txt, .json, .xml file (depending on the format you will be deserializing your data) just like the previous
step but this time mark it as an embedded resource in your project (you can do this in the properties of the file in visual studio). It will essentially get compiled in your application. Content retrieval is outlined in
this how to from Microsoft and then you just deserialize the retrieved content the same as the previous step.
As far as formats of your data. I recommend you use either XML or JSON or a text file if its just a flat list of items (ie. list of strings). Personally I find JSON much easier to read compared to XML and change and there are plenty of supported serializers
out there. XML is great too if you need to be strict as to what the schema is.

Best practice for lazy-loading collection once but making sure it's there?

I'm confused on the best practice to handle the 'setup' of a form, where I need a remote call to take place just once for the form, but I also need to make use of this collection for a combobox that will change when different rows in the datagrid or clicked. Easier if I just explain...
You click on a row in a datagrid to edit an object (for this example let's say it's an "Employee")
The form you go to needs to have a collection of "Department" objects loaded by a remote call. This collection of departments only should happen once, since it's not common for them to change. The collection of departments is used to populate a form combobox.
You need to figure out which department of the comboBox is the selectedIndex by iterating over the departments and finding the one that matches the employee.department.id
Individually, I know how I can do each of the above, but due to the asynch nature of Flex, I'm having trouble setting up things. Here are some issues...
My initial thought was just put the loading of the departments in an init() method on the employeeForm which would load as creationComplete() event on the form. Then, on the grid component page when the event handler for clicking on a row was fired, I call a setup() method on my employeeForm which will figure out which selectedIndex to set on the combobox by looking at the departments.
The problem is the resultHandler for the departments load might not have returned (so the departments might not be there when 'setUp' is called), yet I can't put my business logic to determine the correct combobox in the departmentResultHandler since that would mean I'd always have to fire the call to the remote server object every time which I don't want.
I have to be missing a simple best practice? Suggestions welcome.

Hi there rickcr
This is pretty rough and you'll need to do some tidying up but have a look below.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Script>
        <![CDATA[
            import mx.controls.Alert;
            import mx.collections.ArrayCollection;
            private var comboData:ArrayCollection;
            private function setUp():void {
                if (comboData) {
                    Alert.show('Data Is Present')
                    populateForm()
                } else {
                    Alert.show('Data Not')
                    getData();
            private function getData():void {
                comboData = new ArrayCollection();
                // On the result of this call the setUp again
            private function populateForm():void {
                // populate your form
        ]]>
    </mx:Script>
    <mx:TabNavigator left="50" right="638" top="50" bottom="413" minWidth="500" minHeight="500">
        <mx:Canvas label="Tab 1" width="100%" height="100%">
        </mx:Canvas>
        <mx:Canvas label="Tab 2" width="100%" height="100%" show="setUp()">
        </mx:Canvas>
    </mx:TabNavigator>
</mx:Application>
I think this example is kind of showing what you want. When you first click tab 2 there is no data. When you click tab 2 again there is. The data for your combo is going to be stored in comboData. When the component first gets created the comboData is not instansiated, just decalred. This allows you to say
if (comboData)
This means if the variable has your data in it you can populate the form. At first it doesn't so on the else condition you can call your data, and then on the result of your data coming back you can say
comboData = new ArrayCollection(), put the data in it and recall the setUp procedure again. This time comboData is populayed and exists so it will run the populate form method and you can decide which selected Item to set.
If this is on a bigger scale you'll want to look into creating a proper manager class to handle this, but this demo simple shows you can test to see if the data is tthere.
Hope it helps and gives you some ideas.

Best Practice for Flat File Data Uploaded by Users

Hi,
I have the following scenario:
1.     Users would like to upload data from flat file and subsequently view their reports.
2.     SAP BW support team would not be involved in data upload process.
3.     Users would not go to RSA1 and use InfoPackages & DTPs. Hence, another mechanism for data upload is required.
4.     Users consists of two group, external and internal users. External users would not have access to SAP system. However, access via a portal is acceptable.
What are the best practice we should adopt for this scenario?
Thanks!

Hi,
I can share what we do in our project.
We get the files from the WEB to the Application Server in path which is for this process.The file placed in the server has a naming convention based on ur project,u can name it.Everyday the same name file is placed in the server with different data.The path in the infopackage is fixed to that location in the server.After this the process chain trigers and loads the data from that particular path which is fixed in the application server.After the load completes,a copy of file is taken as back up and deleted from that path.
So this happens everyday.

Best practice for exposing internal data to external world?

Currently we have our Internet server sitting in our corporate DMZ taking website and web service requests from the outside world. Class libraries with compiled connection strings exist on that server. That server then has a connection through
the firewall to the database server. I'm told that this is no longer the secure/recommended best practice.
I'm told to consider having that Internet server make requests of not the database server, but rather a layer in between (application server, intranet server, whatever) that has those same Web UI methods exposed.. and then THAT server (being inside the firewall)
connects to the database server.
Is this the current recommended best practice to have external users interact with internal data? It seems like lots of hoops -- outside person app queries Web UI methods on Internet server which in-turn queries same method (duplicated) on Intranet
server which then talks to the database.
I'm just trying to determine the simples practice, but also what is appropriately secure for our ASP.NET applications and services.
Thanks.

IMO this has little to do with SOA and all about DMZs. What you're are trying to stop is the same comm protocol accessing the database as accessed the web site. As long as you fulfil that then great. WCF can help here because it helps with configuring
the transport of calls. Another mechanism is to use identities but IMO it's easier to use firewalls and transports.

Best practices for using .load() and .unload() in regards to memory usage...

Hi,
I'm struggling to understand this, so I'm hoping someone can explain how to further enhance the functionality of my simple unload function, or maybe just point out some best practices in unloading external content.
The scenario is that I'm loading and unloading external swfs into my movie(many, many times over) In order to load my external content, I am doing the following:
Declare global loader:
var assetLdr:Loader = new Loader();
Load the content using this function:
function loadAsset(evt:String):void{
var assetName:String = evt;
if (assetName != null){
assetLdr = new Loader();
var assetURL:String = assetName;
var assetURLReq:URLRequest = new URLRequest(assetURL);
assetLdr.load(assetURLReq);
assetLdr.contentLoaderInfo.addEventListener( Event.INIT , loaded)
assetLdr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, displayAssetLoaderProgress);
function loaded(event:Event):void {
   var targetLoader:Loader = Loader(event.target.loader);
   assetWindow.addChild(targetLoader);
Unload the content using this function:
function unloadAsset(evt:Loader) {
trace("UNLOADED!");
evt.unload();
Do the unload by calling the function via:
unloadAsset(assetLdr)
This all seems to work pretty well, but at the same time I am suspicious that the content is not truly unloaded, and some reminents of my previously loaded content is still consuming memory. Per my load and unload function, can anyone suggest any tips, tricks or pointers on what to add to my unload function to reallocate the consumed memory better than how I'm doing it right now, or how to make this function more efficient at clearing the memory?
Thanks,
~Chipleh

Since you use a single variable for loader, from GC standpoint the only thing you can add is unloadAndStop().
Besides that, your code has several inefficiencies.
First, you add listeners AFTER you call load() method. Given asynchronous character of loading process, especially on the web, you should always call load() AFTER all the listeners are added, otherwise you subject yourself to unpredictable results and bud that are difficult to find.
Second, nested function are evil. Try to NEVER use nested functions. Nested functions may be easily the cause for memory management problems.
Third, your should strive to name variables in a manner that your code is readable. For whatever reason you name functions parameters evt although a better way to would be to name them to have something that is descriptive of a parameter.
And, please, when you post the code, indent it so that other people have easier time to go through it.
With that said, your code should look something like that:
function loadAsset(assetName:String):void{
     if (assetName) {
          assetLdr = new Loader();
          assetLdr.contentLoaderInfo.addEventListener(Event.INIT , loaded);
          assetLdr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, displayAssetLoaderProgress);
          // load() method MUST BE CALLED AFTER listeners are added
          assetLdr.load(new URLRequest(assetURL));
// function should be outside of other function.
function loaded(e:Event):void {
     var targetLoader:Loader = Loader(event.target.loader);
     assetWindow.addChild(targetLoader);
function unloadAsset(loader:Loader) {
     trace("UNLOADED!");
     loader.unload();
     loader.unloadAndStop();

Best method for initial upload data into CRM

Hey guys,
could someone tell me what is the best and fastest method to upload a mass of data (11 mio. BPs) to CRM? Now i am not sure. I thought you have to do that through the CRM middleware. Now i read you can do this also via IDOC. Which method should i use to do this? What about LSMW?
regards,
Ming

Hello Ming,
Could you tell us where is the Mass Data of BP located?
Are you trying to upload the data from R/3 to CRM? or from legacy systems?
If its from legacy or non-R/3 systems then LSMW is the best approach.
But if its from R/3 to CRM, then better approach would be via MW since once initial load is performed using txn:R3AS,
subsequent delta changes would flow down automatically to CRM.
Hope this helps!
Best Regards,
Shanthala Kudva.
