Model segregation strategy question

Hello,
we are planning to build a system for test data managment using Toplink and RCP as frontend.
E.g. we have one module responsible for persons used overall. Another module will be responsible about all our units under test (e.g. engines, injection valves). The next one for sensor instrumentation definition etc.
Currently we have one large data model, which we describe in one XML file. But we think about splitting this into several separate ones corresponding to the plug-ins we have.
This would mean that we would have a session with a lot of projects.
I think from the maintenance point this would be easier to handle than a large project. But what would be with complex queries all over the DB tables. Would this then be possible?
Will the different projects in a session be available "as one project" for such queries?
What would be the better approach for something like this? I did not really find something about such architectural design questions in the manual.
Regards
Robert

Hello,
Just to be sure of the details, you are saying that all these different projects will be combined into a single session using the same database etc. If so, then they will pretty much be a single project - all the descriptors from the various independent projects will need to be combined into a single project before the session logs in. Depending on how independent they are or need to be, you can also then use customizers or loggin events to map relationships that might need to exist between descriptors in different projects that might not have been mapped. Since this is a single project/session, there is no problem with queries. The only problems that might arise are if two projects use the same class using a different descriptor or set of mappings. Hopefully this can be avoided, as it would require merging the descriptors manually or risk losing one set of mappings over the other when adding the descriptors.
Best Regards,
Chris

Pallet putaway strategy question

Dear all,
I am new in the pallet putaway strategy and need your experience advise if you have done this.
Question.
1 - To use the pallet putaway strategy (i.e. P), do I need to configure the Storage Bin Type search (i.e. spro > logistics execution > wm > strategies > activate storage bin type search)?? Is it compulsory?
2 - To use the pallet putaway strategy, the storage type MUST BE a SUT-managed and that the "SUT check activate" checkbox MUST Checked, am I correct?
thanks
Tuff

Hi,
the storage bin type search and the storage unit type check more or less is the same. You have to define storage unit types, storage bin types, assign which SUT goes into which SBT. Well, and then you activate the check.
You need to do this for the pallet strategy. You do NOT need to activate the storage unit management in a storage type with the pallet strategy.
Best regards
Juergen

Kernel upgrade strategy question

First of all congrats to the community for a successful upgrade to 2.6.31. I had the usual mismatch in timing this morning with Virtualbox, and while tempting to remove VB, patience prevailed for a few hours and upgrades for VB as well as the kernel showed, and all worked smoothly.
My Question:
Why do we upgrade the primary kernel AND the fallback at the same time? For example ubuntu retains the old kernels in menu.lst in case of problems.
I suspect i know at least part of the answer, that it is related to the rolling release model, and that apps designed for the newer kernel might not work with the old one anyway. However would having a fallback on the prior kernel not at least offer a means to boot up and look at your system in event of panic?
Last edited by chender (2009-10-10 20:58:28)

That's not a fallback kernel. It's a fallback initrd. The only difference is that the fallback contains every driver that could be useful for booting, rather than just the ones detected as needed when they are built.
If you want an actual fallback kernel, install kernel26-lts.
Edit: too slow.

Another modeling and architecture question

Hello,
For some reason I still can't get my head around DocDB for more complicated relationships...
An extreme example in my app is a Practice Session. A session contains many attributes and could have multiple tasks, resources, songs, play-lists, and exercises. All of these items are modeled separately and can be added through their own forms.
Therefore lists of these items can be selected to add to a session but they also exist on their own.(to add to other types) I understand in a relational model how these multiple items can be added to a session. Relations through integer foreign keys
etc make sense there. In documents of JSON on the other hand I don't understand how to save these files and then correctly query them.
Lets say I have a practice session form that adds all these multiple items when submitted to a session
document.
here is a model of a practice session:
public class PracticeSessions : Document
[Key]
[ScaffoldColumn(false)]
[JsonProperty(PropertyName = "id")]
public string objId { get; private set; } // session_ID (Primary key)
[JsonProperty(PropertyName = "name")]
[Required]
[Display(Name = "Name")]
public string Name { get; set; } // session_name
[MaxLength(500)]
[Display(Name = "Content")]
[AllowHtml]
[JsonProperty(PropertyName = "content")]
public string Content { get; set; } // session_content
[JsonProperty(PropertyName = "practiceResources")]
[Display(Name = "Resources")]
public List<PracticeResources> PracticeResources { get; set; }
[JsonProperty(PropertyName = "songLearnList")]
[Display(Name = "Song Learnlist")]
public SongPlaylists SongLearnList { get; set; }
[JsonProperty(PropertyName = "learnSongs")]
[Display(Name = "Learn Songs")]
public List<Songs> LearnSongs { get; set; }
[JsonProperty(PropertyName = "songPlayList")]
[Display(Name = "Song Playlist")]
public SongPlaylists SongPlayList { get; set; }
[JsonProperty(PropertyName = "playSongs")]
[Display(Name = "Play Songs")]
public List<Songs> PlaySongs { get; set; }
[JsonProperty(PropertyName = "studyTasks")]
[Display(Name = "Tasks")]
public List<StudyTasks> StudyTasks { get; set; }
[JsonProperty(PropertyName = "practiceGoals")]
[Display(Name = "Goals")]
public List<PracticeGoals> PracticeGoals { get; set; }
[JsonProperty(PropertyName = "exercise")]
[Display(Name = "Exercises")]
public List<IPM2014.DataAccess.Exercise> Exercise { get; set; }
[JsonProperty(PropertyName = "objectType")]
public string objectType { get { return "practiceSessions"; } }
[JsonProperty(PropertyName = "userId")]
public string UserId { get; set; } // UserID
public PracticeSessions()
PracticeResources = new List<PracticeResources>();
Exercise = new List<Exercise>();
PracticeGoals = new List<PracticeGoals>();
StudyTasks = new List<StudyTasks>();
PlaySongs = new List<Songs>();
LearnSongs = new List<Songs>();
Practice resource:
public class PracticeResources : Document
[Key]
[ScaffoldColumn(false)]
[JsonProperty(PropertyName = "id")]
public string objId { get; private set; } // resource_ID (Primary key)
[JsonProperty(PropertyName = "name")]
[Display(Name = "Name")]
public string Name { get; set; } // resource_name
[JsonProperty(PropertyName = "description")]
[MaxLength(200)]
[Display(Name = "Description")]
[AllowHtml]
public string Description { get; set; } // resource_description
[JsonProperty(PropertyName = "notes")]
[MaxLength(500)]
[Display(Name = "Notes")]
[AllowHtml]
public string Notes { get; set; } // resource_description
[JsonProperty(PropertyName = "type")]
[Display(Name = "Type")]
public string Type { get; set; } // resource_type
[JsonProperty(PropertyName = "link")]
// [DataType(DataType.Url)]
[Display(Name = "Link")]
public string Link { get; set; } // resource_link
[JsonProperty(PropertyName = "image")]
[Display(Name = "Image")]
public byte[] Image { get; set; }
[JsonProperty(PropertyName = "objectType")]
public string objectType { get { return "practiceResources"; } }
[ScaffoldColumn(false)]
[JsonProperty(PropertyName = "userId")]
public string UserId { get; set; } // UserId
If items are selected from say a checklist box (of practice resources) I could capture the "ID" of each resource into an array and send that to the controller. At that point though the type is a string not an object of the list type I am
adding. There is then a mismatch of types. How do I add the resource items to the session document? It won't work to just add the ID strings. Do I need to query back to the practice resource documents to get full objects to enter as a list? Even
if I do this and it may work I end up with the whole practice resource object inside the session document and if anything changes in the original it will be forever out of sync. Does it even make sense to try to do this in a doc database? I
really like the lack of a schema and other features of Doc DB but I don't want to try to go forward with something that isn't the right choice. Should I go back to using SQL Server and EF for
this? Thats what I was using originally but was worried about schema changes and scale.
Sorry for this long winded question but I need to know if I should change my DB back end before going any further. Please let me know if you need more detail than this.
Thank You

hello and thanks for your reply, I probably will e-mail you so we can talk a little more about this. I think I am doing part of what you mention "A
common approach would be to store "type" and "id" as separate fields," I just call the type, objectType. I would like to use the composite Id's but I don't know what the best practice is to create them (not to mention other products,
but RavenDB takes care of that for you) This would also make the document names 100% more friendly when browsing them. What is the best way to manage these so they are unique? My biggest question though is still how to model and create these documents correctly.
I have added below example JSON that currently gets created.
[JsonProperty(PropertyName = "objectType")]
public string objectType { get { return "practiceResources"; } }
[JsonProperty(PropertyName = "objectType")]
public string objectType { get { return "practiceSessions"; } }

Airport Express -- old model vs new - question

On the Ariport Express Wiki page, it states that the old model A108x does not have "Wireless-to-Ethernet Bridge mode" while the newer (A1264) model has it. If in fact the newer model does have this, what does it allow one to do vs having the older model? ( I have the older model )
Thank you.

OK, let me see if I've got this right: if I had an older model Express as my base model and another older model used to extend the signal, I could not use the available ethernet port of the second express to connect to a laptop that does not have a wireless card and access the internet on that laptop.
No that is not correct. You can configure the two 802.11g AirPorts in a WDS. The second Express' Ethernet port WOULD be enabled for wired clients.
But if I had two of the newer models (or an extreme as my base and one newer express), then I would be able to use the express' port to wire into the laptop and access the internet. Yes?
Sorry, if I am causing you additional confusion. You basically have three choices to enable the second Express' Ethernet port for wired clients:
Using two 802.11g AirPorts, configure them for a WDS.
With one "g" and one "n" AirPort, configure the "n" AirPort as a ProxySTA.
With two "n" AirPorts, configure both for an extended network.

PO Release strategy question

Hi,
In PO release startegy,
Plant- XXXX
YYYY
BLANK
Purchase group, Total net order value, order type are the characteristics currently defined.
PO is created at company code level..with multiple plants-i mean, XXXX, YYYY.
rekease strategy does not work in case, if line items have account assignment and item category.
pl help

CEKKO is a structure for purchase order header.
The plant in purchase order header is only filled in case of UB stock transport order, where you do not have a vendor, here you would only have the supplying plant.
You are talking about plant in item level, which is requesting plant, not the supplying plant.
You can never reach your goal until you CHANGE your design.
you either create only POs which have only items of one single plant (must be controlled via user exit) or you just cannot have a release strategy that works. It is just black or white.

ME54N Release strategy question over delivery tolerance limits

I set up a release strategy base on the over delivery tolerance level. My problem is when a Purchase requisition is saved as rejected, and i click on the button cancel reject it deletes the last release strategy level because now it is looking at the actual total value disregarding the over delivery tolerance level.
It works fine when the Purchase requisition is not rejected, and i can cancel or reject the purchase requisition without saving it and it does not delete the last line of the release strategy taking into account the over delivery tolerance level. I am using the user exit ZXM06U13.
Can someone give me some insight into this ? Thanks.

Hi Siva:
You should request the development key for this structure under your SAP system, then you can add the extra fields in CEKKO.
Good luck

Client Strategy questions with BPS in mind

We are implementing BW and BPS.
The system landscape in my project has been planned to have different client numbers and different logical systems for each environment for BW and Source Systems (Dev, Quality and Production).
With BPS I am foreseeing issues when transporting the retraction structures, once they carry the client number (transaction UPB_STRUCT)
I could not find a conversion table for this case (like we have for BW - RSLOGSYSMAP).
And in this case (transaction UPB_STRUCT) the objects will carry the client number + planning area name (/1SEM/_YS_CHAS_400ZEXP0001).
1. So I conclude that the client number HAS to be the same in all BW environments (Dev, Quality and Production). Could you confirm this?
There are configurations for public sector retraction, where the logical system name is used to map the queries into the Funds Management BCS fields. (SPRO -> Define field assignments for plan data transfer from BW)
2. Given this configuration mentioned, is it REQUIRED to have the same logical system name in all BW environments?
Ive seen a presentation from SAP (SAP BW System Landscape Strategies / Mayer) with certain recommendations like the ones found in the OSS note 184447:
     You thus should have the following over all system landscape
BD(BW1CLNT100)->BC(BW1CLNT100)-> BP(BW1CLNT100)
   ||                  ||                  ||
   ||                  ||                  ||
OD(QS1CLNT300)->OC(QS1CLNT300)-> OP(QS1CLNT300)
That presentation also mentioned thats possible to have multiple Logical System names for BW in multiple environments.
Please give me your thoughts having in mind BW-BPS as part of the implementation:
3.     Should we have SAME Client number and SAME Logical system name in all environments for BW?
4.     I dont see any impact for source system perspective with logical names, do you?
5.     If you tell me that BW can handle different Logical System names, could you tell me where to configure to have BPS objects and retraction query mappings pointing to the right logical systems and client numbers the transport process (equivalent to what RSLOGSYSMAP does for source systems).
Thanks

Hello Alex,
I strongly recommend to have identical client numbers in your landscape (especially if you still have the choice). BW handles only one client anyway and there is no benefit of having different client numbers.
One client number will take care of BPS issues and you can hardcode structures and ABAP to the client number. Trust me it will make your life easier down the road.
BPS itself does not depend on the logical system name. If there are connecting applications, they have to take care of the mapping like BW does. But this depends on the application.

Org. Attribute Inheritance Model and Strategy

Hi all -
We are currently replicating the org. from SAP HR, but are looking for any suggestions on defining an attribute inheritance model for SRM specific attributes.
Any suggestions? The org has approximately 15,000 positions.

Hi,
The following attribute which is common to all the users can be inherited at the Organisation level.
Say for Example there are 5 organisation
for Org : 1 :Common attribute : These are the attribute common for say 200 employees so you can give at the org and tick
the inherited so that you can again enter the same for all the employees.
ACS
BWA
CAT
CNT
EXT_ITS
KNT
ROLE
SYS
VENDOR_ACS.
Like this first chart out and give the attributes

Another Release Strategy Question - Multi currency

Hello,
I have been searching for an answer to my delema to no avail on this board, but no answer yet.
My problem:
We have a Purchase Req. strategy with approval by Plant, Cost Center, and Total PR Value.
The PR Value Characteristic is in US Dollars, but one of our companies is in Europe so we also need to have a PR Value Characteristic in Euros.
Currently we have:
Characteristic: Z_PR_AMT referencing field CEBAN-GFWRT. This is in US Dollars.
                         Z_PR_WERKS referencing field CEBAN-WERKS
                         Z_PR_KOSTL referencing field CEBAN-KOSTL.
Class:              Z_PR_CLA with references to Characteristics: Z_PR_AMT, Z_PR_WERKS, and
                         Z_PR_KOSTL.
Release Group: A1 that is assigned to class Z_PR_CLA
Also, currently all PR's under $1000 (US Dollars) go through Workflow for release, and if the PR is over $1000 (US Dollars), requires a 2nd release.
But, since we have a company in Europe, we also need to be able to have a Release Characteristic for Euros so that PR's in Europe under 1000 Euros go to a new release strategy, and PR's in Europe over 1000 Euros go to a 2nd release strategy.
Can I add a new Characteristic to the Z_PR_CLA refering to the same CEBAN-GFWRT field, but use currency EUR (lets say Characteristic ZPR_AMT_E). Then in CL20N (Classifications) when I am adding the actual values, leave the value information blank for the European Amount characteristic and fill in the US Amount and assign to a US Release Strategy.   Then leave blank the US Amount charastieric field and fill in the European Amount characteristic field for Europe Release Strategies?
Will this work?
Thanks in advance.

That is the problem we are trying to avoid. We do not want to have to put in a manually converted 1,000 Euros to US Dollars.
Currently we have a US Dollar limit for our European plant set at $1,474.30 which is to represent 1,000 Euros. But this number changes with the fluxuation of the currency rates.
So far in testing I do have 2 Characteristics defined for Currency, one for US Dollars and the other for Euros. Both Characteristics have amounts loaded in them (via the CL20N screen).
I do see in my debug sessions that there is a currency conversion to foreign currency in the LEBNDF01 include program, but since I have 2 Characteristics for Currency in the CL20N screen for this particular Release Strategy, this is messing up the conversion to foreign currency.
I still have more debugging to go.

General Persistence Implementation Strategy Question

Hi,
I want to implement a J2EE application and use a persistence system like Hibernate. I will have to create several beans and set-up my ORM properly. Now, if I create an Enterprise project in NetBeans, where should I put my Peristence code? In a Web container or in a EBJ container knowing that both JSP pages and EJB will refer to my persisted beans? Or should I create another separate project and include the corresponding .jar in both my Web or EJB containers?
What is the best strategy?
Thanks,
J.

knowing that both JSP pages and EJB will refer to my persisted beans+? I would say that JSPs should not be contacting your database directly. Better to go through a well-defined service layer that hides the persistence layer. All security, binding, and validation issues should be resolved before the service layer is called.
Or should I create another separate project and include the corresponding .jar in both my Web or EJB containers?Both? Wrong.

Distribution Model Filter - BD59 question

Hi,
if you have a look at BD59 (assign Objecttyp) for example "CREMAS", why is ALE-Objecttyp "MSGFN" used ?
MSGFN is filled in several Messagetypes "but" not showing in distribution model filter.
What is the use of MSGFN as Ale Objecttyp ?

Hello,
The Field MSGFN is a Qualifier / Action Code / Action Field which need not be mandatory. So, probably thats the reason why is not showing up.
Thanks and Regards,

Oracle's locking strategy question

I have a question related to Oracle's locking mechanism which I understand is related to taking "snapshots in time" to avoid writers blocking readers (which happens in SQL Server).
Suppose I had a table T1 with 1 billion records and column C1 = 4 in every row. Suppose the following events occur:
12:00 update T1 set C1 = 5
12:01 select C1 from T1 where ... (and this statement returns only one row)
1:00 the update statement executed at 12:00 finally finishes
Would oracle return the value 4 regardless or which row was selected at 12:01?
Why would this be more correct than locking the table and waiting until 1:00 and returning 5? Sure, this would be a long wait, but at 12:00 a command was issued to set every value to 5!

You are question is related to oracle transaction
control and read consistency in the database in
Oracle database all the SQL and DML runs with SCN
timestamp.
for example
Session 1 SQL 12:00 > UPDATE t1 SET c4=5 ;
---assuming this runs for an hour
before updating c4=5 it takes the snapshot of the C4
column data and keeps in
UNDO segments to make other sessions read
consistent.
Session 2 SQL 12:01 > SELECT c4 FROM t1 WHERE ....
this will return 4 as the DML is not yet comminted in
the Session 1
To happen this Oracle database server process reads
the data from UNDO to answer your question.locks are
matianed at the database BLOCK header level.
Let me put a simple thought here
You have two debit cards issued for one account one
is with you and the other one is with your beloved
one.Balance in your account = Rs 40000
1) at 12:00 you went to a ATM and inserted your debit
card to draw amt Rs 20000
and your transaction is still processing ( you not
recieved the cash)
2) at 12:01 your beloved one went an another ATM and
interested to see the balance so do you think Rs
40000 should be shown or Rs 20000.
hope you got some ideaNot to pick nits, but I think this is a bad example. If you had such an important action (especially if it was going to take a long time to complete) you would/should have some kind of lock on modifying the account value so that this very thing couldn't happen! Only one transaction at a time gets to update the balance. In a sense, that might make Oracle look like the SQL Server you appear to be familiar with (the 2nd transaction would wait. A very long time!) But for a bank account type transaction, you almost have to.

Release Strategy Question

Hi,
Can anyone explain me with example, why is it that we can have only one class and not more, when configuring groups in the release strategy.
Why is it mandatory to have only one class for overall and one class for line item release, can someone explain with examples.
The system allows creation of multiple groups, but all have to use the same Class when it comes to overall release/ Line item release.
I am not able to understand the reason behind this restriction as of now, can someone share some insights.
Thanks
Shailesh

Hi,
Better & always keep one release class ....ie.......one release class for PR, one release class for PO, one release class for Contract & one release class for SES.Under each separate class keep your requires characteristics.Then do necessary confuguration for release statergy.
